This product does exactly what it is supposed to do with very little effort. Would like to see it come with a sprayer for the smaller bottle designed for the product it dispenses. I put a all purpose atomizer on it but it eats away at the pump and stops pumping but sure saved a lot of time and less stooping. I also used a long handled wash brush to lightly scrub the badly stained areas prior to rinsing.When you applied the product you could see the scum near disappear before your eyes.
