Its a HDPE 2 Tote said to be used for pharmaceutical grade fertilizer, but it had a thin sticky residue and some silicon like chunks. I had already pressure washed it and then noticed it after the tote was dry. I dabbed alittle paint thinner on a rag to test it, it worked so well I wiped the whole interior of the container.
So now I have paint thinner to worry about. I've read cat litter, soap, etc... Does anybody know if it is a losed cause?
