unless you go for one of the contact cleaers that contain acid...hmmm....none of them will touch heavy corrosion or even heavy tarnish.
the use of a "contact cleaner and lubricant", along with or after some sort of mechanical cleaning may improve the cleaning effectivness and reduce the speed of corrosion after.......the word lubricant is critical for the long term.
I have used many contact cleaning products in my career ranging from contact burnishers and microscrub ( a 3 m product) thru to files and grinders.
for fairly soft contacts bassed on copper and plated with nickle, tin or whatever...I have found scotchbrite pads to work quite
well.
There are dedicated similar purpose made scotchbrite and similar products intended for the purpose......but for most medium to large contacts schotchbrite can be made to work.
Just be carefull because it can scrub all the plating off the contact.....if the contact is badly corroded....bare copper is better than corroded plating.
another thing that can be handy is those little brass and stanless brushes.
for the insides of round contacts..arrond the 2 to 3 mm in diameter....about all mere mortals can get hold of is pipe cleaners.
Pipe cleaners come in standard and prickly...the standard ones are best for actual cleaning and the prickley ones better for scrubbing.
use them with contact cleaner.
I have recently baught a fiberglass contact cleaning stick...I have not used it yet, but I know those who swear by them.
They are a retractable pen type stick and you just scrubb at the contact with
the tip.
Of couirse there is the old favorite...hose as much carp out of the contacts with the contact cleaner...then while there is still plenty in there and the cntacts are still wet...plug and unplug vigorously several times......dont forget to hose out with more cleaner after.
hope this helps.
