Pumice Cleaning Stone with Handle Toilet Bowl Cleaner Hard Water Ring Remover for Bath/Pool/Kitchen/Household Cleaning 4 Pack

Much like knife sharpening stones, do yourself a favor and heed the instructions. The key to this, knife sharpening stones, or sandpaper is to let the hard abrasive material do the work. Using great pressure will not get it done any faster, but will wear down the stone faster, and possibly break it. More passes, and avoiding extreme pressure is best. The mind tries to tell you that more pressure is needed. but actually it is not any better at cutting the stain with great pressure. People often wear out sandpaper quickly by applying too much force, as they also do with often expensive sharpening stones. This is the same. Pick a spot and use light to medium pressure until the stain starts coming off. Heavy pressure just wears out the stone as well as your arm. Almost all abrasives are like that. Great pressure also packs the removed material in between the grit in the stone making it less abrasive.

not as strong as store bought ones

I needed a pumice for hard water deposits that have stained our toilets. These are are a great value and have made an improvement in the stains but it will take several attempts to remove. I wish the pumice was firmer and did a better job of removing hard water deposits.

The whole area in this part of the state has hard water and even cleaning the toilets very regularly the hard water stains have been impossible to get out. We have tried so many cleaners and the toilet is clean but the stains remained. We tried the pumice stone and it got out the hard water stains completely. It does take a little time initially but it got out the stains cleaners could not get out. I saw some pumice stones without the handles and I am glad I got the one with the handle.
