Where to Find Muriatic Acid
Ask Danny, Concrete and Masonry, Kitchens and Baths by Danny Lipford
Danny, On one of your episodes, Joe Truini said that muriatic acid would remove scum and water deposits from tile in a bathroom. What I need to know is where can I purchase muriatic acid? - Denise
Denise,
Muriatic acid is used to remove excess mortar from bricks and to balance the pH of swimming pools, so it can be found at both home centers and pool supply stores. At The Home Depot stores it is available in the gardening department with the pool supplies. Muriatic acid is strong stuff, so be sure to read all the precautions and follow directions including wearing rubber gloves and eye protection. Dilute one part acid with five parts water before using and make sure there is adequate ventilation.
You can read and watch the video on Joe Truini’s method of cleaning bathroom tile with muriatic acid at our website in Episode 641: Bathroom Makeover.

I have a tile shower. Where the wall meets the floor, I have the ancient problem: Caulking deteriorates and wanter seeps below the pan, not to mention meldew buildup. I want to do thios right and not often have to re-do it.
I have been advised to:
1. Use grout and epoxy mixture n the seams. I can get it at Lowes.
2. Muratic acit to clean the tile scul.
Also, I have a few tile cracking at the threshold area, corners, etc so I am removing them, ibncluding the Duroc and thin set, and starting fresh in the threshold with net tile.
While doing this I want to redo it right and correct errors of past.
Any thoughts??

Check McCoy’s Building Supply or Ace Hardware last time I was at those two places that had it.

Check your local swimming pool store. They sell it by the gallon. It is less than $5.

Muriatic Acid is in the paint dept of my local Lowes store. I just bought a gallon for $6.98 today. Hope this helps.

I want to clean around the rim of a toilet. I also want to clear a possible partial blockage as the toilet only flushes COMPLETELY one out of three or four times. This makes no difference whether all liquid or semi-solid waste. I have asked whether just ANYONE can buy muriatic acid in New York State. I have heard about something called IRON OUT. Can you tell me anything about it?

Why has the price of muriatic acid gone up so much lately?
I put a pool in 4 years ago and used to by muriatic acid at Home Depot for less than $5.00 for a 2-gallon box. The las time I bought it I had to pay $8.99. I’ve also noticed that it doesn’t have the same strong smell that it used to have and it takes more to keep the pH in my pool where it should be. So it would seem it’s getting weaker as well as more expensive.
Does anyone know why this is or any more about it?

muriatic acid has gone up in price because of new hazmat laws and shiping is stricter.
it is weaker because of terrorist threat it is easy to make into a weapon.

For those who are looking for “muratic acid” to clean your toilet…why not just buy toilet bowl cleaner from the grocery store? “Muratic acid” (more properly known as hydrochloric acid) is already the main active ingredient of most commercial toilet bowl cleaners.
