Help - stain on karndean floor

[AllOfTheDwarves]

I've just moved some furniture to find a stain on the floor - it looks like the dye has leached out. I've tried the usual kitchen sprays but no success. Google suggested acetone (didn't work) and hydrogen peroxide and baking soda (also a fail). Does anyone have any tried and tested methods please? Thanks.

Have you tried the Flash Magic Eraser? I had black scrape marks on my white/grey Karndean flooring from builders dragging the oven and washing machine across the floors and it came up great. But it might have bleach in it so perhaps test an inconspicuous corner first?

Not very helpful put the furniture back.

I take it you’ve tried the actual Karndean remove cleaner?
