As I was waiting for my poorboys to arrive, I foolishly put blackmagic tire spray on my tires. I waitied 20 minutes and still got splatters that have stained my splashguards with splattermarks. Washed it 2 times but to no avail. I have a 2010 white g37x. They look like little brown spots....What to do?

 

try some of this

this stuff is rediculously good at getting crap off...also, in the future I would wait way more than 20 minutes to drive after applying tire dressing. and try using a lot less. A little goes a LONG way
