Chemical Guys MicrofiberWash+ Cleaning Detergent Concentrate is for microfiber towels and accessories. Regular washing with powder detergents or retail washing detergent is harmful to the microfiber. Many strong retail detergents will destroy the absorbency of towels. MicrofiberWash+ is engineered for microfiber. Simply add 4-5 capfuls of MicrofiberWash+ to your wash to clean, restore and maintain microfiber time after time. MicrofiberWash+ not only leaves your towels clean but removes lingering bacteria and oils that may otherwise not be removed. Wax, polish, compound and most chemical build-up compromise the cleaning ability of microfiber as well as dramatically reduce the cleaning, buffing or polishing efficiency of the microfiber. Using inferior towel washes or household detergents leads to rapid discoloration, deterioration and stiffness greatly reducing the microfiber natural absorption ability as well as its longevity.
