I took the time to try this out. The citric acid was purchased from the Bulk Barn here in Calgary for ~$25.00 for 1 pound (454grams). I used Arm and Hammer baking soda for my mix. (I actually used "used baking soda" that was in my fridge. Swapped it out for the new box.)
Made a small 0.5 litre batch as per the video.
These items were found in the ground while metal detecting over the summer.
I would say this potion is very effective. I put everything in yesterday evening for about 3-4hours. The small pliers where removed last night. I should have removed everything last night. It was all looking pretty good.
This afternoon I pulled out the punch and the sockets. You can see the punch has a fair bit of pitting on it now. I didn't see that on the punch last night.
All the items were placed in the solution as they were found. The pliers I had sprayed with WD40 to see if I could get them to move. I never cleaned the WD40 off....just threw them into the solution.
Cheers,
