A Va-Tran Systems Sno Gun-II Cleaner was used in combination with compressed liquid carbon dioxide. The compressed cylinder was equipped with a syphon tube to facilitate the making carbon dioxide snow.
Additionally, a BCS Co Soda Blaster was used with Church & Dwight Baking Soda Maintenance Formula XL with SuperKleen rinse accelerator. The baking soda blasting was rinsed from the part using tap water and dried using air blow off.
The supplied aluminum plate was first photographed to record its initial appearance. The part was then cleaned with the CO2 snow for 2 minutes. The flow of the snow passed across the plate in a side to side and top to bottom pattern during the 2 minutes of cleaning. Only a half of the part was cleaned so that a direct comparison could be made with the original condition. The finish of the part also was compared to the desired finish on the back side of the part. A photograph was taken of the cleaning.
The process was repeated for 5 and 10 minutes of cleaning.
Baking Soda blasting was performed on the other half of the supplied part for 2 and 5 minutes.
