Hey, I'm Steve Smith with Camper Van Freedom. Evapo-Rust removed a fair amount of rust from my hardware, but the work was nowhere near finished. I still had rust to brush away, difficulty drying the small parts, and poor results when I tried reusing the liquid. I would not recommend it based on that experience. The bottle in my purchased kit was thirty-two ounces. I poured the whole bottle into a plastic bucket and put badly rusted nuts, bolts, screws and wrench bits into it. Those parts had become wet and rusty. This was a removable-hardware soaking job, separate from scrubbing my van's fixed cargo floor. The basic process described by the manufacturer is to clean dirt and oil off the parts, fully immerse them, check the rust removal, and rinse afterward. My soak got a good amount of rust off, but definitely not all of it. The remaining rust still needed wire brushing and elbow grease. That did not match the simple soak-and-rinse result I expected from the advertising. For my wrench bits, finishing the job after the soak took a lot of time and effort. I also disliked the strong chemical smell and the residue on the hardware. I rinsed the parts with water, but getting every small recess and crevice completely dry was difficult. I saw rust returning almost immediately after that rinse. For my actual job, rinsing and drying became another frustrating part of the process. Reuse did not improve the value for me. After the first use, my liquid became thick and very dirty. When I tried using it again on other parts, it did a poor job of removing rust. The original promise of a simple reusable soak did not match the result I got. My full page compares WD-40 Specialist Rust Remover Soak and Metal Rescue as alternative soaking products. Those alternatives are there to compare; I am not claiming I used them or that they solved the problems I had with Evapo-Rust. Thanks for watching. I'm Steve Smith with Camper Van Freedom. My conclusion comes from the work left over after soaking, the rust returning after rinsing, the smell, and the unsuccessful reuse. Read the full Evapo-Rust review for that experience and the two alternatives. See you on the next project.
