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 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.
