CLR PRO Heavy Duty Mold and Mildew Stain Remover, 1 Gallon Bottle | Bleach-Free, Unscented Multi-Surface Stain Remover, Works on Tile, Wood, Concrete, Glass and More

I have outdoor curtains – about 20 of them creating a private space in our yard. We had a lot of rain this spring and we started to get mold spots and even some green mossy streaks. I wanted a cleaner without bleach and this worked very well! I got a sprayer and coated the multiple curtains at once. I used a deck brush to scrub what I thought would be stubborn spots and that seemed to help – but once the curtains dried the overall appearance improved greatly, even where I did not brush! It did a great job without creating a toxic cloud. Also, I used it to clear some stains in colored grout in our shower. It substantially reduced stubborn spots, I will take another pass to see if I can fully remove those marks!

Nice

Works great, I used it in my granddaughter's car from the smell of mold in her car from leaving the windows partially open

Cleaned the glass door in my shower very well. It had quite a few months of build up on it.

Sort of Works but takes several applications and water rinsing when trying to remove mold on stone and concrete. It does not work on rust stain on concrete.

A complete waste of money and time.. This product has zero effect on mold or mildew.

The word 'pro' in this case means nothing. It works no better than the regular/ cheaper version

I bought this to use on my boat’s upholstery. Was going to use a bleach solution but determined that the caustic effect that bleach has on upholstery. This product is not only gentle on fabric, it is every bit as effective as bleach in removing mold and mildew. (Unsure whether it disinfects as bleach would.) I now also use this around the house when mildew tends to show up. Just spray it on, let it sit for 25-30 seconds, and just wipe off. EZPZ. Will make sure I ALWAYS have a supply of this.
