Crown Remover

Made my toilet flash like new

After emptying as much water as I can out of the toilet I poured a little bit less than a half a gallon down the filler tube and a little bit inside the tank,then let it sit over night. All of the calcium buildup at the bottom of the toilet bowl is now gone and toilet is not only flushing again but I do not remember it ever flushimg this good. Only con was my filler valve broke at the top, not sure if this had to do with the acid or this was just odd timing. Anyways $9, to fix the fill valve plu...

Muriac Acid + Pool = Lowers pH

Use this (vs the Pool Muriac Acid at Lowes) - stronger/a bit lower price - though, less volume. Works well to quickly lower pH. Obviously, its acid and strong stuff and has fumes, so always wear safety gear.

Used for pool

Works great to bring ph/ TA down in a pool. Cheaper than exact same product advertised for pool use. Use caution and follow directions

It works great.

It works just like it should. So many products are so diluted and bland that they hardly get down to cutting through stuff. This has plenty of applications. Use your imagination and even clean glassware.

Great rust remover for steel

Pour slowly into water, about 50/50. Removes mill scale and rust.. Frank

You won't be disappointed at this purchase.

When I flushed my toilet, the water drained slowly and didn't drain everything from the bowl. I got a great tip from a YouTube member, Frank Sweet, regarding the Muriatic Acid. It works! Muriatic acid not only got rid of the toilet stains but also fixed the flushing problem. Warning: Be extra careful and follow instructions to the tee.

When u have a sloppy tile guy...

Our tile guy normally does great work but on this last job he was messy. Left a lot of grout smeared on our charcoal grey tile job in the master bath. The cleaner couldn’t get it clean until we bought the muratic acid. Whew is it strong. Make sure u follow the directions and work in a ventilated area. Does the job though.
