Evapo-Rust Gel Rust Remover - 500mL

CRC Evapo-Rust Brush-On Gel is a powerful, targeted rust remover in a thick gel format — designed specifically for situations where soaking isn't practical and a liquid spray won't stay put long enough to work. The brushable gel clings to surfaces, making it ideal for vertical surfaces, hard-to-reach areas and large items like boat trailers, outboard motor components, railings, anchor chain, tools and outdoor equipment that can't be easily disassembled or submerged. For marine and trailer boat owners, it's a particularly practical solution — rust on trailer frames, winch hardware, anchor systems and deck fittings can be treated in place without removing components or setting up a soaking bath.

The brush-on, rinse and scrub formula makes application straightforward and allows easy inspection during removal to ensure rust is fully cleared before rinsing off. Non-toxic, non-caustic, non-flammable and free of petroleum products, it's safer to handle and use in the workshop or on the boat than many conventional rust removers. For best results, follow up with CRC Rust Block after treatment to prevent flash rusting on freshly treated surfaces.
