i wash with liquid tide (do not over-use liquid detergents as they are very concentrated these days), and add about 4-5 oz's of vinegar on the last rinse cycle (if you notice there is alot of soapy water still, do another rinse cycle). then off into the dryer (i like to shake each mf out before putting them into the dryer as they are bunched up from the washer) on the lowest heat setting with no fabric softener or dryer sheet...
