Since I consider the PB forum members to be some of the brightest folks I know, I could use a little advice.....I'm laying in supplies for next season's maple syrup production, and hit upon the idea of using food grade plastic 55 gal. drums for sap storage.

My problem is, the barrels in question held butter before I got em'. I have used hot water and Dawn dishwashing soap to remove the actual butter remnants, followed by multiple wash/rinses with more hot water and bleach. But, the barrels are still...slippery? inside, with residue.

Anyone have an idea what I could use to cut this stuff? Remembering, that the barrels are plastic, and I'm going to store a consumable liquid in them?

As of right now, my hands smell like butter, as do my clothes. When I walk in the house, the family complains of the "movie theater" smell...I'm suffering from a butter-induced headache, and I can't grip the Ibuprofen bottle tightly enough to get the cap off.

Any ideas?

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
