BH> Don't let the temperatures exceed about 150 deg. F. when BH> drying! Can be done in an oven with a cookie sheet between BH> the heat source and the drying item. Set thermostat at approx. BH> 125 deg. To remove residual moisture from enclosed items such BH> as keystems, etc., try immersing the "coffee'd" item in BH> ISOPROPYL ALCOHOL after the wash in distilled water to which BH> a SMALL AMOUNT of detergent has been added, about one table BH> spoon per gallon. The alcohol absorbs the water very readily. BH> FOR GOD's SAKE, DO NOT try to dry the item in the oven or use BH> a hair dryer after this treatment!!!!!!!!! BH> Just set it in the sun outdoors for 20 to 30 mins. in the sun. BH> My previous employer (a large computer mfgr.) BH> recommended this procedure to customers whose large CPU's BH> and I/O units had been exposed to fire fighter's efforts BH> (foam, dry chemical, etc. or other source of physical BH> contamination.
