Rust removal

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.

Hello fellow rust removers. What ever happened to DrX. That formula worked so well and also was biodegradable, non-corrosive. Gloves were worn to keep away from the rust not the chemical. I have tried the Beyond Balistics formula. It works well for dipping things.

First I made a one liter with washing soda. Fomula 1.

Second, I followed the same recipe with lye or caustic soda. Formula two.

Third. I combined the above two formulas in two liters of water. Wow, that was much more effective. 30-45 minutes dipping  time for clean metal.

Getting back to DrX. A person could de-rust a project car just by spraying the project car with a pump  bottle. I tried doing this on rusty wheels but the power washer was not up to the task.

I will try again with a new power washer rated at 4300psi. I will also continue to see if there are advantages of combining the different recipes together.

I wish someone had an old bottle of DrX that I could take to a lab. LoL

 

Warehouses Overstock claims to have it. Notice the product claims to be environmentally friendly.  I have no idea what that means. I cannot find what it is made of.
