or How I Learned To Love Used Games

DISCLAIMER: The author takes no responsibility for damage incurred as a result of employing any of the cleaning methods listed below. These are general recommendations based on his own personal experiences.
There was a time when I bought all of my systems and games brand new. When you start collecting classic games however, this is no longer practical. The idea of owning used games was not something I immediately embraced, being somewhat of a germ-o-phobe.
In time however I came to realize that it's quite possible to transform a dirty, grimy cartridge (or system) into something that looks almost new. I just takes some time, patience, and a little elbow grease. This article provides suggestions on how to clean used cartridges and other game-related items.
Cleaning Materials
A few inexpensive household items are all you need:
- Bottle of rubbing alcohol You can pick up a bottle for about a dollar, and it's really your main weapon for fighting dirt and germs. Water is NOT a valid substitute! Do NOT use it! Alcohol not only kills germs but evaporates quickly. This is crucial because water can seep into labels and corrode cartridge contacts. I have always used 70% isopropyl, but I hear it is also available in 93%, which is probably even better.
- Cotton swabs In order to access cartridge contacts (pins) and hard-to-reach nooks and crannies you'll need a healthy supply of Q-tips (any brand of cotton swabs will do).
- Lint-free rag Do NOT use a cloth that will shed tiny pieces of fabric that can get caught up in your cartridge. I personally prefer to use rags cut out of old bed sheets.
- Goo Gone This item is necessary if you have stickers or residue you want to remove from your cartridge or packaging.
- Disc Doctor This is only necessary if you need to repair a scratched-up disc.
Removing Stickers
Sometimes old stickers can be interesting for historical purposes, like when an Atari 2600 box has an old Kmart price sticker for $6.84. It's like going back in time! But for the most part I try to remove unsightly stickers, especially from cartridges.
f you're dealing with a plastic case (Genesis, Saturn, CD/DVD cases), getting rid of the stickers is not a big deal. If the sticker doesn't peel off cleanly or leaves residue, soak the area with Goo Gone, wait a minute, and rub it off with a rag. Repeat as necessary. In the case of hard-to-remove stickers you may need to use a smooth edge to gradually pry up the corners.
Please note that before applying any liquid to plastic cases, it's a good idea to remove any paper inserts or instruction booklets just in case any liquid seeps through.
What about stickers on cardboard packaging like SNES or N64 boxes? Applying any liquids to cardboard is always a risky proposition. If the sticker doesn't look so bad you might as well just leave it in place. Otherwise try to remove it slowly by pulling up a corner. If it tears, there's not much you can do. If there's just some sticky residue left you can usually remove it by wiping the area with a rag lightly dampened with Goo Gone.
Be gentle, and if you notice any discoloration (to the rag or box), you'll probably want to abort mission. Fortunately SNES boxes tend to have a glossy coating so I've had pretty good luck cleaning those.
Cleaning the cartridge shell
Rubbing alcohol is your friend, but before you get the cartridge wet, examine the label. Some of the cheaper labels are made of porus paper and you should avoid getting those wet at all. 20th Century Fox games for the Atari 2600 are one example. In rare cases (like Atari 2600 Pengo) the labels can actually be wiped away if you're not careful. Use caution and if unsure, try using an alcohol-dipped swab in a small, inconspicuous area.Fortunately 99% of labels (NES, SNES) have some kind of plastic coating so you can wipe them down easily. Sometimes alcohol will appear to discolor a label around the edges, but this goes away once it's dry. Always exercise caution however, and if there's no visible dirt you may want to leave the label alone.
Wipe down the remaining exposed plastic parts of the cartridge with an alcohol-soaked rag. Use cotton-swabs to clean all the nooks and crannies. Keep scrubbing until dirt is no longer coming off onto the rag. Except for minor scratches and tears, you can usually get a cartridge looking good as new.
IMPORTANT NOTE: Many old cartridges exhibit a condition called "actiplaque". This occurs over the years when glue seeps through the label, causing "speckles" to appear on the surface. This is normal, especially for Activision cartridges. There is really no way to remove these as they are soaked through the label, so don't press the issue.
Cleaning the pins of a cartridge
So this is where the rubber meets the road. It's nice to have a cartridge look clean on the outside, but the inside is even more important. In some cases dirty cartridges will not function and present a blank screen. Worse yet, plugging one into your NES (or other cartridge-based system) can harm the system itself. The dirty contacts can contaminate the console's internal pins, making it less reliable and prone to malfunction. It's much easier to keep a cartridge clean that it is a console, so never stick a strange cartridge into your system unless you know it's clean. This applies to other aspects of your life as well.
With most cartridges the metal pin contacts are enclosed in the bottom edge. The more exposed they are, the more they are susceptible to dirt, but also the easier they are to clean. Atari 2600 cartridges can be tricky because many have a protective lid covering the pins. To move this out of the way, insert a small flathead screwdriver into one of the rectangular holes on the bottom, and finagle it a bit to slide the cover inwards and expose the contacts.
Dip a cotton swab in the rubbing alcohol and run it vigorously across the contacts (both sides). Take a look at the swab and you'll notice it's discolored (usually gray but sometimes black). Pretty gross huh? Repeat with a fresh swab. I like to pour a little alcohol in the bottle lid, and use that to dip the swabs into. Continue cleaning until you can't see any more dirt off (the swab remains white).
It's possible to go through a dozen or more swabs if the cartridge is filthy enough. Once the pins are clean, run some swabs around the exposed plastic area. I have never felt the need to actually crack open a cartridge to clean the interior, as that would probably cause more harm than good.
IMPORTANT: Let the cleaned cartridge sit out a good half hour before sticking it back into your console. You can harm your console by sticking a wet cartridge in there, so err on the side of caution and don't rush!
If the cartridge still doesn't work, repeat the cleaning process. Even if you don't see dirt on the swab, it only takes one tiny particle to cause a bad connection. I would repeat the process 3 or 4 times before falling back on your last resort: sandpaper.
Take a small piece of sandpaper, fold into a small rectangle, and run it across the contacts a few times. If there's any remaining dirt, this should knock it loose. Just don't overdo it or you'll damage the pins. After sandpapering, be sure to repeat the alcohol cleaning method, as the paper will leave some grit behind
Despite the conventional wisdom, blowing into an NES cartridge is not recommended as it can have long-term consequences for your games and system. Saliva particles can blow into the cartridge and contaminate the contacts. You don't want that.
While these tips apply mainly to used games, I've also discovered that even new cartridges can become dirty if they're been on a shelf long enough. Even if you buy an unopened classic game, I'd advise you to clean its contacts anyway.
Cleaning CDs and DVDs
When I get a used CD or DVD, I look closely at its playing surface. If it looks clean, I generally don't mess with it. You don't want to ruin a perfectly-good disc.
Contrary to popular belief, CDs and DVDs are pretty durable. Most play perfectly fine even with light scratches, and few are ever beyond repair. There are several commercial products that "repair" scratched discs. I have an old one called the Disk Doctor, and yes, this thing really does work. By mounting a disk and turning a crank on this little device, you can effective polish away the scratches. I have enjoyed a high success rate, but I'm sure some deep scratches and cracks are probably beyond repair. NOTE: Polishing a disc will result in a distinctive, permanent pattern on the underside of the disc.

Cases and Boxes
Like cartridges, used game cases can get pretty filthy and can be treated just like cartridges. Once you've removed any stickers, use alcohol and rag to clean plastic cases. Be sure to remove any paper inserts (Genesis games for example) in case alcohol seeps under the plastic cover. Use cotton swabs to clean the edges you can't reach with a rag. Personally I never bother cleaning the case interior, but that's up to you.
If a case is badly damaged or scratched up, it's often easier to just replace it with a new one. I keep a supply of empty jewel (CD) cases for this very purpose. Often if you remove the manual, insert, and disc, and insert them into a fresh case, it looks like a brand new game. Replacement cases are available for just about any type of case, and they tend to be inexpensive, especially in bulk.
