Inadvertently i stumbled across a great tool to use Caig or any other mfgr products with, especially effective on RCA's.
they are Japanese Q-tips. You have to get them at a Japanese supply store. There are 2 kinds i've seen, both make our US made q-tips look quite ineffective.
the cotton is so bound to the stick that it won't come off, even when soaked in water for a while.
This year i've discovered both japanese Q-tips and Jap duct tape. both are far superior to what's avail in the US.
occasionally i run across this stuff when people leave things behind after a move-out of the bldg that I manage. the japanese always stack their leftovers in neat piles, and label everything so our staff knows what is what.
recently a friend went to a huge Japanese store here & found both kinds of Q-tips in the baby section. Haven't had any luck scoring another roll of the duct tape.
I used to use 99% rubbing alchohol on my inputs & outputs, but i just spent good $ on an aerosol spray of 100% pure...no clue if its any better, but at least this stuff doesn't have additives to keep folk from drinking it.
i like caig products as well...
