Hydrochloric/ Muratic Acid

I use hydrochloric acid using a 3:1 ratio with water (acid 3 : water 1). We just moved into a newly built house and the tiles in the bathroom are covered with grout, so I use the solution above to clean the grout off the tile. I also use the pure for of muratic acid to clean (with a sprayer) Iron off the concrete around my pool.

Make your own soldering flux

Dissolve pure zinc (eg, from a dry-cell case) in muriatic acid to make your own acid flux for soldering .. Several articles via Google will show how ;) Be sure to follow safety hints! NOT a project for kids!

I had some old muriatic acid setting in a room for more than a year. I noticed there was some crystals or something that looks like salt on the outside of the bottle. I wonder if it is in fact salt. And what is the best way to dispose of it???

Sometimes you just have to use it.

No Way: Some stains just won't go away with anything else. Like manganese stains in a toilet bowl (I've got mang. in my water and the treatment tanks don't get all of it).

mutiatic acid

I use muriatic acid or hydrocholric acid to clean the algea growth from the bottom of my boat. Be sure to wet the concrete well that,s under and around your boat or you'll end up with with a ghost pattern of your boat. Keep the acis away from grass and aluminum.

Cleans gunk off shower stalls, easily

It makes cleaning old shower stalls a breeze. But you have to be careful and wear gloves of course. Also, open a window before you start using it so you have proper ventilation. Now there's no need to try to endlessly scrub away stubborn gunk. Muriatic acid is the way to go when you have tough cleaning jobs.

Are You Kidding?

Seriously? I wouldn't have that chemical in my house or my garage! It's too dangerous. What if a kid or a pet spilled it or something. There have to be better chemicals to use than acid.

I use muriatic acid to clean the yuck off of concrete. It's also good to prep it for a sealant or other treatment.
