removing soot

steve_29

Recently had a co worker get soggy soot on a finished concrete floor.

Is there anything any of you have used to be successful in removing the soot stains.

We tried quite a few different cleaners with no success.

thanks

This may sound strange,

But I've successfully used a couple different methods.

#1,Speedy dry rubbed in real hard will pull alot of it out, but the spot will remain discolored for a while.

2nd,(taught to me by the old Cemetary Dept. head in the town I worked in)Wet the spot(spray bottle on mist) and put a dry plaster of paris mix on the stain, and change it when the color of the powder shows.

He taught me this because one of his backhoes blew a line during a dig, and sprayed hydraulic oil onto a few nearby headstones and ground plaques.Takes a while, but the stain does go away. Good luck. Chris

Degreaser?

Have you tried a heavy duty degreaser?

The speedy dry method

That Chris mentioned works for us also . Have to do a little soft shoe to work it in and it helps if the surface is a little wet . Another choice is to use dry sand mix cement . There is a chance the cement will scratch up though . Gotta try that plaster of paris trick sometime .

yes we tried a hd cleaner... didn't even begin to touch it.

this stuff is like a tattoo...

hot oxegen - as in an oxygen torch

depress oxygen lever and move around the torch or the cement wil crack - you might want to wet it first - the oxygen should still oxidize the carbon into gas

my thinking is that soot is formed when there is not enough combustion oxygen - (first co forms and if there still isn’t enough air, the Carbon drops out of the combustion process completely and you get H2O and Carbon soot) so we reheat with enough oxygen and you get co2 - gas - make sure the area is well ventilated as you could get CO also

ps it's only a theory - you might just blow yourself up

you can always rent a pressure washer with muratic acid

Soot

I have used Trisodium Phosphate or a weak solution of Muriatic Acid with much success. Wear rubber gloves and goggles!

Tried Goop?

Best stuff in the world. I use it on my laundry, upholstery, carpet, everywhere.

Works great on nasty oil-stained driveways too. Spread it around the spot, and put some plastic wrap over it so it won't dry out. Let it soak for a while, then rinse off with a hose.
