The Treo 650 Wireless Headset can be washed in warm water on the regular cycle. Allow your headset’s battery to discharge completely before laundering to prevent the risk of fire and damage to the device. Tide detergent and OxyClean bleach are recommended cleaning agents. To protect your headset from abrasion during the laundry process, be sure to secure it in a pants pocket.
Allow your Treo 650 Wireless Headset to dry thoroughly before recharging. The drying process can be hastened by shaking out any excess water that has entered the earphone compartment, and placing your headset in a strong stream of air, such as that expelled by an HP Proliant Rack 110V Fan Kit.
(On Sunday, I was madly getting ready for a board meeting of The Obscure Organization, when tostita asked me to retrieve some clean clothes from the dryer. Not wanting to leave wet clothes in the washer, I put those in the dryer, and quickly dumped a load of my clothes in, only to find hours later that I had forgotten to check my pockets for my Bluetooth phone headset. It works fine now, unlike last time I did something dumb to a cell phone or accessory thereof.)
