A little more info could be helpful.

primer? oven cured? water based? manufacturing macine? new? old?

I've seen assemblers wipe off oil with rags and a degreaser. On new equipment before it was shipped to the customer.

Virtually any organic material such as oil can be removed by an organic solvent.

Mineral spirits. Available at any hardware store, even Wal Mart. Naptha. It is used to remove even silicone from automotive paint surfaces prior to painting.

I work out in my garage alot on old cars, and inevitably by the end of the day may hands and arms are black with old oil and grease. I used to use Lava brand soap or orange oil based soap, but one day I found I was out of it. Searching for something to use I spotted a bottle of Dawn dish detergent. On the bottle (here in the US) it clearly states "Takes Grease out of your way!" I laughed, thinking theres no way it could all be so simple. It worked perfectly, and to this day I use dish detergent to clean up grease as it works the best and is a hell of alot cheaper then those other products. I just take the liquid, rub it in, and rinse. And since dish liquid if formulated to be gentle, you should be able to use it on just about anything. It also makes a great spot treater if you get grease on your clothes (just use a little though or your washing machine will foam like crazy)

Note that the ONLY detergent used (and approved) by the International Bird Rescue Research Center (IBRRC) is "Dawn". This can be verified by going to: www.IBRRC.org

Any of the commercially available water-based industrial hand cleaners. Do not use solvent based cleaners as this will take off any clear coat and possibly paint if harsh enough. The hand cleaners take off all types of grease and oil when I am working on my vehicles. Try these they are cheap and easy to use.

Good Luck

In my industry we use Simple Green cleaner (diluted with water) then scrub with brushes and rags to get the heavy stuff off of painted steel. This is not a solvent, so it is less harsh on the paint. You also don't need a respirator, and there are no flammability issues. A final wipe with this "PF145" alchohol gets it super clean in the end, but that requires a respirator and absence of heat sources.

I recommend using PowerGreens H2Pro Cleaner/Degreaser. It's a green cleaner that actually breaks down grease and oils into their base fatty acids and allows for a better cleaning with no residue. Place parts in aqueous solution, agitate or scrub, then rinse clean. I would also recommend blowing off the part to remove all excess water. This will get oils and grease off in a safe manner without the worry of solvents, voc's or other toxic chemicals in the mix. Check it out at www.thepowergreen.com

You can use a non-phosphate based degreaser. You can purchase it from any company that provides pressure washers.

You can dilute it and wash the parts using a rag.

Don't use the pressure washer itself, you might start peeling the paint but the degrease is strong stuff.

I used to paint cars, and i always used a product called PREP-SOL. It removes oils and even silicon wax without harming the paint. Available anywhere they sell automotive paint products.

I don't know what the OP is painting but I figured what better to go with then something used on automobile finishes. Everyone is touchy about the paint jobs on their cars.

Prep-sol is predominantly Naphtha. Auto paint industry companies package it, rename it and triple the price. It also goes by the name Fin-L-Wash.
