I purchased years ago a great non toxic wash for my press, and I'm nearing the end of 10L jug. I can replace it but I would like to avoid buying through the US (no offense) so I don't have to pay for brokerage, custom or shipping (to Canada). I was searching the web on making your own wash. I was reading (I can't remember where) that they use a combination of Crisco and Seventh Generation Citrus cleaner. Has anyone heard of this combo? If so has anyone made it? what would be the proportions? the how to?
