ACID WASH – 65 poles – best ways???
I have to acid wash 65 galvi. steel light pole prior to painting them. The paint rep is not a font of good tips, so I will ask Breaktime. Someone has BTDT.
What is the best way(s) to apply an acid solution to an 8′ steel pole, then rinse it off. Mops, sprayer, sponge, wet rags, ???
Jobsite water is something of an issue. Some of the homes have it working at the front. We can get it, but not at every pole. I can fill a trash can and put it on a hand truck.

garden sprayer...
acid brush on a pole...
rise with a garden hose...
what type of acid???
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming
WOW!!! What a Ride!
Forget the primal scream, just ROAR!!!
We seem to be thinking alike.
acid brush on a pole...
We are trying a sponge mop. Seems to get it up and down the poles. See if the sponge is there tomorrow. Left it in the rinse water bucket overnight.
rise with a garden hose...
Our game plan changed. We have another 100' of hose coming in tomorrow. Copious amounts of rinse water seem to get the foam off. We are going to try a deck brush that hooks to a hose for the rinse.
what type of acid???
Yes, what is the stuff? Read the label, but without a degree in organic chem...
Some complex organic compounds and something like benz...sulfonic acid. Not just plain muratic. Adam thinks it's TSP with an attitude.

Hear ya, but the boss has ICI supplying this system - Devprep 88, primer, topcoat.
Since coating technology is not my field, I salute and get 'er done. Two coats of primer, two of black and the lights look rather elegant.

I like the sound of that TSP with an attitude, Gotta have something to cut the lubricant they put on 'em after they're galvanized. Jim
Plain ol white vinegar , straight, should do the job nicely and it's biodegradable. Hydrochloric(read Muratic) and benzene sulfonic acids will open up some serious disposal issues that you don't want to deal with, besides they're not cheap either. Crew safety is another issue. A little vinegar ,acetic acid, might sting like made but it's not going to leave permanent damage if it gets in the ol eye ball. Wear safety glasses and gloves just the same.
I'd love vinegar. What we do to pickle galvi flashing.
Crew has glasses and glove and such. We find that a common sponge mop works well. No dribbles out where the operator is standing.
Have 200' of hose and a deck brush attached for the rinse. Lots of water. I have a chap who has a lot of time with concrete stains and their acids, so he gets to handle the wash. The ToolBear
