Alcohol 70% is a NO NO it’s water based.
I recommend CRC quick drying Contact Cleaner
to clean contacts such as RCAs USBs, Speaker Cables spades or bananas
even electric plugs. Use cleaner first and then use Gold DeoxIT.
Happy Listening, Jim
Preferred Contact Cleaner and Contact Enhancer for Audio?
I have been doing some research on the topic of contact enhancers. I've used the Stabilant 22A contact enhancer. I understand other options occur in this space, such as the Furutech Nano Liquid, the Mad Scientist Audio graphene contact enhancer, and Cardas Contact Conditioner (to name a few). Any one having experience with any of these (or others not mentioned)? And what about contact cleaners? Are any contact cleaner worth considering (beyond 70% isopropyl alcohol)?
