“We think the ROwasher is better than a solvent parts washer. The ROwash cleaning fluid cuts through oils just as fast, but because it is heated it breaks down grease much more quickly. Plus, the parts heated by the fluid quickly dry themselves. No blowing solvents into the air with airlines post cleaning.”

“The ROwasher could be the most profitable tool in your workshop. It makes our job much easier because we can clean a whole bike twice as fast as our previous spray and rag method. We wouldn’t be without it!”
