Connector corrosion

[DSYKES5500 22]

Hi all,

 

Can anyone please advise how to remove the green corrosion in the sensor for the expansion tank?  I was initially thinking electrical contact cleaner and a toothbrush but thought someone might have a better solution?

 

Thanks!

I use nail file , or 500grt sanding paper folded in the shape of stick .. and contact cleaner spray .. scrub with the abrasive each terminal and wash off with contact cleaner , will clean up nicely .

Superb! Thanks for that.

Once it is clean put some Contralube 770 on it so it stays that way.

I used to use lemon juice . No joke. It works a treat

I'll try that Telf!  Thanks!

Back in the days , i used copper grease for the connector terminal protection after clean-up .

Isn't copper grease conductive?

 

Vaseline is a good alternative to Contralube 770 but I can't rate Contralube highly enough, all my indicators and foglights etc worked for over a year (2 MOTs!) for the first time since I've had a 205.

No, don’t use Copper Grease, it’s not a good conductor, Contralube is the best, although £25 a small tube but it does go a long way, use sparingly.

I’ve started using the Contralube too, although too early for me to say how it performs, but I reckon the tube will

last a long time, you only need a small amount.

Contralube is an insulator! It protects the electrical connection between the metal terminals but it isn't a conductor itself.

Thanks for that, I thought it was a gel to improve conductivity,  live and learn eh!
