From Zita: With a stain eraser! But use it very carefully! Spotting erasers are available e.g. from master Proper. These things are really a brilliant invention - real all-purpose weapons !!
From muffin: Also, I find the stain eraser super. They are also very cheap in the drugstore, then stop by the master P. Also good for white shoes and the bags of nylon fabric, which are now everywhere to see. But beware: never apply on painted surfaces. So I ruined a freshly sealed parquet floor when I wanted to erase black abrasion from rubber soles.
