pontoons
- Aluminum pontoons on pontoon boats accumulate Algea, zebra mussels, etc and become badly fouled in one or two seasons. Low Odor Muriatic Acid cleans em up very well. Apply with pump up garden sprayer (all plastic) and wash off after 5 - 10 minutes with water or pressure washer. Very expensive cleaners are sold for this same purpose and do not work any better. A light breeze is good to keep the fumes away. You dont want to breath them.

Encrustations on old coins-
- I collect and restore ancient coins (bronze, copper, brass). Sometimes when I obtain these from find sites (i.e., Israel), with heavy deposits on them. Muriatic acid removes the deposits from the coin, without destroying or damaging the metal surfaces underneath. Soaking the coins in 25% solution to water (type of acid found in pool supply stores), works fine.

Many Uses
- There are many uses for hydrocloric acid. High concentrations of this substance can be fatal if ingested. This chemical should be handled with extreme care and kept away from children. Hydrocloric acid is useful or many cleaning situations and can be used to dissolve many things. Dilution seems to be the safest way to make this substance applicable to many application, such as work in the lab or household chores. Always handle with extreme care!

Question
- What I really want to know is would this dissolve a human body given a long enough period of time?... Just kidding! xD (No seriously. Will it? Kidding again... Or am I?)

Use with care...
- I'm used muriatic many times for home-made bombs. As well as being used for bombs, it will peel the paint off a vehicle (as i found out when a bottle leaked in the back of my truck), rust up stainless steel, dissolve aluminum, cause you to loose your voice if vapors are accidentally breathed, and can be very fun if used responsibly. The pure stuff is extremely strong, and will discolor concrete, eat skin if hands are not washed properly, etc, etc. I'm thinking it will take the paint off plastics, but it won't affect the plastic itself as muriadic comes in a plastic bottle... :)

Dangerous Chemical/Concentration
- Hydrochloric Acid is a poisonous substance and at lower concentrations it can be almost harmless to the skin (still dangerous with regards to ingestion/eyes, etc.). But at a concentration of 34-36% - YIKES!!! I would be careful in my chem lab with specific equipment - but would NEVER have it in my home....especially with a 2 and 4-year old at home! I'm with Are You Kidding!!!

Blocked rain drain about 50 feet long
- My drain from my downspout is a bout 50ft under my driveway, it is blocked under the driveway would Muriatic Acid do anything for me?
- —Guest Jack
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.
