The interior of my refrigerator has some rust stains that won't come out. What kind of white spray paint should I use to make the interior look better.

will need to sand down to metal no rust then primer then repaint --or spray or wire on a rust away product most auto or home stores carry it

Most likely not rust. You would see rust stains. IF you do repaint it, make sure that it is clean and dry. Oil or contaminates can cause the problem that you are describing.

Your question is not clear, what do you mean by fish eyed?

you can repaint the unit any color you wish, just be sure to cover the controls and the back if you decide to paint all the way around to avoid clogging any ports.

Get your refrigerator repainted before it is too late. It isn't that costly. Cracks may be due to rusting. Ask those mechanics about it when you give it for painting.

You can clean off using a green scrubbing bad and some brasso all at wall mart then buy a can of spraypanit and spray it with food grade paint by Krylon paints also at wal mart. The paint will seal it and keep it from comming off.

why is it rusting?

If someone could solve this problem forever they would become instant millionaires!!! (it is an ongoing problem with just about every vehicle forever (road salt and pitting from stuff that gets kicked up by tires, does not care what kind of vehicle it is) I generally use a product called rust killer. Just follow instructions on container. I have a Jeep (noted for rust there) I use rust killer, then cover the entire rocker with fiberglass, then spray the entire thing with bedliner coating. (if you need to match paint on car, just re-spray over it with correct colour)
The biggest problem is that the rust you see is not all the rust that's there...it actually begins inside the panel where you can't get to ...that's why it bleeds rust stain through the paint before holes appear.
Good luck! Hope this helps you.

oowwwww!!! thats what we call in the refrig biz "refrig cancer" the door itself is actually rusting from the inside out. the older refrigs used fiberglass insulation inside the doors which has a tendency to hold moisture, and overthe years rusts through. the new door use blown-in poly styrene foam far less likey to hold moisture. That being said you could remove the door lightly sand and paint, can of krylon enamal aint should do it, at least for a little while anyway

You may end up respraying the door, but here goes.-

First mechanically remove as much of the rust as you can with an old screwdriver or similar scraper. Then use coarse emery cloth - 80 -120 grit untill all you're left with is shiny metal with rust pits.
You may need to go out further than you think - about 1" all round.

Then use a paint- on de-rusting fluid from vehicle products supplier. When all rust is black or dissapeared, use a zinc primer on all the bare metal. (this will stop it reacuring)

Then either spray the area with an "appliance white" aerosol or squirt it into the cap, and use a paintbrush.

If you are spraying it, open all house windows and doors, cut a mask from newspaper- then tape it to the fridge. Use blankets , plastic dustsheet or old sheets to protect things, and spray it from 12" in several very light coats.

When done, "polish" with T cut - which should remove the rust stain too.

Seal the area of the original leak with a white or clear silicone - and sort the original leak out.

If you polish the plastic with a silicone spray, water will tend to stay put rather than seep.
