CRC Industries Evapo-Rust Heavy-Duty Rust Remover 1X1GL

Very dependable. It removes rust without damaging the underlying metal. My steel legs for my champagne bucket had rusted over the years, and as usual, CRC restored them to a lustrous finish.

Used Evapo -Rust to remove rust from a very rusty old car gas tank. I drained the gas, cleaned the tank, and poured a whole gallon of Evapo-Rust into the tank. Over about 3 days I propped up the tank on each side so that the Evapo-Rust covered all areas for at least 8 hours each. When I was finished there was still a very small trace of rust but no where near what I started with. At the end of the 3rd day I strained the used Evapo-Rust through cheesecloth ( a huge number of iron chunks filtered out) and still use it today on other rusty stuff. Great, safe product.
