I've been using CRC Electronic Cleaner for many years, never been disappointed, and always recommended! Today I had a contact failure on my 5-burner gas range. Position 1 burner would not ignite, however, I could turn on #1 and it would ignite with any of the other ***** turned to lite, (all ignitors operate when turning any **** to lite). That isolates the failure to the #1 switch, simply pull the 5 *****, remove 4 screws, and take the front panel off.
The only problem, the switch case is hot melted, and tandem with the other 4 switches, however, not sealed. Before cutting it open, I decided to pulled the #1 switch off the valve, grabbed the CRC and a towel, sprayed in every case seam, front/back and sides where the wires travel through. Gave it a minute to dry, then pressed the ignitor switch back on the valve, turned the ****, voilą ignitor switch works again!
CRC just saved me 50bucks!

 

I have said in other threads, everybody here should have a can of that stuff, these trucks are getting old. I have been using it for a LONG time. 50+ year old Oldsmobiles and motorcycles require some attention.

 

Just used some Deoxit for the radio in my squarebody and my old Kenwood receiver in my house. You are correct, everyone should have a can.

 

My 2yr old gas grill igniter stopped working, checked the battery voltage=1.5v. Grabbed my can of CRC Electronic Cleaner and sprayed inside the battery case. voilą igniter works again!
CRC just saved me another 30bucks!
