So, you let your buddy borrow your copy of Hitch and now it’s scratched because they didn’t show Will Smith’s romantic comedy the respect it deserves. Sure, you could go out and buy another copy, but who knows how hard it will be to track down — especially that special edition double feature that comes packaged with Bewitched. Thankfully, there are a couple of methods for saving your discs that you should give a shot before you disown the irresponsible guy you once called your friend.
Before we go on, though, it should be noted that the best way to deal with a scratched disc is to simply replace it either through the store where you bought it or by getting in touch with the manufacturer. In the case of video games, many publishers will send you a new copy of their title in exchange for the damaged copy and a nominal fee. You should also keep in mind that all of the methods below have the very distinct possibility of further damaging your discs, even when done carefully using our guidelines.
It’s also important to note that these methods will not work with Blu Ray discs given the discs use a harder coating that is more difficult to scratch and damage. The downside to this is that once it does scratch, the disc typically becomes unusable and has to be replaced. Minor damage may be corrected with a micro-fiber cloth, but the data density and layers prevent any of the options below from working particularly well, or even being advisable.
There are all sorts of ways you can damage a disc, but it’s important to identify how deep a scratch is or what caused the disc to malfunction before proceeding. The first trick is to identify that the problem is actually the disc, usually done by trying to play it in another device with a disc drive or inserting another disc into the original drive that gave you issues.
Five tips before moving forward
While we cover the different methods for cleaning and resurfacing your discs, it’s important to remember a few key rules should you want to save yourself a headache while going through the process:
- #1: Wash and dry your hands before you start or handle discs at all. It’s surprisingly easy to mess with the delicate data shaped onto a disc’s polycarbonate layer, and moreover, grease and oil can both cause playback issues even if the disc showcases no signs of physical damage. Better still, snatch a pair of latex gloves, if you happen to keep them around.
- #2: Always rub outward in a straight line. The best (only) way to clean your discs, with any material, is to start at the center of the disc and work your way outward in a straight line. This way you can not only hold the disc better while you’re cleaning and rubbing, but you’ll also avoid damaging any of the data printed onto the polycarbonate layer below. The reason for this is that the data runs in a spiral around the disc, in much the same way as a vinyl record. Because the disc spins so fast, the reader has to be able to compensate for missing bits of the data as it goes, and when a scratch runs straight out from the center of the disc to the edge, it’s a lot easier for the algorithm to catch the error and fix it.
- #3: Tray-loading drives may be more likely to read a damaged or scratched disc than slot-loading drives. It’s a good idea to use one of these drives when trying to salvage a disc to lower the number of variables at play.
- #4: Given the layer of data that’s encoded onto the polycarbonate surface is so close to the top layer of the disc, scratches and dents on the label can cause read errors in the same way a ding in the reflective surface can. Make sure to store all your discs in cases or on spools, and handle them by the inner ring to avoid damaging the data.
- #5: The best way to repair discs is not to scratch them in the first place. It sounds silly, but using good cases and spools significantly reduces the chance of damaging a game or DVD — saving you the hassle of repairs in the first place.
Method #1: Mr. Clean Magic Eraser
Mr. Clean’s budget-based pad may commonly be used for household cleaning, but it’s also surprisingly useful when it comes to restoring the proper finish to optical discs. Although you typically wet the magic eraser, lightly rubbing a dry eraser over the reflective surface of the disc — again, always in straight lines from the center of the disc outward — may smooth out some of the scratches on the reflective surface without affecting the data underneath. The Mr. Clean Magic Eraser is made from melamine foam, the same kind of foam used for sound and heat insulation, and takes advantage of the unique properties of the material rather than chemicals to clean surfaces. The idea is that the foam acts as an abrasive, like sandpaper, and may smooth out the outer layer of a disc and result in a smooth surface to read from. Think of it like pumice stone on your skin; you’ll get some of the dead skin off, but if you rub too hard you’ll take off the important bits underneath. You have to be really careful to not rub too vigorously on the disc, or you’ll risk damaging the data layer underneath.
Method #2: Expensive Machines
Unless you want to spend $500 or more on a professional resurfacing machine, it’s best just to avoid this option altogether. While these high-end devices are great for people who need to clean and fix hundreds of discs a month, they’re prohibitively expensive to buy, and often require an upkeep cost that quickly exceeds the cost of simply replacing a few scratched DVDs. The less expensive versions, which you may see on clearance shelves for $10 or $20, tend to do more harm than good, often scratching recoverable discs beyond repair or simply dousing them in chemicals that only further damage their exterior. However, it’s common to find these machines at video game or movie rental stores that sell used discs — yes, they still do exist — and they’ll often let you use theirs for a nominal fee.
Method #3: Wax
This is where things start to get a little messy. If you’ve reached this point in the guide, hopefully that means that no other method has worked. If you can get a single computer to read a copy of the disc, you can burn a replacement copy on a new disc so that you don’t have to worry about the scratches on the old disc. If the scratching is too severe on the data side of the disc, it may have permanently damaged the outer reflective layer. In this case, you may be able to get one more use out of the disc by replacing the material with something comparable in order to read the working portion of the disc again.
You can use a number of different materials at this point, some effective, and some born from rumors and common misconceptions. Chapstick, toothpaste, peanut butter, shoe polish, window cleaner, petroleum jelly, banana peels, and a number of other materials are purported to work for repairing a scratched disc, but they all have one commonality: oil. The oils in these substances will help fill in some of the gaps left from scratching, even after they’ve been wiped clean.
Method #4: Heat
Again, if you really care about your disc and want to save it, you’ve probably already taken it to a professional by this point. Nonetheless, if you’re still committed to watching your scratched version of Hitch and watching it tonight, then you could try slightly heating the disc. Polycarbonate has a very low melting point, and becomes very malleable with only a bit of warmth. A desk lamp will do just fine, and you can just hold the disc through the ring in the middle up to the bulb. You don’t need to bend it at all, or flatten it, we’re just hoping that a little bit of heat will correct any minor scratches in the imprinted data and make the disc easier to read.
So, none of the above methods worked and now you’ve got a disc that’s been scrubbed, salved, and still won’t play. You aren’t out of options quite yet, as there are still a number of uses for your non-functioning disc. For instance, you could put it on your coffee table and use it as a post-modern coaster or wear it around your neck as an ode to Flavor Flav. You could even collect a bunch an make an art project out of them. You get the point.
