So my  beloved backyard poplar drops the most obnoxious seeds. Green goo
that gets in  the kids hair.  What's the best way to remove? The guy at the
car wash  said to use methyl hydrate (lock de-icer??) but that it removes the
finish.  Which you then replace. Sounds dangerous. Any better  suggestions?

Thanks
Jeff

poplars dont drop anything that cant be washed off with soap and  water.
if your talking about real sap..like from a pine tree.. then paint  thinner
or mineral spirits will take it off without damaging the paint or  clearcoat.
use an old cotton sock or rag.
