QEW and Bird drpppings/baked on stuff

[Robb]

I had to leave my car out of the garage for a few days and when i put it back in the garage i washed it w/ qew.

My question is what is the best way to remove bird droppings and i also had little yellow dots that were caked on and tough to remove, i used qew but got some marring form being too agrressive. However i had to get somewhat aggressive or it was not going to come off.



So what does everyone here do to deal w/ that situation?



Thanks

In addition to eliminating the marring, you may have to worry about etching reappearing when exposed to heat and water.



I always approach bird droppings this way (http://autopia.org/forum/showthread.php?t=4009&highlight=bird)
