Grease stains on paintwork

Post by henryp » Tue Mar 11, 2014 5:39 pm

I always seem to have a problem with oil/grease stains on my car's paintwork, and would appreciate suggestions.

The problem is the mucky hands of MOT testers, AA men, etc. Once they've finished, there are usually hand prints
on the doors and bonnet where they've obviously needed to touch them, but which won't easily come off with car wash/water.
It's almost as if the stains have sunk into the paintwork (both original Reliant paint and later 2k (I think) resprays).
I don't want to scrub too hard for fear of scratching the surface, and usually use a light application of Mer polish,
but I think all that does is remove the top layer of paint. Eventually I'll be down to primer !

I do try to keep the car polished (Mer) to provide some protection, and try to act quickly, but that doesn't seem to be enough.
Is this something others have come across ? What's the best thing to do ? Does clay remove stain but not paint ?

For grease stains a good soapy wash or two generally will remove them. I get lots of greasy marks on mine and they seem to wash off easily enough.

now Sun tan lotion is the stuff that paint should be made of because its almost impossible to remove! I have found repeated soaking with a cloth soaked in vinegar will help soften the lotion and it can be buffed away.

Try using babywipes, there is something in them that seems to lift grease.

Any marks should ideally be removed as soon as possible, but it sounds like these have been there for some time?

That being the case, you may be in the situation where it has penetrated the upper surface of your paint and therefore a lot of questions need to be asked before you attempt anything that will reduce your paints thickness. I would strongly suggest that you turn to a professional in this case with the proper experience and insurance (happy to recommend - via PM - if required).

Everyone seems to be shouting about claybar at the moment, but please be mindful that this is only designed for removing particles embedded in the paint surface that have not been taken away by a wash process. Rubbing it over your car will cause marring, that is almost unavoidable, so other options should be attempted first.

If a standard wash will not remove it, have you tried a citrus based pre-wash (I like ValetPro, but others are available)? Or how about an All Purpose Cleaner at various solutions, starting weak (10:1) and increasing the concentration gradually until it takes effect? In this instance, spray the effected area, agitate gently with a soft bristled brush (a paintbrush will do) and leave it to dwell for a few minutes. Under no circumstances must you allow it to dry out! Then another spray of APC and wipe gently away with a long pile microfiber cloth. Then wash as normal to rinse away any residue.

As ever, without seeing the severity it is almost always impossible to pinpoint the correct action, but hopefully my general ramblings will be useful!

Brake cleaner is what I use - spray and quickly wipe off and the oil's gone.

Many thanks for all the suggestions.

And the correct answer is ..... wet-wipes. We buy these boxed by the dozen, and they are brilliant for so many things, I guess I just never
thought to use them on bodywork. Anyway, tried one this morning, and the AA man's dirty handprints are gone. Result !

Next try would have been White Spirit, as it works well for tar spots and it's the wrong solvent for car paint so I feel it's safe.
Brake cleaner's another in stock item too, but I'm not sure what solvents are in it, so would work quickly as suggested.
I asked about clay as I thought if left in place it might absorb stains like a sponge, but clearly it's the wrong thing in this case.

Brake cleaner is generally fine. It is a good fast evaporating solvent that I use extensively. It doesn't leave any residue. However, next show or local bodyshop supplier, get yourself a can of *fast* panel wipe.

I have heard in the past the use of TFR (Traffic Film Remover) as a good "clean-all" but have never used it myself. Probably what the local EEE car wash uses?

Glad you found a solution and yes, detailing clay is sticky and acts to grab and pull away any bonded contaminants rather than absorbing them like a sponge.

Phil - yes Traffic Film Remover is on the harsher side of car care chemicals and the £5 paint removers use it by the gallon at strong concentrations - hence they can strip the dirt off your car (and often the finish) in minutes. As with everything it has its place and I use it (at a 20:1 dilution) to strip existing waxes from bodywork prior to the clay / polish / sealant routine.

As always, working on other people's cars I will always opt for the gentlest approach first and build up from there, and I would of course recommend that others do the same in their own vehicles. But in the real world, people find a solution that works for them (financial, ease and speed) and will stick to it.

Caveat - beware using anything not designed for purpose too often for fear of damaging your vehicle's finish - if indeed that is important to you.

Panel wipe is good stuff (generally a dilute Isopropanol Alcohol). I use it to remove polish residues prior to applying a wax or sealant.

Bear in mind that any of these volatile chemicals will also dissolve any wax you have applied to the area, so always refresh that panel to maintain protection.
