There are instructions on every bottle but in general they are shake well. Always apply to the "side without printing", use a soft cloth, cotton or swab. Make sure the CD is clean and dry before playing. One thing we would like to highlight is that each product is white or milky...so you can see where it is being applied.
Repair Directions
Only use on side without printing. We recommend to always trying GP first because, by itself, it takes care of 70-80% of repairs. Shake the bottle well. With a soft cloth, cotton ball or swab, apply just enough to cover the surface. As our bottle directions state, you want to rub firmly. How long depends on the type of damage. Your goal is to "reduce" the depth or sharp edges. After you have rubbed, let the CD sit for about 5 minutes and then clean, preferably with CD Doctor Cleaner (of course). It's easier to remove residue when it's wet or slightly dull and it's best not to let dry completely. If, when you play the CD, it still skips, you should keep trying, repeating the application and rubbing process, but also trying to pin down the actual problem scratch and concentrating effort to it. Often you will notice sections of the former skip are ok, but there is still a little skipping. This tells you your making progress. Again, be sure to clean off any residue before you try playing the CD. If you've tried the GP 2-4 times and there is no noticeable change its time to move to Acute Real Bad Problem Repair.
Now is the time to mix a small amount of Acute with GP to form a paste. In this treatment you will want to do your best to locate the specific area of damage. You do not want to use Acute on the entire surface. Depending on the shape of the scratch you will rub it with paste in either a circular or back and forth motion. In most cases, you are trying to reduce the depth to a point that GP's coating ability will work. This may take some trial, but is successful 95% of the time and it shouldn't take too long to complete the job. The minutes involved save you money when the price of a new CD is compared. After an Acute treatment, apply GP as directed previously.
This is "not" something that we suggest to be used very often but...for the brave or impatient...you can take out the initial deep scratch or gouges with a high grade 800 to 1000 wet/dry sandpaper. This will cause fine scratches it's self but they can be removed with Acute followed by GP.
Sometimes you may think that a big scratch is the problem and it's not. We don't know why but it does sometimes happen that hairline scratches cause more skipping. This could be because it is more abrasive on the edges and is causing deflection while the large scratch is more like a scuff with round edges.
All CD Doctor products are safe when used as directed. GP and Acute can be drying to your skin left on too long. If you happen to get any product in your eyes flush the well with water to remove possible abrasives. Do not swallow any products and keep out of reach of children.
