Rust on BBQ racks

[LiveInABox]

BBQ had it's first outing of the year this weekend! BBQ is kept covered over the winter but even so, the cooking racks are covered in rust! Got round it by covering in tin foil and I've had a good scrub with a Brillo pad today to no avail! Has anyone got any advice or top tips on how to remove rust and how to prevent it (other than keeping the racks inside)?

if it is too rusty for a brillo, it is irrecoverable.

otherwise, you can clean with a green scourer, and rub with cooking oil (or burger fat) to protect the steel from damp. The grease will burn off next time you use it.

You can get rust removal gel, just paint it on and keep rubbing it in with a small wire brush every 20mins or so. Once the rust is gone just use water to rinse off.
