Hydrochloric acid for cleaning

[anth]

Hi everyone
I am looking into a product for cleaning powerheads and am wanting some advice on wether it is safe or not.
The product is a brick and mortar cleaner containing hydrochloric acid and some alcohols.

Here is a link to the safety data sheet

any help is greatly appreciated
Thanks

IMO - Hydrochloric acid is really strong stuff and may cause damage to your equipment. I have found that white vinegar works very nicely. Make a strong solution of vinegar and water and soak the item you want cleaned for a couple of hours. If the build up is heavy on the powerbeads, use the vinegar straight.

Muriatic Acid is another alternative. I agree that Hydrochloric Acid is just too harsh for many materials.

Muriatic acid IS hydrochloric acid just with a different name.

Vinegar is known to gradually eat away at plastic and can cause your power heads to wear down and break prematurely.

Citrix acid is what most people on this forum use as it’s safe and effective.
Hydrochloride also works, just be safe and use precautions like gloves, glasses etc.

Citric Acid from BRS is what I use.

Muriatic acid is diluted hydrochloric acid. Same stuff.

It should not contain the other stuff you don't want. It can be had at Home depot here and I think it is sold to correct the ph of swimming pools at pool supply stores.

Use gloves

Citric acid also works. I just used it for the first time and it did well. It is a food additive.

Yes I get my hydrochloric acid from the pool supply store. A gallon is less than $15 and will last forever (unless you are acid washing rocks)

Thanks for all the replies
Muriatic acid was what i was looking for but as you say it is the same thing.
I am aware of the vinegar problem and have thought of using citric acid but dont want to leave my tank for a long period of time without the powerhead.
How long do you let yours soak?

I use muriatic acid for cleaning. I use a 5% solution for cleaning. I mix it outside. Also add acid to water and not vice versa. I use RODI water to dilute with.

Those two are identical chemicals.

It is not diluted hydrochloric acid. Those two names are synonyms, and neither name says anything about concentration.

True, well almost. Muriatic acid is a less refined form of hydrochloric, but typically not packaged nearly as strong as hydrochloric. If hydrochloric is indeed used, remember the old "A(cid) to W(ater), never W to A" acid dilution rule.

They are synonyms. Nothing more or less.

Both can be very strong (low 30's% HCl by weight) and both can be weak. I can buy hydrochloric acid that is far, far weaker than vinegar.

It turns out that most hydrochloric acid sold to consumers is sold under the name muriatic acid, while chemists and other scientists use the term hydrochloric. Not sure why marketers thing consumers like the muriatic acid name better.

There has been a recent trend to sell "green" muriatic acid that is diluted and fumes less since most hardware store uses can take the dilution. But you can still buy full strength muriatic acid from places like Ace Hardware.

HCL is hydrochloric acid. Muriatic acid is some dilution of HCL in water. That is the way I have heard it used. Sorry if it is wrong.

Whilst i have been researching the product in question i have found very conflicting information on the difference or lack of difference between hydrochloric and muriatic acid. This doesn’t really matter (for my use anyway) though as both are suitable for the intended task.
The product in question is a mixed hydrochloric solution with alcohols and such and i cannot verify wether or not all the content is reef safe. Im in the uk and the only way (i can find) to get hydrochloric or muriatic acid is to purchase it as a brick and mortar cleaner. Because of the uncertainty of the contents i have decided to just use citric acid as i can get this in food grade.
Whilst everyone has is here, would you mind sharing your mixture for citric acid powder and method for use of cleaning?

Thanks

It is definitely wrong. I suggest not repeating incorrect info.

Once again: there is no difference between muriatic acid and hydrochloric acid.

It is not a dilution difference, it is not a purity difference. Those are just different terms used by different people, with muriatic acid used more often to market to consumers and hydrochloric acid used by scientists.

Here's a food grade concentrated hydrochloric acid product from a scientific supply company that specifically says muriatic acid is a synonym:

Thanks for clearing that up.
My original concern was not with the actual acid itself, but the product i was looking into as it is labeled as a mixture.
Maybe you could take a look and tell me if it is reef safe for cleaning powerheads in a bucket (obviously im not pouring it into my tank) .

The ethoxylated alcohols are a surfactant ( like a soap or detergent). It likely carries the same concerns as a soap: not a problem at very low levels, but could be a concern with substantial amounts. Cleaning something with it seems like a low risk to the tank if it is rinsed well in clean water.

This shows the organic structure:
