Cleaning advice

[DaveK]

I met up with some of our club members yesterday for breakfast prior to heading to the track. Came out from the diner and when I got near my car I see it's covered in some kind of fine white hmmmm crap. Turns out that right next to the car park they're insulating the building with spray foam insulation and it blew over everything in the car park. Everyone got hit and no one is sure how to tackle the problem.

The stuff is really stuck on, you can get it off if you rub hard but its difficult. I took my car to a DIY car wash place with a high pressure hose to see if that would take it off, it did some but there's still loads left.

My thoughts are that this stuff is essentially stuck to the wax. So if we dewax with something (the Adams cleaner stuff perhaps?) then the foam stuff would come off too? Kind of worried that in taking it off I'll ruin the paint.

Any suggestions would be greatly appreciated!

Thanks
