So how did you get rid of the wax? I was inoculating logs a year ago and the jars are still waiting for clean up.
TIL, thanks!
See the boiling water brother comment.
The benefit of using oxalic acid for cleaning, apparently, was discovered as part of the process of cooking rhubarb:
They're now stocked in most of the big chain supermarkets, but it's a "reformulated" version of Bar Keepers Friend using Citric acid instead.
It's completely and utterly useless at cleaning the things the old Oxalic acid version worked on. :(
With careful perusal and emailing via Ebay though, the original formula stuff can be found.
This is the seller I get it from: https://www.ebay.com.au/itm/231989692018.
I'm not affiliated with them in any way.
