I've found certain plastic handles on screwdrivers and chisels had mildewed right next to others that did not.
This Snap-On cast polyurethane dead blow hammer was buried under some other stuff in a damp cellar for a long time.
The surface was covered completely with green/white mildew but what surprised me was the wide cracks in the handle,
The cracks were bright red with no mildew down in the cracks below the outer surface like some science fiction shit.
Then it crumbled when I tried to pick it up, very strange, never seen anything like it.
