Old-timer told me to use silicone spray on every contact and I laughed
Honestly, I thought this guy was just stuck in the past. He's been installing alarms since the 80s and swears by silicone spray on door and window contacts. I always used the fancy dielectric grease the supply house pushes. Well, I had a job last week in a dusty garage and three contacts started chattering within 2 days. The customer was pissed and I had to go back and swap them out. On a hunch, I cleaned the new ones and hit them with silicone spray like the old guy said. Not a single false alarm in 5 days now. Maybe he's not so outdated after all. Anyone else have an old trick that actually works better than the new stuff?
