Personally I'd try Bar Keepers Friend

Ironically, here in Australia that brand has really destroyed its image.

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.

Always been a bit suspicious of that since it contains oxalic acid, which is toxic. I assume it's water soluble enough to get rid of easily before you use the surfaces for food though.

> oxalic acid

The benefit of using oxalic acid for cleaning, apparently, was discovered as part of the process of cooking rhubarb:

Definitely rinse thoroughly, with the exception of vinegar there's not a lot of cleaning products you want to be eating
