This recipe creates an effective rust remover that rivals commercial products like Evapo-Rust. You can make it as a liquid for soaking parts or convert it to a gel for application on vertical surfaces.
Perfect for soaking rusted parts that can fit in a container.
Per 1L of Rust Remover liquid:
- 200g Citric Acid
- 125g Baking Soda
- 900ml Distilled Water
- 10 drops of Dish Soap
- Fill up the container with 900ml of Distilled Water
- Add 200g of Citric Acid
- Stir until the acid has completely dissolved and the liquid is clear
- Slowly add the 125g of Baking Soda (warning: it will react strongly)
- Wait for the reaction to stop and stir until the liquid is clear
- Add 10 drops of Dish Soap
- You're done!
You can convert the liquid into a gel. The gel will make it much easier to apply to rusted parts that aren't easily submerged.
You will need the following items:
- 75ml Distilled Water
- 75g Corn Starch
Or, alternatively:
- Xanthan Gum
- Glycerine
To make the gel:
- Add your Rust Remover liquid to a metal pot and turn up the heat to a simmer
Then, if you're using Corn Starch:
- Add 75ml of Distilled Water to a cup
- Slowly add 75g of Corn Starch and stir until fully dissolved and you have a thick gel
Or, if you're using Xanthan Gum:
- Add a bit of Xanthan Gum to a cup
- Slowly add Glycerine while stirring until you have a gel
And finally:
- While the liquid is simmering, slowly add the gel while stirring
