stain on exterior paint

[bbig119]

I noticed a dried liquid on the back of our 2009 mini yesterday. My wife was a work and had the car in a parking garage when we think this occurred. I think when it rained a nasty mixture of water, oil/gas/whatever on the pavement, and rust from the garage structure dripped down through a crack or crevice and onto the car. I say this because the dried drops and drips have a rust/copper color that has an oil/gas sheen in the light.

I tried getting it off with some soapy water with limited success. I think I'll need something with a little more oomph, but I don't want to damage the paint on the car, and I'm really hoping that this hasn't done any damage to it already.

Any suggestions for what I should or shouldn't use.

Thanks

Go to Autozone and buy a cleaner wax. It will take it right off!

Start with claybar, that is designed to get impurities off the paint. I second what Crawford said, but pick up something like the Mothers or Meguiars claybar kits it comes with claybar, lubrication to keep it slick, and cleaner wax to finish. That should get it right off.

If it is still giving you trouble maybe bug and tar remover will work.

thanks. I did try the clay bar. It helped but didn't get rid of everything. I ended up using a bug/tar/goo remover which did the trick and followed up with a second wash and wax of the entire car today.

With I had time to clay the entire car but I wanted to make sure I got the wax done before the car got exposed to the sun and high temps.

Cool, glad to hear it worked. It's a good idea to claybar the car at least once a year. I typically do a big detail before summer where I clay, polish and wax, that typically keeps the car in great shape for a long time, then I put down another layer of wax before winter to keep it protected from the rain.
