I personally wouldn't. The best thing you can use for caked on grease/crud is paraffin/kerosene and either a cloth or a green nylon pan scourer, (if you want a bit more cleaning/scrubbing action than a cloth alone), coupled with some elbow grease. Paraffin/kerosene is not detrimental to the paint nor metal in any way or form either, so no problems with flash rusting, paint removal etc. You can also use white spirit/mineral spirit, but that's not quite as effective at cutting through grime as paraffin/kerosene, IMHO.
Concur......well said, Mr Fretters........ : )
Its not often one finds a piece of older equipment on which the original paint finish may be cleaned and preserved......but its a nice feeling when one may see the original finish, very nearly as it looked when new, many years ago.
Scrubbing gently with a mild solvent, such as paraffin/kerosene, and the least 'gritty' sort of kitchen scrubbing pad is a tedious job, to be sure, but worth the time/trouble if you like 'preservation'.
After cleaning away all the years of grime, the original paint may have a 'dried-out' look. Rubbing the paint down with a good preservative oil (I like the 'Break-Free' brand sold as a weapons oil) and a soft cloth, the softer the better, will bring back the lustre, as nearly as may be.
