CRC QD Contact Cleaner 03130 – 11 WT OZ, Plastic Safe Electronics Aerosol Cleaner, Suitable for Sensitive Electronic Equipment

Q: The contacts on my car's turn signal bulb holder are corroded with intermittant contact. Will this correct the problem?

It most likely will. The contact cleaner is non-corrosive, so it certainly can't make it worse, and I have used it to successfully wash off corrosion on other electronic items.

Q: Does this cleaner work on volume and tone controls or potentiometers specifically?

This will work for this purpose, but save yourself some money. WD-40 works well for cleaning potentiometers and you don't run the risk of destroying plastic. Just don't use WD-40 or contact cleaner on linear/slide potentiometers. The chemicals dry up the lube and turns it into a glue. They will never be the same. I was a bench technician for many years and WD-40 is what we used most of the time.

Q: My husband dropped frappuccino on car floor. Some splashed onto stereo speaker in door panel. Is this safe to use?

NO! Never spray ANYTHING on a speaker, even when it's covered by a grille. This product is for cleaning metal electrical contacts... ONLY... (and it works well for that purpose). If you spilled something on the speaker, you can clean the grille by dampening a rag with 409 or a similar cleaner, being careful that it isn't wet enough for ANY liquid to get thru the grille. Liquids destroy speakers (by warping the cone)!

Q: Can u clean vizio tv screen with this cvc contact cleaner

I would not suggest using contact cleaner. I suggest using Plexus or a non ammonia based glass cleaner like what is marketed for being safe on windows having solar window film.
