I was able to get a quantity of 15 gallon containers from my brother. He got them from a neighboring dairy farm, and he used them to haul milk that wasn't grade A quality. (He uses the milk to feed to the pigs.)
The barrels are number 2 HDPE, and I've tried quite a regimen to clean out the residue, but some still remains.
I've used hot water with a strong caustic first, followed by a soak with vinegar. Next I soaked with a bleach solution, and lastly Oxyclean. In places where I couldn't reach with a brush, some of the white clumpy stuff still sticks. Any ideas?
