A customer left logs at the side of his burner, soot damage as in images.

I  dry vacced, chemical sponged , then high alkali cleaner rinsed off, then "dymavate" acid cleaner, rinsed off, then Hydrochloric acid rinsed off.

The pics show the end result, any other ideas?

thankyou in advance.

I was doing travertine behind cooker that had only a bit of smoke on it and only polishing with hand polisher gave acceptable result.
Never tried diamond brush, if shine not required then might give some result.

Looks like the customer painted his burner insitu.

Thank you I will send some images tomorrow Kevin.

The customer rent the house and does not want his landlord to know that he has had a fire so is paying for it himself. The fire is wet because I took the image after just cleaning it. It has not got any paint on it at all.

Try the PSRP Poultice and mix it with Miracle Epoxy Grout Film Remover.  Apply it about 3mm thick and apply it in a small test area about 4" Square and then cover it with polythene and make it airtight.  Slash the plastic on top to allow a little air to dry it and then go back 3 days later when it is hard and remove.  If it has drawn the stain repeat all over.

didn't chemspec do a paint on latex for porous surfaces, you paint it on, leave it for a few days then you peel it off and its drawn the soot into the latex.

haven't got a clue if it would work in this situation though

They do

Lots of companies do similar products and they work well but they are all designed for pulling soot and dirt off the surface and just below.  But in tests we found Poultice mixed with the appropriate cleaner works better for pulling stains soaked in sub surface out of stone.
