Clean engine parts, marine hardware, and mechanical components without solvents, hazardous chemicals, or special disposal requirements. CRC Smartwasher® BT5 is a bioremediating degreasing solution — the first of its kind to deliver professional parts-washing performance at room temperature using a biological cleaning process rather than harsh chemistry.
BT5 works by using naturally occurring microorganisms that actively break down petroleum-based grease, oil, and grime into harmless byproducts. The result is a degreaser that cleans effectively, stays active over time as the biology replenishes itself, and doesn’t require the hazmat handling, ventilation, or disposal protocols that solvent-based cleaners demand.
- Bioremediating formula — microorganisms actively break down grease and oil at room temperature
- Ready-to-use at full strength — no dilution required
- pH neutral, non-hazardous, non-flammable, and non-irritating
- No special disposal requirements — safe for standard drain disposal where permitted
- Designed for use with CRC Smartwasher® parts washing systems
- Tackles heavy petroleum soils, grease, oil, and carbon deposits
Parts Desk Insights
Best Use Case: BT5 is the solution of choice for shops and boatyards running a CRC Smartwasher® parts washing unit who want to eliminate solvent-based cleaners from their workflow entirely. It’s particularly well-suited for cleaning carburetors, fuel system components, throttle bodies, valve covers, and other engine parts where solvent residue or flammability is a concern. Because it’s non-irritating and non-hazardous, it’s also a safer option in enclosed engine rooms or spaces with limited ventilation. Replace the solution when cleaning performance noticeably drops — the biology has a finite lifespan depending on soil load and usage frequency. Store at room temperature and keep the container sealed when not in use to maintain biological activity.
