Our five year old LG washing machine started rusting last year, under the detergent drawer. Initially I treated this as the start of an inevitable, unstoppable process of decay, but I decided, instead, to see what I could do about nipping the rust in the bud.
I went to Home Hardware and picked up some sandpaper, some painters tape, and a can of glossy white rust paint. I stripped the rusty area down to bare metal, finished cleaning it with vinegar, and then masked the area with the tape and plastic.
The spray paint took a bit of getting used to, and I started off painting much too close, but I quickly learned my lesson. I ended up applying three thin coats, 20 minutes apart. I removed the tape while the paint was still tacky, and then waited 48 hours before reassembling the washer.
The result isn’t gallery quality, but it’s satisfying nonetheless. And the rust is stopped in its tracks. I’m hopeful that I’ll be able to get more than the 7 years we got out of the last washer.
