cleaning old dirt stains of plastic

[Emma27]

DS plastic step that he stands on to reach the toilet has got ingrained dirt over it. Any suggestions for removing it?

Make a slurry of bicarb and water, slough on and leave for a little while. Get a plastic scourer (or nylong stockings) and rub off. Elbow grease is the best.
