Help using Caig cleaning products

Use each in the order they suggest (i.e. clean contacts first, then lube and preserve and protect). The key is to use each product SPARINGLY. The less product used the better.

Agree on USE SPARINGLY!!!
The cleaner is ok to use whatever way you want, but the others should be used only to coat the items with an invisible coating. If you can see it glistening wet, that is way too much to leave on, and that 'extra' will turn to crud soon enough. The superthin coating, on the other hand, will protect for a long time to come.
Using Q-Tips works better than the brushs with the bottle...

CAUTION! Be sure to use Pro-Gold X (extended temperature) for your tube pins and sockets. Don't use the regular Pro-Gold for this application.
