Hi all, I'm looking for some assistance please, I've had a problem with the passenger side rear light on the body where the lights were dim. I removed the unit this evening and gave the contacts a quick blow, and it seems a bit brighter. But still not as bright as the drivers side.
Whats the best to clean the contacts with?

i was using this post for some of the details, but don't want to resurrect an old post.
