Rust and Automobiles

Electronics had better be well sealed. Many years ago I brought a stereo to my home in Mexico. The circuit boards were eaten up within 18 months. My microwave oven here lasted about a year. (My neighbours have had their house for 12 years and have gone through five.) When I had a CD player, I found that the discs rotted in a couple of years.

On the other hand, I have had Sonos speakers here for at least six years without any problems.
