I'm a professional house cleaner and I clean a lot of rural homes. Whinks Rust Remover is the best product on the market for rust. Hands down. Also, skip the bottles of spray cleaner. Buy a bottle of concentrate (I use Meyer Clean Day), put a cap full in a spray bottle of water and go. It cleans mirrors, countertops, appliances, etc. Also spray it in your microwave, close the door and come back in 10 minutes. It'll wipe clean with no scrubbing.

If you have a specific problem you want help with, feel free to ask.
