I bought my can of electrical contact cleaner off of eBay.
It was advertised as: "Max Blow Off™ #2053 Electrical Contact Cleaner 4 oz"
Well worth it. It fixed the air pump buttons and the radio buttons on my 83 Aspencade AND my neighbor's non-functioning starter button on his BMW.

Be careful with overspray. I used the Radio Shack "Control Contact Cleaner and Lubricant" number 64-4315. It says safe on most plastics and my experience is that it has worked well on my switches. I also agree with the use of compressed air with the process.

The stuff i got on eBay did not hurt my radio, dash or fairing. It said "safe for plastics" on the can, and it was.
