RCA cleaners

Hi,

There used to be plastic RCA cleaners--you'd put cleaning solution on them and they'd fit onto the RCA connectors on the equipment. They were white (I remember this because after cleaning, they'd come out black with dirt). The company that made them went out of business in the 1990s. Does anyone make anything like this now? There was nothing better (that I knew of) for getting into the RCA jacks on equipment.

Thanks!

Matt
