I am stripping paint off several old cast iron radiators (with a gorgeous scoll patter on the fins) and I want to leave the finish "natural", just rubbed with oil to prevent the iron from getting a light coat of rust. Last time I did this I used Penetrol to oil the radiators. They came out great (and still look great 8 years later), but they gave off an oily smell the first few years when the heat came on in the fall. I would like to get the same great look with out the start-of-season smell/off-gassing. I'm looking for recommendations of other ways to "oil" my radiators that will have a similar look but without the smell. Several people have suggested gun oil. One has suggested boiled linseed oil. But none have actually used them on a radiator. I would be grateful to hear what you have tried and how it turned out.
I don't know about gun oil but if you use linseed oil they will sticky for a long time. I know someone that stripped and oiled his hinges with A-1 oil. they looked great but not sure how often you would need to apply the oil again.
agree with Lair gun oil, also olive oil, really any cooking oil. I would run some tests and heat up several types of oils on the stove and choose the one that smells the best or least.
Linseed oil is the best solution. It will take sometime to completely dry, but it is worth the wait! Check out solventfreepaint.com
