I have a fairly new electric lawnmower that works great, however the last time I used it it ended up going through a big patch of poison ivy (which I ended up covered in). I don’t really want to use it again if I’m just going to end up itching for 3 weeks again. I know the oils from poison ivy can hang around for years on anything it touches, so is it ok if I hit it with the pressure washer to clean it off? I don’t want to destroy the mower. If I just duct tape the battery compartment closed will that be ok?
