Blasting Facts
Dry Ice Blasts Graffiti

Graffiti left unremoved invites more serious vandalism. Whether it's a marking pen on a painted surface or big wall art on bricks or blocks, quick removal helps maintain property value and preserve good company image. Dry ice blasting for graffiti removal offers many advantages:

• one pass cleaning saves time and labor
• no harmful solvents
• no cleanup afterward -- the dry ice just evaporates
• no water blasting mess
• no soda blasting film residue to remove
• no hazmat residue disposal costs
• no odor or dust to contain
• gentle, non-abrasive cleaning of wood or delicate architectural features
• equipment can be rented, saving capital costs
• no expensive hazmat training or protection for operators

 

OTHER USES

HOME MADE ROOT BEER
To make one gallon of root beer: One pound sugar One gallon water Two ounces root beer extract Add 1 to 2 pounds of Food Grade Dry Ice to carbonate. Tip for carbonation: put in a triple size plastic container (1/3 liquid and 2/3 air) and put the lid on tight. The pressure will dissolve more into the mix and make it fizzier. Otherwise have Club soda to add for carbonation. If you let the root beer fog too much you will loose the carbonation. Bring several pounds extra dry ice and put in as you are serving in order to let the kids see the fog affect. You must keep the root beer from freezing. Dry ice is -109.3°F and it will freeze the liquid. Add extra water if freezing starts. Do not ladle Dry Ice into cups. Put regular ice directly into cups for additional cooling. For different ideas add dry ice to grape juice and pineapple juice for a goolish witches brew.

CARBONATE LIQUIDS
When CO2 is added to plain water it will make sparkling mineral water. CO2 is extensively used throughout the world in the beverage industry for making soda pop.

DENTS & HAIL DAMAGE
Dry Ice will condense metal and thereby shrink small dents on your car. Place the Dry Ice on the inside of the dent if possible. Use heavy gloves and press flat sheet against dent. If it is not possible to get on the inside concave part of the dent, then using heavy gloves hold the Dry Ice so a corner can fit into the bottom lowest part of the cratered dent. Hold the Dry Ice until the metal is frosted at least 2 inches beyond the dent. Let the metal warm up (in the sun is the best) and repeat the procedure. Sometimes the dent will pop out perfectly. More often it will not be possible to get a flat smooth finish, but the dent will be reduced noticeably. Creased metal will still show the crease line but the dent will be far less pronounced. I have not seen any paint damage, but I'm sure if the paint is not strongly adhered, it could peel away.

FOOD STORAGE
Placing Dry Ice in the bottom of a dry food storage container is a very economical way to fumigate and store dry goods for an extended amount of time. Make sure the Dry Ice is not frost covered, as that will add moisture. Put one to two ounces of Dry Ice per five-gallon storage container in the bottom and then pour in the dry food. As the Dry Ice sublimates it replaces the oxygen in the container with CO2. Leave the lid on but not tightly sealed until the Dry Ice completely sublimates. Then snap the lid tight. Without oxygen neither bugs nor bacteria can grow. This process is good for seeds, grains, legumes, flower, powdered milk, etc. An excellent site for further information can be found at Walton Feed Inc: http://www.waltonfeed.com/self/upack/dryice.html

REMOVE FLOOR TILE
Dry Ice will loosen floor tile by freezing and slightly shrinking them allowing easier removal. The cold temperature of the Dry Ice will break the bond of the adhesive. Place the Dry Ice sheets centered on the tile to be removed and wait until it is completely frosted. If it has not popped off, slight tapping with a hammer or prying with a screwdriver will allow it to be lifted off easily. It is too time consuming to remove a whole floor, but is ideal for removing a few tiles that need replacing.

GOPHER ERADICATION
Dry Ice is heavier than air so it will find its way to the bottom of gopher dwellings. Place 1 to 2 inch pieces as deep into each hole as can be reached and fill the front of the hole with dirt. If you miss some holes the process may have to be repeated. Jerry Yamamoto of Hayward, California reports that he successfully used Dry Ice to eradicate regular Argentine ants from his front yard. Perhaps this could work on fire ants too.

PROTECT SPORT FISH AND GAME
Pack your trophy animal or fish in Dry Ice to minimize spoilage while transporting or shipping it home. Do not let the Dry Ice touch the game directly as it may cause superficial damage. Dry Ice can be added to regular ice to extend its cooling. For best results use an insulated container.

BRANDING
Dry Ice is used to super cool alcohol for branding horses, cattle, and hunting dogs. The alcohol must be 90% pure - not rubbing alcohol. Methyl alcohol is most commonly used. Liquid Nitrogen is too cold to work properly. This is now the second most common way to brand according to Tony Clark of Bassett, Nebraska.

MEDICAL
Doctors, to freeze skin for wart removal, use Dry Ice or liquid nitrogen. Many medical offices ship biological specimens in Dry Ice for laboratory testing or further processing. Dry Ice is also used to keep bone morrow frozen when it is shipped.

TRANSPORTING PLANTS
Dry Ice will keep flowers cool and delay blooming. Maintaining ready to flower plants at 34°F will retard blooming. Do not allow Dry Ice to get too close and freeze plants.

PLANT GROWTH
A small additional amount of Carbon Dioxide will increase the rate of plant growth.

CHEMICAL RETARDANT
Its low temperature slows or stops some chemical reactions. It is used to store and ship special adhesives It is also a neutralizing agent for alkalis.

PRESSURIZING AGENT
When Dry Ice changes from a solid to a gas it absorbs heat and expands to over 800 times its original volume.

INERTING MEDIUM
Dry Ice will replace oxygen in a container preventing or putting out fires. It is used to safely remove underground gas storage tanks.

SHRINK FITTINGS
Dry Ice will shrink metal to slide on sleeves, bushings or bearings. Add Dry Ice to a 90% pure alcohol bath to create a cold liquid near -109.3°F. that can be used like liquid nitrogen.

DEFLASHING MOLDED PLASTICS AND RUBBER
Dry Ice will cool and shrink whatever it touches. Rubber parts are tumbled in a barrel with Dry Ice, making them brittle for easy flash removal. It is used in cold grinding of Plexiglas, PVC resins and vinyl's.

FRESH MEAT PROCESSING
Dry Ice will keep the temperature cold and reduce spoilage while processing meat. This is used in industrial processing of ground meats and sausages.

MOSQUITOES
CO2 may attract mosquitoes away from animals and people. Place pieces of Dry Ice away from areas where people are congregating. The theory is that mosquitoes find animals and people by their CO2 exhaled during breathing. Melissa Palm reports that dry ice does attract mosquitoes. "I use dry ice in some of my mosquito traps as bait and find that it works rather well." The Clarke Family of Companies of Roselle IL., sells a mosquito trap designed for using Dry Ice.

WELLS
Dry Ice combined with detergent, or alone, will improve porosity in irrigation wells. Bill Hayoz of Reliant Dry Ice in New Mexico, explains that dry ice is used regularly by the ranchers to improve water flow. He used about 60 pounds of dry ice in his windmill well, capped it off, and waited several days before the water came back with a greater flow.  The city of Mosquero used 800 pounds of dry ice for their city wells. Most well men will use dry ice before drilling deeper.

OIL INDUSTRY
Dex Welch reports "Dry Ice has been used in the oil fields for years to clean tank bottoms. When paraffin, sludge, etc build up, a chemical is added along with Dry Ice to roll (stir up) the tank bottom. This breaks out the liquids & separates water from oil in paraffin mixtures so that water can be removed & the oil saved." Liquid CO2 is also used to crack and increase oil flow in wells.

BAKING INDUSTRY
Dry Ice is used in mixing ingredients and retarding yeast growth until the proper time.

FREEZE FRESH STRAWBERRIES PERFECTLY
Karyn Gilbert writes: "I use Dry Ice to freeze my strawberries - fresh, washed ones, once a year:  

Wash fresh strawberries
Place directly on top of dry ice in cooler for about 20-30 minutes
Close cooler
Remove when solid
Place in freezer safe plastic bag, mark with date
Place in freezer - to thaw take out and set on plate at room temp (use within a year to be sure freshness)
They will thaw almost like fresh - without being soggy like usual frozen strawberries are.

I suppose this might work for other fruits and veggies because of the quick freeze time, not allowing them to get soggy..."

FUMIGATION - Powder-Post Beetles in Furniture
Jim Lockhart of Littleton Colorado writes: "After allowing the infected cabinet to spend 18 hours in the closed freezer with 30 lbs of dry ice at -25 deg F, I went ahead and removed the dry ice, saving what was left of it in a small ice chest. I closed the freezer up again and allowed the cabinet inside to slowly warm up to room temperature (another 12 hours) then took it out. I checked for signs of life with a stethoscope in the places where the powder post beetles could be heard and – not a sound. I checked again for signs of life 24 hours later – still nothing. It would appear that the insects either froze, suffocated or both. Of course I have no way to tell whether or not the freezing or lack of oxygen also killed any eggs – only time will tell. I am confident enough at this point that this worked and would recommend it to anyone in a similar situation. Feel free to include any and/or all the info I’ve given you on your website. This is a much less toxic way of killing insects than the use of chemical sprays and fumigants."

Jim writes one year later to update there is no sign of any beetle activity and "I’ve been telling fellow woodworkers about the idea and they, too have met with success without doing any damage to the wood or it’s finish."

 

 

POWER OUTAGE
BROKEN REFRIGERATOR,  BROKEN FREEZER

Dry Ice will keep things frozen when the power goes out or the freezer breaks down.
 

POWER OUTAGE
If the electricity is out for a brief period of time keep the refrigerator and freezer closed and everything will be all right. The time everything will stay frozen or cool will depend on the type of freezer or refrigerator, the thermostat setting, and the temperature surrounding the appliance. Generally speaking on a hot summer day after the first hour, for every hour off, an equivalent day of storage will be lost for refrigerated items. Three to six hours could represent two to five days of storage. For the freezer, depending on how full it is, (the more full the better) things will stay frozen from three to six hours in a refrigerator freezer and up to twelve hours for a chest freezer.

ONLY TAKE ACTION IF THE POWER IS EXPECTED TO BE OFF FOR A LONGER PERIOD OF TIME!

Follow the directions for each appliance below:

FREEZER NOT WORKING
Do not touch Dry Ice directly. Use insulated gloves, potholder, towel, etc. Use the following guidelines for each type of freezer. For each 24-hour period:

(1) Freezer on bottom: use 15 to 25 pounds.
(2) Freezer on top: use 20 to 30 pounds.
(3) Side by side Freezer: use 30 to 40 pounds. Place each slab, starting with the top shelf, on top of the food to be kept frozen. Bottom shelves will be kept frozen by the Dry Ice above it.
(4) Chest Freezer: use 40 to 50 pounds. When taking out the frozen food, carefully lift the dry ice slab up with gloves, potholder, towel, etc., without touching the dry ice directly.

REFRIGERATOR NOT WORKING
For each 12 to 24 hour period, place a ten pound slab of Dry Ice on bottom shelf of the refrigerator to cool. Do not touch Dry Ice with bare hands. Do not place it directly on the glass shelf, but use newspaper or other insulated protection between the Dry Ice and the shelf. When the Dry Ice is sublimated replace it with a new slab. Keep extra Dry Ice in an ice chest. Because Dry Ice is frozen CO2, it will carbonate open containers. Carbonated water is OK but carbonated milk sure tastes different! Also anything too close to the Dry Ice may freeze. Watch out for items below the bottom shelf as they may freeze too. Regular block ice is better for the refrigerator - the old fashion "ice box" - but then the melted ice water must be removed.

DISPOSAL
When finished with the Dry Ice, unwrap and leave it at room temperature in a well-ventilated area. It will sublimate from a solid to a gas. DO NOT leave Dry Ice unattended around children. If you would like a fantastic simulated volcano, run hot water and put the remainder Dry Ice in your garbage disposal. Use safety goggles and stand back. This will make a marvelous eruption.

WALK-IN FREEZER
A 12x12 walk in freezer will use 150 to 250 pounds per day. If the fans are running, place half the Dry Ice as high and close to the back of the evaporator unit where the air is sucked through. Place remainder slabs on top shelves directly on frozen food. Leave door open when entering the freezer. Carbon dioxide gas will accumulate in lowest areas and could cause suffocation. Use the buddy system with one person outside the walk-in at all times to help remove items from the walk-in. Leave walk-in if you start to pant and breath quickly or your fingernails or lips start to turn blue. This is the sign that you have breathed in too much CO2 and not enough oxygen.

WALK-IN REFRIGERATOR
A 12x12 walk in refrigerator will use 50 to 100 pounds per day. If the fans are running, place all the Dry Ice as high and close to the back of the evaporator unit where the air is sucked through. Otherwise, place slabs on top shelves without touching any food. Too much Dry Ice will lower the temperature too much and freeze food near the floor. Monitor the temperature closely after several hours. Add or subtract Dry Ice as needed. Keep extra Dry Ice in an ice chest. Leave door open when entering walk-in. Carbon dioxide gas will accumulate in lowest areas and could cause suffocation. Use the buddy system with one person outside the walk-in at all times to help remove items from the walk-in. Leave walk-in if you start to pant and breath quickly or your fingernails or lips start to turn blue. This is the sign that you have breathed in too much CO2 and not enough oxygen.

 

 

"SPECIAL EFFECTS"

DRY ICE FOG
Dry Ice when combined with hot tap water can produce vigorous bubbling water and voluminous flowing fog. For example, with 5 pounds of Dry Ice in 4 to 5 gallons of hot water, the greatest amount of fog will be produced the first 5 to 10 minutes. There will be far less fog for the next 5 to 10 minutes as the water cools down and the volume of Dry Ice diminishes. As the water cools, the fog becomes wispier. Dry Ice makes fog because of its cold temperature, -109.3°F or -78.5°C, immersed in hot water, creates a cloud of true water vapor fog. When the water gets colder than 50°F, the Dry Ice stops making fog, but continues to sublimate and bubble. The fog will last longer on a damp day than on a dry day.

HOW TO MAKE FOG
For each 15-minute period put 5 to 10 pounds of Dry Ice into 4 to 8 gallons of hot water. This will make lots of fog depending upon the temperature of the water and the size of the pieces of Dry Ice. Hotter water will make more fog. Very hot water will add its own rising steam to the vapor cloud. If there is no steam the fog will flow down hill and in the direction of any air movement. A small fan can help control the direction. Smaller pieces of Dry Ice with more surface area produce a greater volume of fog and cool the water down much faster. In both cases the result is more fog for a shorter amount of time. Keep the water hot with a hot plate, electric skillet, or some other heat source to produce fog for a longer time. Otherwise when the water gets too cold it must be replaced to continue the fog effects. If the container is completely filled with water the fog will flow over the sides the best. But the Dry Ice sublimation will vigorously bubble the water and splash it out. Even a ¾ filled container will splash some so place the container where spilled water will not ruin anything. The water vapor fog will also dampen the area it flows across. Be careful because after some time floors do get slippery.
