Product Reviews

  • "Outstanding cleaner for those corroded old contacts - no residue" by deniss on 4/3/2013
    Overall: 5 out of 5

    This contact cleaner is outstanding: it leaves no residue, and it really improves conductivity in old corroded switches, the kind you see in vintage audio equipment. I had one really stubborn rotary switch that I thought I would have to take apart to clean manually, but several generous flushes with this spray were able to cut down resistance between switch contacts to a fraction of an Ohm. For rotary potentiometers, I recommend using this cleaner first and then follow it up with a DeOxit spray to retain lubricating action of the potentiometer. This cleaner is also Made in the USA!

  • "Great product, great price." by thechoochlyman on 2/21/2012
    Overall: 4.5 out of 5

    It really gets the job done, and it's not as expensive as others cost.
