It is good to have if you are a retro game lover since a lot of retro games comes with this type of screws. 4.5mm bit screws are used on consoles.

You can buy Brass metal brush at your local hardware store or online shop like Amazon.  I found it at Lowes for $4~5 a piece.  Sorry mine is heavily used and doesn’t look pretty.  There is a stainless steel brush also but I use brass one since brass is softer than stainless steel.

Next, unscrew screws from cartridge.  Make sure you unscrew counterclockwise.  Those screws are very old and can be very fragile.

You don’t want to strip the head of screws.  It is extremely hard to remove a screw with stripped head.

Now, remove front part of cartridge.

First, soak Q-tips into rubbing alcohol.  Then, wipe connection with wet Q-tip.

The key here is make dirty part wet to soften it.

Caution: Before you touch the circuit board, make sure you release static electricity from your body. You can do it simply by touching the ground. You may be able to use rubber gloves if you want to be very safe side.  Also, try not to touch or brush any parts on circuit board while brushing.

After you brush it, use wet Q-Tip and scrub the connection again.

You can already see Q-tips is getting dirty. It is good sign!

Now, use paper towel or cloth and wipe wet areas.  Make sure the connection is completely dry before you go to next step.
