Rusty Microwave Oven Saved From Scrap-heap


When Houghton Regis News Desk posted a question from an anonymous reader, the readers responded in their droves.



The replies came flooding in. We have annonymized the responses here, to save any embarrassment to the original commentators, but these were the actual replies:


The challenge was on to restore the oven. First, an electric sander was used to sand away most of the rust. Then the areas affected were sanded further with emery paper. Next, two layers of surface primer were applied.


Next, two coats of a grey topcoat of Rust-oleum Stove and BBQ Paint with a heat-resistant finish was applied. Microwave ovens, in general, don't get very hot, but this one was actually a combination oven so it would be very hot sometimes. The actual colour wasn't a precise match to the original, but it was good enough.


Over a month later, the original rusty microwave, which incidentally was a combination oven, similar to a model sold in Argos for £90, the combi-oven is working as well as it ever did before. The problem was the build-up of steam during operations such as cooking baked potatoes. After use of the oven the door should be left open to allow the build-up of steamed water to evaporate. That will stop the steam getting into any small cracks and causing the metal to rust.



The anonymous reader said after providing the pictures, "I think we paid £9 for the top coat and about £6 for the primer. We had a sander anyway, and emery paper is inexpensive. But it's all been worthwhile. We're really pleased. The colour match isn't perfect, but the main thing is I can safely use the oven again, and it hasn't cost a lot considering what a new one might have cost. It certainly saved sending something to the landfill site. And we'll have to make sure that the oven is properly aired after use. "
