Can you use this to clean a chandelier light bulb socket?

Yes, but it's awfully expensive for that and probably overkill. Cleaning them out with rubbing alcohol followed by a light wipe of some sort of silicone-based lubricant would be much cheaper and ultimately, probably more effective overall, though if the actual electrical contacts are really bad, it would be helpful to use DeoxIt specifically on those - but don't waste it wiping out the whole socket with the stuff. Obviously, you should flip the breaker or remove the fuse before working on a chandelier no matter what you're doing with it.

Has anyone tried using this stuff to clean pcbs such as pc motherboards or pcm/ecm modules on a car?

Absolutely... I have used this cleaner for years to clean PCBs and motherboards and it does an excellent job. It's fast evaporating, but I always follow up with some canned air to blow it off and make sure it is completely dry before reconnecting power.

can you use this for turntable connections?

What type of connection(s)? If you are looking at connectors that has a little corrosion or debris on them then yes. I used this just recently to clean some contacts for for HIDS in my car because the contact was interment and it worked like a champ!

Can i use it to clean my MAF sensor conector?

The CRC website says NOT for cleaning MAF sensor itself. But just connector seems like it would be ok as long as you don’t get it on the sensor itself.
