Cosmoline removal

Flat sixx · 10-18-2018, 07:59 AM

Hey guys I’m removing the cosmoline from my fenders wells. Did one so far with using brake cleaner and goo gone. It was messy and took two days for one fender. Was wondering if I just used a power washer would it come right off instead?

Why take it off?

I'd say it was highly beneficial that this stuff was on these cars back in the day when they were daily driven, driven in inclement weather, etc. Now though, most only see the light of sunny days and many get waterless / rinseless washed even. As such, I say adios to the cosmoline. Dry ice blasting FTW!...

It’s good evidence of originality, people seem to value that these days

I'm still waiting for that technology to make it to the Midwest. Still a lot of well known shops in my area STILL have never heard of this.

I offered to pay someone $5000 to cryo blast the entire undercarriage of my car if they could find a place to even rent out a machine. the shop wouldn't do it and said they don't think it's a hoax.

I tracked down places that offer the service, but use it on oil and gas company equipment... they thought I was pranking them when I asked if I could use them to clean the bottom of my car.

Got one fender done. Used a mix of break cleaner and goo gone commercial.

I used Chemical Guys Grime Reaper with a hand brush then wiped all the residual grime with Optimum No Rinse.

what about letting it soak and then using a pressure washer on a very narrow setting.
my PW about took it off my BMW without soaking.

I'd stay away from blasting these cars with high pressure water at this point, for fears of propogating the tin worm. Alternatively, I'd wanna be REAL diligent if doing so.

I scrubbed my 84 Targa front wheel wells using a water based degreaser to remove most of the goo then a brush with just mineral sprits (cheap paint thinner) and/or kerosene followed by the water based stuff again. I had the front suspension completely removed for rebuilding at the time.

No pic at the moment but I’ll look for the before and after.

This winter it’s rear suspension rebuild time, I’ll start when the salt comes out in Ohio

My father was in independent importer from 1962 to the mid 80's. A lot of VW's and Porsche's came through our hands. They all came in with a coating of cosmoline on the trim. As a young kid I'd spend hours helping clean them up prior to delivery.

We used kerosene. If we had access (depending on the port in Seattle or Vancouver) we would get them steam cleaned. Steam cleaning worked really well and was quick but it was more expensive than having me do them ;-)
