Option 1 … renew the floor-covering

Option 2 … treat it as ‘Art’ [unlikely to get away with that, methinks]

Have you tried Jif/Cif cream on a damp rag and baby wipes/Wonder Wipes?

It'd be interesting to know what the stain actually is. Looking at it, you'd think rust off a wheel rim, but you said it was just tyres you put down.

I got some rust on a nice old Formica-topped table once after leaving a steel oven dish on it for a few weeks; nothing I tried could get rid of it.

The rubber feet on a table-top power supply reacted here with a vinyl tablecloth in the same way. Not a surface mark, a stain deep into the material like a burn. So far nothing I've tried touches it, all the chemicals mentioned in the thread plus Sulphuric Acid. As the feet don't stain anything else, I think it's a chemical incompatibility.

New tablecloth needed.

If the stain has become part of the material then it may be possible to draw it out with a poultice with disclaimers that it damages the vinyl. Klingstrip is sold as a painstripper but I've used the stuff to renovate a filthy marble fire surround (sucked th dirt right out from deep in the marble and came up like new)and i use it to clean the kitchen grout. A small trial-size pack goes a long way if mean with it.. as in trowelling a thin layer along grout lines rather than the whole tile. Cover with clingfilm or old placky bags for12hrs+ (can be a day or two for stubborn stuff) and the wash off. I think it's a clay/alkali mix but it really does draw cr@p out

Searching Google for rubber stains on vinyl floors gives loads of results and tells me you are toast.

Gerry – this may help **LINK** but then again nothing is guaranteed

I know this going to sound mad but try brown paper and a hot iron. put paper on and iron over it, might suck it out.

Oxalic acid – obtainable as Y10 (a gel) from a marine chandlers, or as Bar Keepers Friend (a white powder, applied with a wet cloth) from a hardware store or ironmongers. It’s excelle all sorts of stains, nudging rust stains from Formica incidentally.

Correction, I see OP did try bleach.

Try Googling "Plasticiser migration". I think you're stuffed.

When manufacturing electronic products we used to have to be carefull how they were packaged to prevent the plasticiser from the power cable ruining the plastic case of the unit.

I'd be looking for some smaller tires and make some artistic and clever crop circle-like patterns in it. If you can't fix it – feature it!

(or get new rug)
