Review on Chemical Guys SPI22016 Protectant Fluid_Ounces by Daron Ellis

Cleans some stains and areas that have not been rubbed with dirt for a long time. I tried cleaning the tonneau cover but nothing happened. The soft top is 10 years old and has never been cleaned, mostly just folded in the boot of a convertible. I couldn't see the old dirt coming off no matter how hard I rubbed and didn't let it in. Finally used detergent and hot water and I saw the gray dirt come off. Use this product on new surfaces and you should be fine.
