My landlord has been saying for years that he wants to replace my old fridge, but it hasn't happened and it's progressively getting uglier and uglier. Really, the entire door should be replaced, but I doubt there are any still laying about for the model, and for the price it would likely cost, I might be able to get an entirely new (used) fridge.
Anyway, the door has a lot of rust on the exterior. It's ugly. I know that it is possible to remove this rust and repaint the door, but the specifics of how to do that escape me. I get the general idea of sanding it down with sandpaper, but which grit? And how do I know if I've gone "too far"? And then when I paint it, what kind of paint? Surely not ordinary paint. Would it be better to just put some vinyl on top of it instead and call it a day? As cheap and as easy as possible are my goals here, as I doubt the fridge will live another couple years and I don't want to invest a lot of energy into this. I'm just tired of how ugly it looks.
There are products which kill rust. Sort of. One is called naval jelly. You could use some of that, and some 100 grit sandpaper to clean up the rust areas. And then just paint it with Rustoleum. Probably won't look great, but that's your low cost solution. Might look better if you did the roll on, not sure. But the spray on might be easier and cheaper.
