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!

When you mix citric acid with these alkalis,
does it foam up?

For small projects lemon juice and salt, and a brush to apply to project (I use for slightly rusty weaving reeds).
Molasses and water - for a good soak - needs to be the molasses from the feed store rather than the grocery - maybe someone can supply a reason - must be something to do with how refined it is ?  This is better for archaeological projects - like the hammer that got lost in the garden

yes, but then it will be good to use.
