Most game disc manufacturers do not recommend using anything but water, but that's not always going to get the job done. These alternatives below are listed with the safest methods at the top, increasing in risk as you move down the list. Always use gently motions when cleaning to reduce the chance of scratches. If you aren't prepared to risk damage, search online for a mail-in disc repair service in your country. These services may have buffing machines or cleaning products that are not commercially available. This method will not repair scratches, but should remove grease stains. Apply a dab of isopropyl alcohol to a clean cloth, and rub the disc from the center to the rim. Carefully wipe off moisture with a dry cloth with the same motions, then let sit for two minutes so it is completely dry. Since dry cloths can cause scratches, some disc owners prefer to let the disc air-dry for half an hour or more instead. If the game still won't boot up, purchase a "disc repair" product in spray bottle form and follow the instructions on the packaging to clean the disc. This may be sold as a "CD/DVD repair" or "scratch repair" product. Using a disc repair buffing wheel or other machine that comes with the disc repair product is highly discouraged, as these can cause damage. Always check the warnings to make sure the product is safe for your type of disc. Toothpaste is slightly abrasive, and can polish off scratches with low risk of causing more damage. For maximum safety, avoid whitening and tartar control toothpastes, which tend to be more abrasive. Apply the toothpaste as you would water or rubbing alcohol, as described above. The toothpaste must be in paste form. Don't use a gel, liquid or powder. If toothpaste doesn't work, you can move on to plastic polish, furniture polish, or metal polish. These are also slightly abrasive, but because they are not intended for game discs, there is a higher risk of damage. Always check the ingredients list for "solvents," "petroleum," or petroleum based products before using, as these can dissolve through the CD and destroy it. If it smells like kerosene or gasoline, don't use it. Some people report that Brasso metal polish is effective, but this does contain a mild solvent. Use at your own risk. Deep scratches can be filled in by gently applying a clear wax, then buffing it in with a clean, dry cloth moving in straight lines from the center outward. 100% carnauba wax or another non-petroleum-based, clear product is recommended.

summary: Understand the risk. Mail your disc to a repair service. Remove fingerprints and grease with rubbing alcohol. Purchase a disc cleaner spray. Use a non-whitening, non-tartar-control toothpaste. Select a safe polish. Use a clear wax.

Summarize the following:
Speak warmly and engage those whom you are speaking to. Be able to speak comfortably about a wide range of topics. Avoid vulgar and poor language, as well as using words like "um" or "like" to punctuate your sentences. Communication isn't just talking it's about listening, as well. Incessant talking isn't the mark of a respected person. Try to truly listen to others and be genuinely engaged so you become more trustworthy. Take a moment to think before you speak. Remain calm in tense situations and speak in a calm, relaxed voice. Strive to act, rather than react emotionally. Diffuse bad situations whenever possible, and take a moment to think before instantly reacting to a negative provocation. Well-respected people know how to keep their cool under tense conditions. During arguments, hold your temper to prevent escalations, and if someone raises their voice at you, respond calmly. Stand up straight, look people directly in the eye, and speak in a steady, composed voice when in conversation. These things exude confidence, which people very much respect. Conversely, slouching, mumbling and being afraid of eye contact communicates to others that you aren't confident in yourself. Self-confidence is respected. When faced with a problem, do not react emotionally or with visible frustration. Instead, focus on addressing the problem and looking for ways to solve it. Try not to complain or get angry, since neither of those things are going to help the situation. When others see you calmly find a solution to a problem rather than react angrily or emotionally, they will respect your composure and appreciate your readiness to remedy the situation. Always practice good hygiene and make sure your clothes are neat and clean. Take the time to be well-groomed. Keep your nails trimmed, shower daily and always brush and floss your teeth. Being poorly groomed usually sends a negative message to others about your self-worth. If you don't respect yourself and your appearance, it will be very difficult to gain the respect of others.
summary: Excel at communication. Keep your emotions in check. Control your body language. Solve problems. Take pride in your appearance.
