Rainbow® Presoak Powdered Detergent

I am convinced that, around 1997, car wash owners started spreading the word about these Rainbow products because sales started growing steady through now. This Presoak Powdered Detergent is a premium high foaming detergent.  Sure, it produces yellow, lemon-scented foam, but it's also a solvent-based formula that will not separate or fall out at high concentrations. We designed this detergent and the complete line of Rainbow products with one goal in mind: To cut your risk and help you grow your profits. Your Satisfaction Is 100% Guaranteed. Order Now.
