I am trying to remove hard water deposits from a clear glass shower door. Will muriatic acid remove the deposits??
Asked by: Ann
Buy the generic version of CLR (Calcium, Lime, and Rust Remover) which is half the cost of CLR at home depot. Make a 1:1 mixture and put it in a quality sprayer. I have the same problem and this works great. Be careful--do not spray fixtures or if you do, rinse immediately.

can this product be used to flush a tankless water heater ?

can this product be used to flush a tankless water heater ?
Asked by: Ralie
This is a strong acid that will dissolve the materials used in some tankless water heaters. In other words, this acid may destroy your tankless water heater! Therefore I suggest that you contact the manufacturer and ask them how to PROPERLY flush/clean your tankless water heater.

Rated 5 out of 5 by from Like in The Old Days I was really surprised to see HD carrying this when I went to get chemicals to get my in ground pool ready for the season. It is the strength I remember from 30+ years ago, and it really works. This acid is 2.5 times more concentrated than what everyone else is selling, and I expect that the one box will last me the season. It does deserve respect, however. This acid will ruin your day if you get it on something important, like your body, so be careful and follow directions when adding it to water. (NEVER add water to concentrated acid!) That said, I've used it not just in the pool, but for cleaning humidifier pads, toilets, calciumed up glasses--it works.

Rated 5 out of 5 by from Excellent Product I bought this to clean stubborn urine stains in a toilet. I used 3/4 of one bottle. I made sure the toilet had a normal amount of water in it. Carefully but quickly dumped in the HCL. Kept bathroom ventilated and used gloves. Waited about 12 minutes, came back and flushed. I then used minimal effort to remove all staining and the toilet looked brand new. Highly recommended as long as you follow safety precautions.

Rated 5 out of 5 by from This product worked much better than I had anticipated I used this product to clean a concrete slab that was very dirty and stained. I tried to clean it with a strong pressure washer but the staining was severe. I poured the acid over 2 foot by 2 foot squares at a time and moved it around with a wire brush. the effect was amazing. When I hit the concrete with a hose it was perfectly clean. I wish I had known this before trying to clean with t pressure washer.
