The contacts on the bottom of a cordless phone appear to be small, metal pieces that are used in connection with a housing unit to charge the battery.

Wireless cell phones use rechargeable batteries for power. These batteries are charged by placing the phone in the docking or charging station. Using contacts in the docking station and on the bottom of the phone, the rechargeable battery is able to charge. If the contacts become dirty, due to dust or oils in the hand, they should be cleaned. Cleaning the contacts maintains a clean connection between the battery and the charger.

Pour a small amount of rubbing alcohol into the rubbing alcohol cap.

Dip the tip of a cotton swab into the rubbing alcohol. You want the cotton swab to be slightly dampened, not dripping wet.

Rub the cotton swab on the battery contacts on both the bottom of the wireless phone and the charging or docking unit. If needed, dampen the opposite end of the cotton swab, or use a new cotton swab. Do not re-dampen a dirty cotton swab.
