I posted the washing soda recipe in the washing soda
thread, but I thought I would post the alternatives here as well.
This is a chelating rust removal recipe to use like Evapo-Rust, but with non-toxic and less toxic stuff. Recipe comes from a cool Youtuber, who I forgot.
So for every liter of
water you will add 100 Grams of citric acid.
And one of the following:
Either 40 grams of sodium carbonate/washing soda
or 63 grams sodium bicarbonate/baking soda
or 30 grams sodium hydroxide/lye
May all your restoration projects run smoothly!
