Schmidt Brewery Historical Building Restoration

When it comes to historical building restoration, Midwest Dry Ice Blasting has the right equipment and plenty of experience to bring  back the original beauty without causing harm to the structure or surrounding area. Gentle cleaning methods are required when restoring historical buildings such as the Schmidt Brewery in St.Paul. Traditional methods of cleaning would have involved plenty of scrubbing with a wire brush and possibly the use of chemicals. Dry ice blasting is environmentally safe and is definitely the preferred method for cleaning brickwork.  Notice the thick buildup of paint in this side-by-side comparison photo on the brick wall. The Midwest Dry Ice system restores old brick back to it’s original condition. This is just one more example of how we put our historical building restoration knowledge to work for our customers.  The Schmidt Artist Lofts are now open for business. If you are looking for an efficient way to clean bricks and get the job done right, consider harnessing the power of dry ice blasting and contact us...

Removing Mold From Concrete

Mold spores are constantly being deposited on these areas where you have plenty of  nooks and cranny’s. Add moisture and mold begins to grow. One option is to use harsh chemicals but that’s unsafe for the people involved in the cleaning and the environment. Midwest Dry Ice Blasting has been professionally removing mold from concrete and brick structures successfully without the use of harmful chemicals.

Fire Restoration clean-up with Dry Ice Blasting

Fire damage brings production to a halt at Kemps Dairy in Rochester MN in late January. Midwest Dry Ice Blasting to the rescue! We knew this would be a time sensitive project when we got the call and it put our crew and our Cold Jet equipment to the test. Once our crew was on-site we began restoring fire damaged walls, ceilings, floors.  Equipment had to be sanitized quickly to enable Kemps to get production up again. The long hours paid off and ice cream production is now back up at Kemps Dairy. Fire restoration is just one of our...

What is Dry Ice

What is Dry Ice

Dry Ice is Extremely Cold! Dry ice basically is the expansion of liquid carbon dioxide in a mold that creates solid snow like pellets at a temperature of -109.3F  It’s the same gas that we exhale and plants use use for photosynthesis. It is useful for preserving frozen foods, ice cream, etc. It is also extremely effective and safe to use for all types of commercial and industrial cleaning. Many people ask us how to remove graffiti, clean concrete, restore the original brick in historic buildings? With the right equipment and know how, dry ice is the preferred choice. You may also like to visit this page for more information. http://mwdryice.com/whatisdryiceblasting/ When dry ice is placed in water. sublimation is accelerated, and low-sinking, dense clouds of smoke-like fog are created. This is used in fog machines, at theaters, haunted house attractions, and nightclubs for dramatic effects. Unlike most artificial fog machines, in which fog rises like smoke, fog from dry ice hovers above the ground. Dry ice is useful in theater productions that require dense fog effects. Dry ice is the solid form of carbon dioxide (chemical formula CO2), comprising two oxygen atoms bonded to a single carbon atom. It is colorless, with a sour zesty odor, non-flammable, and slightly acidic. At pressures below 5.13 atm and temperatures below −56.4 °C (−69.5 °F) (the triple point), CO2 changes from a solid to a gas with no intervening liquid form, through a process called sublimation.  The opposite process is called deposition, where CO2 changes from the gas to solid phase (dry ice). At atmospheric pressure, sublimation/deposition occurs at −78.5 °C (−109.3 °F). The density of dry ice varies, but usually ranges between about 1.4 and 1.6 g/cm3 (87 and 100 lb/cu ft). The low temperature and direct sublimation to a gas makes dry ice an effective coolant, since it is colder than water dry ice forms and leaves no residue as it changes state. Dry ice is non-polar, with a dipole moment of zero, so attractive intermolecular van der Waals forces operate. The composition results in low thermal and electrical conductivity....

Toro General Golf Tractor One-of-a-kind

Toro General Golf Tractor One-of-a-kind

Toro General Golf Tractor Restoration –  Dry ice and crushed glass successfully used to restore 70 year-old historic tractor The Situation In early 1941, three Toro General Golf Tractor s were on the production line to be built for their respective customers. When World War II started, Toro stopped all domestic mower manufacturing in order to build tanks, cannons and anti-aircraft gun parts so the three tractors were put on hold. When the war ended, two of the tractors were finished and delivered to their original customers. One of the tractors was no longer needed so Toro removed the engine and rear end and stored it in the warehouse. This was before red became the staple color of the Toro brand so the tractors were painted “machine blue” – a trial color that they had on-hand. Minnesota Valley Country Club, located in Bloomington, MN, received one of the tractors and the other one was delivered to another Toro customer. In 1955, Minnesota Valley Country Club asked Toro if they would manufacture a pull-behind trailer for their tractor. This was not a common practice for Toro at the time but they decided to take the last production tractor that was in the warehouse and modify it for this need. They used the original frame and dump box from the tractor, installed a model ‘A’ front end for the rear end and installed a set of Toro wheels.  The Toro General Golf Tractor was built. This created a one-of-a-kind matching dump trailer for the country club. Midwest Dry Ice has perfected the dry ice/crushed glass paint and rust removal that eliminates panel warping and the need to use a grinder for safely removing old paint.
