No contact cleaner works like DeOxit.

If you need a contact cleaner that won't damage plastic this is working really well.

I needed to use the guitar before the replacement cable arrived, so I applied Deoxit to to the connections on the cable, and it restored the cable to a perfect working condition

expensive but works

I've only used this on one application so far, and it has worked great.

However there are some DeoxIT applications where the spray can is wasteful overkill and besides this small container is easy to keep on my desk when I am working small items, and very handy to carry in my pocket when I visit one of the boys to look at their motorcycle issues.
