How do I clean plastic pallets?
I have 2 large (43x43) plastic pallets I'd like to use for some diy garage organization. They are covered with black grease, rubber ( they were used previously to carry old tires and rubber goods) , oil, dirt etc.. They Do not look like a regular wood pallet ; they have the top and bottom openings but the rest of the pallet is hard plastic honeycomb shapes... geometry nightmare. Some openings are so small they won't even let me clean with a tooth brush. ( In a just world...lol... I'd be able to pick them up and dunk them in a huge vat of magic cleanser) I have tried dawn& vinegar (i think I actually heard laughing in my head), then I tried Krud Kutter which didn't seem to do any better. I was surprised because the black stuff surely comes off on hands, clothes etc. (sorry about the photo... sun hasn't come up yet)
