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 5.0 out of 5.0 by Acidburn5 Good but be careful
This acid is best for pool maintenance. It is hard to use as the bottle neck will cause acid to splash on you. Be very careful when using.

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 4.0 out of 5.0 by SMRDAL Works well - needs better design of the seal under the cap
Works well to bring the ph down in the pool. I have a new plaster so it takes quite a bit of acid on a regular basis to keep the ph in the recommended range.
What is not good with this product is the way the seal is under the cap. It does not come off nicely like other similar chemical cans and the plastic makes it hard to dispense the product easily. Should be an easy fix... Five stars if the seal is redesigned!!

Rated 5.0 out of 5.0 by Snoids 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.

Rated 5.0 out of 5.0 by Will way better than dry acid/pH- for your pool
One gallon of this brought the pH of my 22,000 gallon pool from 8 to 6.5 in 24 hours. More cost-effective and easier on the equipment than the dry acid (pH-) also found at the store. Also a few coins cheaper than the L pool store here.
