I was faced with this problem today -
Ten years ago my wife (in one of her painting furies) painted a radiator in the spare room with emulsion and I wanted to remove this but not the original radiator finish.
I did a search on here and found a couple of posts but none gave a solution which just removed the emulsion but did not remove the original finish.
I have just done this successfully using the following quick and simple method ............
1/ Drain and remove the radiator and lay it flat on an old dust sheet outside.
2/ Mix up a strong solution of ordinary household Soda crystals - about three heaped tablespoons to approx 300ml. of hot water and a few drops of washing-up liquid.
3/ Brush the solution over the emulsion paint and leave for 15-30 minutes (re-brush if it starts to dry).
4/ Pour BOILING HOT water over the radiator and then immediately brush with a stiff bristled paint brush.
You may need to do this step in a couple of stages - pour the boiling water over half the radiator and brush off then repeat for the second half.
This was just an experimental try but it seems to have been about right as the emulsion just lifted and peeled off as a skin(s) like magic leaving the original white radiator paint completely unaffected !!!!!!!!
Don't use industrial strength Caustic soda as that may well attack the original finish - just the stuff sold for household use.
The removed skins can be picked or shook off the dust sheet.
Hope this helps.
