Ok so I've a general cleaning old motor bike engine parts question Id like advice on but maybe people have some great tips on other cleaning jobs to do with cars. Perhaps you've found the perfect ratio of diesel to pine handy Andy with which to clean your felt head lining spotlessly.. if so then post it here.
My query is how best to clean baked on oil off alloy castings on a motor bike engine. I've tried petrol and de-greaser but not much luck. I was wondering about using paint stripper but wanted to check it won't damage the alloy. Any ideas? If I was made of money and had more time I'd take the parts to a engine recon place and get them to clean it but I'd rather find a way I can do it myself. It's not terrible but since the parts are off I might as well try cleaning them.
Plus gearboxes etc when they get that oil stained look. Anyone here found something good to clean them with? Maybe something slightly alkaline?
