That looks like great pantry shelving Kathy! I have used some similar that I bought at Lowes. You should be able to get rid of the rust with a little scrubbing followed by Rustoleum paint. We have been working to get the garage items up off the floor and onto shelving. Emily is a big help to me. Wee are organizing the heck out of things out there! I could use those shelves right now!
That's funny because (for some unknown reason) I thought of you when I saw this picture!
