SSC Cleaner

Preferred has licensed a unique cleaning method from NASA. The cleaning technology is applicable to both large and small cleaning tasks. The unique method results in effective cleaning with a minimum of spent liquid.

Benefits

• Cleaning with a minimum of runoff liquid
• Easily portable and adaptable
• Adapts to the use of other clear non-flammable liquids
• Can be used to verify cleanliness by run-off analysis
