DIY Rust Remover Formula

[Dibbons]

Recipe: 1 liter hot water, 100 grams citric acid powder, 60 grams sodium carbonate powder (not baking soda) also known as washing soda, soda ash, sal soda, and soda crystals. When mixed the solution bubbles a little like sparkling water. It turns almost black during the cleaning process. I suspect that this formula may possibly mimic what is used in the product know as "Evaporust".

I made four gallons of the mixture to clean a couple of 340 intake manifolds. I removed the intake splash shield on one intake (the other was missing) and you can see the results in the photos after more than 12 hours in the "drink".

My internet cost: 2 kilos citric acid $22.32 USD; 2 kilos sodium carbonate $14.75

if you add sodium edta at rate of 2oz per gallon you will get pretty close to evaporust

I found this video a few weeks ago. Very scientifically done - no voice over, no look-at-me moderator, just the facts, ma'am. I opted for the vinegar, and it works well - I used the 20% vinegar instead of the standard 5%.
