Might have to swing by and pick me up a gallon or 2. You using that on the rusty mud ring at the bottom of brick houses? Its everywhere around here
yep, but works. I generally use it straight or barely diluted.

Occasionally, but I rarely clean those, either behind bushes or people still donāt have grass and could care less, lol.

I totally understand Rick, Yāall use it for different jobs, ours is 20% across the board with 20% of sulfuric added in so says the sds. We run it @8:1 in a poly for for general use and 30:1 through our 5.5 machines. We need it hot to save money like yāall do SH so we can dilute the hell outta it.

I can tell you this about hydroflouric acid: It WILL MESS you up, even kill you in too strong concentration. Iām glad that most chem dealers limit their liability exposure by diluting it to under 5%.
The other thing is this: you can putz around trying to spray away rust stains with a pump up, going back over and over to get a little more to dissolve. OR, you can hydroflouric acid in a wheel cover brightener and watch that stain VANISH!

I just buy whatever is available. Pressure Works is local and have one thatās pretty good, but a buddy of mine buys truck wash for the acid application of the acid/base process of fleet wash and itās a bit stronger.

I have been using One Restore, F9 BARC, and F9 Efflo for a few years now. I am a big fan of F9, but unfortunately I cannot get it locally.
I cleaned the inside of a car wash couple months ago and picked up 5 gallon jugs of Hotsy aluminum brightener locally. Their product does not have any hydrofluoric in it. The bulk of it is 23% sulfuric acid. It worked fantastic at full strength getting all of the road grime and carbon deposits off of the walls (I tried diluting it, and it seemed like the waste of time, I donāt like diluting many chemicals, because it seems like they donāt work nearly as well, or at all, or I have to spend more time then it would cost to buy more chemical).
Reading through this thread it sounds like it may work great for rust. Barc is fantastic for rust stains.
I did some concrete brightening using one restore, and had to use the barc for a couple rust stains. After treating the already brightened concrete (using one restore,) I found that in the couple little areas where I had to remove rust, that the concrete was significantly brighter from the barc than it was the one restore. Iāve done multiple concrete brightening jobs since and believe that the barc is superior to One restore for this purpose.
It seems that the one restore, barc and efflo are very similar to what they do, and in my limited experience with it, I feel like the aluminum brightener is as well. My questions are:
Would sulfuric acid brighten just as well as F9 barc (Iām going to do a test on this soon, but curious of other peoples experiences)
@Racer for the red mud clay stains on the houses, I know you swear by one restore. Do you think that the sulfuric aluminum brightener would work just as well? I know not all aluminum brightenerās have the same chemicals, so here is whatās in my locally sourced containers:
2% Ethylene glycol monobutyl ether
10% Ammonium bifluoride
23% Sulfuric acid
What other advantages would one restore, barc and/or efflo have over sulfuric acid based aluminum brightener?
Would you consider using sulfuric acid straight undiluted on old concrete and sell it as an acid wash? I really like the way the barc makes the concrete look as it gives it this really bright white, almost ice blue look. Removes all of the dingy yellow.
I guess what Iām getting at is if I could use this aluminum brightener for rust, brightening concrete, red mud stains and efflorescence removal? It would be nice to just have one product that I can buy in bulk locally. Just not sure if there is specific advantages to getting the other onesā¦
@Seandz ,pick up some hydrofluoric based aluminum brightener, works way better on rust stains, any good pressure washing distributor should sell it. We get ours through NW chemical out of Washington state. His name is Dave Roberts , ask about the product called hurricane or typhoon concentrate. 8:1 through a pump up is amazing, we downstream it at 20:1 for our 2 step process.
Hydrochloric acid or AKA muratic acid is what the concrete guys use or weāll use to emulsify concrete on a concrete truck thats been hardened, and it removes rust , I wouldnāt suggest that because it liquefies the concrete with a long dwell.
Also proper PPE is your friend when using this stuff

Iāve only used 1 gal of One Restore in my life. Keep a gallon on truck because it has some multi-use. I use Aluminum brightener made locally I get at $8/gal for mud, fallout and oxidation removal. Still mainly F9 for anything more than lite rust.
