Do a google search for chemical companies in your area. I did a search in Wimberly, TX and found this...Where can I buy Caustic at?
Didn't you get a stencil from Dale at Serendipity Metal? Have you been using it?Where can I buy Caustic at?
I read somewhere that potasium hydroxide solutions work better on organic grease than sodium hydroxide. Does someone have expirence using both and what were your results?
To be honest , you will have to scrape the majority off to the surface then use a SH mix and a HOT water unit
Yep, Caustic is the greatest! I had a problem dumpster pad with heavy grease buildup. Alexy is right, you may have to do some scraping depending on how bad it is. On the bad ones, I let the caustic dwell, scrape it, then brush it with a stiff bristeled scrub broom. You may also have to make a couple attempts at it. It may not come completely clean your first try if it's on there thick.
I buy 50lb bags of caustic soda beads, and it goes pretty far. I downstream it, but on bad dumpster pads I actually use a pump sprayer so it isn't diluted as much. Usually I use 1 cup per gallon of water, but sometimes sronger is needed. Just rinse alot afterwards.
Here's one that was pretty bad, now it's all clean (forgot to take the camera for the last pic). The second pic is after the initial clean and scraping. Took 3 attempts at applying Caustic and scrubbing. Last pic is a different one, but what they look like now.

I've used it on painted block walls, and painted dumpsters. I've never let it dwell long enough to damage the paint, but I'm sure it will if you leave it too long.Great pictures
What effect does the caustic have on painted walls? Will it remove the paint?
I've used it on painted block walls, and painted dumpsters. I've never let it dwell long enough to damage the paint, but I'm sure it will if you leave it too long.
I sprayed some this morning on a painted block wall in the dumpster area. Let it sit about 5 min., then pw'd off. Came very clean compared to no caustic.
