I would clean using WD-40 as that will also help to stop moisture setting in again.

Yes it should help clean up the contact points. Alternatively you could try a rust remover and a wire brush.

Can I use this in the socket for my relay unit.
My pug 306 has issues with the indicator relay. I've been told to clean the sockets (3 pin) to make better connection. Will this do the trick?

should be ok because it evaporates - but i have never used it "in" a socket. I guess spary it in then turn the socket upside down so any excess and dirt flows out, then leave for 1/2 hour to ensure its completely dry

I'd like to use this on the steering torque sensors on my Civic. Does this come with a spray straw I can squeeze past the steering column's rubber boot?

Even though its designed not to leave residue and dry quickly, to be on the safeside you should wait atleast 45 minutes before reconnecting.

I found when searching that the most common answer was to let everything dry for 30-45mins before re-connecting. Some suggested using a hair dryer to speed things up but I didn't fancy the heat/electric idea myself

Question
Will it remove the Green oxidation
i had some trouble with my electric windows due to some of that green colloured oxidation on the terminal connector.

i done a quick cleanup and got the windows working again but still have a lot of the green oxidation in the hard to reach places of the connectors.

will this remove this type of Green oxidation and protect the terminals in the future for this issue?

and will i need another product like a silocon spray to spray over the conector to stop this from happing in the future.

basically i want rid of the Green oxidation and will this product do it.

i really dont want to be pouring in a baking soda and white viniger mix into my connectors if i can help it, i know that baking soda and viniger works great on this type of Green oxidation battery terminals but not too keen on using it on connectors male and female plug and sockets for items such as electric windows.

thanks in advance

Hi, thanks for your interest in Halfords products. The electrical contact cleaner is designed more as a degreaser and will not remove the green oxidation. The product is a gentle solvent and doesn’t contain anything that will protect the terminal after cleaning.

The electrical contact cleaner is safe on most electrical equipment, plastics and metal. It would be suitable for cleaning electrical contacts on a mixer. Just make sure it's isolated from the electrics before use and it has fully evaporated before power is restored.
