Chemical - Stain Remover - abc
I've owned and operated my window cleaning business for 30 years. Tried every hard water deposit removal product on the market over the years. While no single product is the one solution to every staining problem abc Stain Remover is right at the top of the creme based options. Priced right, it delivers great performance, stays well mixed in the bottle unlike some others, and does a great job when used in conjunction with a white pad and some elbow grease. If you're looking for a non-acid option for removing stains, add this chem to your kit and you will be glad you did.
