Review on SALVMARY Grill Cleaning Brick Block Stone - 5 Pack, Gray + White: Remove BBQ Grill Grease, Griddle Stains, and Toilet Residues Effectively by Holly Walker

It exceeded all my expectations. It cleaned a stubborn stain around the toilet that no other cleaner or item could remove. This little tool required some pressure to use, but the overall pressure required was moderate and it took about 5 minutes at most to completely clean up the mega stain. It's not hard and won't damage the surface of the toilet (I was afraid it would scratch or damage the porcelain, but that didn't happen). It breaks down into very small pieces that quickly and easily dissolve in water. Other than that, this thing was AMAZING. Can't wait to try it on other devices.
