Concrete behind fried chicken restaurant

This is one of the most difficult things I clean quarterly. Trying to get the owner to agree to a more frequent cleaning. The back door all the way to the used grease bin is awful. The grease / tallow gets on the concrete and hardens. It just seems to laugh at caustic and heat. It eventually succumbs but it is a pain. Any suggestions would be welcome.

When you have grease like that potasium hydroxide in the liquid seems to work much better than the casutic beads.If you have some butyl sitting around you can add that with the pottasium hydroxide and you should be good.If you could scrape the heavy off that might help as well.
 
OMG! Don't know why I hadn't tried the potash before. Man it cut the grease like a hot knife through butter! I have not gotten that concrete that clean ever. We used potash butyl and Tsp downstreamed. Thanks for the nudge. I've always been a little afraid of the potash. After we finished I neutralized it with oxalic. It looked great. I could tell just downstreaming it with low pressure the grease was just coming right up before I even hit it with the surface cleaner.

Why You ask am I afraid of potash? Google "resomation".

"
Resomation is a greener alternative to cremation. It uses water, potassium hydroxide and steam heat to dissolve the body. At the moment there are only a few resomation chambers in operation in the world, all of them in the US - ours is at Mayo Clinic, Rochester, Minnesota - but there has been interest from several UK councils and cemeteries about installing them. It does offer people a greener option."

So I can at least say im using green cleaning methods ha!

Yeah I'm thinking this stuff (tallow / chicken grease) is so hard to clean off the concrete yet we eat it all the time. Must really be good for us. I guess I need to go drink a glass of potassium hydroxide to clean myself out !

What kind of dwell time?

I recently did a Famous Dave's BBQ that wasn't done in six years, Nasty! I laid down a heavy house mix, and went to refuel my machine. Maybe was gone 45 minutes with Re-setup, and it came super clean with 210 degree heat.

I'm assuming that if I hadn't left for a super long dwell it would of gave me problems.

For starters I use a plastic scoop you get at Walmart for dogfood which probably holds 3 cups heaping. I think I had two scoops potash flakes two scoops tsp and maybe a scoop of caustic soda was in my bucket before I started. Also maybe a quart of butyl in a larger 6 or 7 gallon bucket of water sprayed downstream.
That's as accurate as I can remember. ALWAYS neutralize when you put something that strong down.
