Maxima Racing Oils Bio Wash 32oz

It does everything it says it will. I spray and hand loosen the dirt under my YZ250 after riding. Then, I spray on the Biowash. It removes that film of dirt that remains. It actually dissolves (breaks up) thick mud too but it take more of the product to do that. I keep buying this product because it make my bike cleaning muck easier and more thorough. I only wish they offered it in a gallon jug so I didn't have to pay for and toss in the garbage, the spray bottle, every time the bottle runs out!

This stuff works absolute wonders. If you are trying to get some thick grime off use this and some agitation. Cleans air filters good also, doesn't eat up all the oil in the filter like gas does. I would 100% recommend this to anybody in the offroad industry.
