Prueba final contra el óxido, Salfumant contra Vinagre

Drill brush: https://www.leroymerlin.es/fp/1155170... Drill stand: https://amzn.to/3SwBLJG In the previous video, we tested a series of products to see how well they removed rust and cleaned old grease. Two clear winners emerged: first place was hydrochloric acid (Salfumant), and second place was vinegar. This video aims to break the tie for the best homemade rust remover... We have three very rusty open-end wrenches. We're going to soak one in vinegar, another in hydrochloric acid, and leave the third unsoiled. Let's see what happens. At the Chinese store, I bought some lunchboxes, the kind used for sandwiches. We're going to fill each lunchbox half with water, half with vinegar or hydrochloric acid, and add a good squirt of dish soap. In one, we used hydrochloric acid, and in the other, vinegar, to be clear. And we're going to leave them soaking for 24 hours. The third key... well, that's a very 80s expression... The one we soaked in hydrochloric acid, the one in vinegar, and the one we left with nothing... we brushed by hand with a brass bristle brush, and then rinsed with water. And this is the result. If you're interested in the brush and drill stand, I'll leave a link in the video description. And by the way, please wear a mask...
