How to remove this stained?
 

Hey guys! i have this BRZ white and noticed this kind of stained on the body. Do you know the best way to remove it??

Depends on what it is... I would try a spray detailer like the ones from turtle wax with a micro fiber towel and carefully remove it, just b gentel cuz u dont want to scratch ur car

clay bar

or try using a bug/tar remover or an all purpose cleaner

Try a cleaner wax

I'd start from most gentle to buffing it if whatever that is ate through the layers T.T

Detail Spray?
All Purpose Spray?
Clay Bar?
If none of those work and since the area is very clean now...hand buff it to level it out...put sealant and be done.

heatgun and goo gone very carefully.
