If you own a roto, 3 stage ethanol buckets.
Leave used glass and tools with oil inside first bucket over night, doesn’t have to be full just enough to cover the top of said items.
Second bucket is for rinse off from first bucket and third is the final quick wash.
As the first bucket gets dark and saturated, start rotating buckets. Replace 3rd with 2nd etc. simply throw the used saturated dark ethyl into the roto to reclaim and re use again. Will give you decent crude if you want to collect enough for a disty run.
