Spray For Multi Pin Plug

[William]

What is the best spray to improve connectivity in an aging multi-pin electric plug. Don't want to put wd40 on it as it might make matters worse.

We 40 is good for cleaning off the pins.
To preserve use oil spray, like Brunox.

Are you sure william? Its quite thick and non conductive. Good on batt terminals- less so on multi pin plugs. personally i don't understand your reluctance to use WD 40 I would use that or electric contact cleaner which are alcohol based I think.

Careful with wd 40 on some printed circuit boards. It can do more harm than good so David King Electronics told me.

WD40 make a proper contact cleaner (with yellow top).

 

[William]

Ah ha - that looks more like it - thank you David

Easy Start and a cotton bud.

Old connectors can lose their shape and get too sloppy for a good connection. You can usually use a screwdriver or pliers or something to bend a bit of spring back into the metal prongs so they are tight on each other again.
I spray them with WD40 then use the airline to blow them clean

Stanley blade to open the spilt pin is a good way to improve connection, but they are so cheap it is often better to put on a new plug and socket for peace of mind
