Review (5/5): Works way better than CLR
I purchased this product hoping that it would help with stains/deposits on my new light colored quartz countertops around the kitchen faucet. I was pleasantly surprised. I sprayed the product on the stains, let it sit for about two minutes, then used a softer scrub sponge. The stains came off easily. I also used it on porcelain sinks in a bathroom, worked great there too.
