cglaeser 0 Posted May 23, 2016 I have an alarm on my mailbox. I use a Honeywell Ademco wireless door/window magnetic reed relay alarm and it works great with one exception. After two to three years, I have to replace it, apparently due to the nightly condensation. There are several sprays on the market that are designed to protect electronics from moisture. Does anyone have experience with these sprays? Can you recommend a brand? Share this post Link to post Share on other sites
