We use bleach and water with a drop of regular dawn dish washing soap. We put 1 TBLS bleach in a 32 ounce spray bottle add one drop of dawn and fill it up with water. We liberally spray the udder, use a new paper towel for each teat (we buy these in bulk) and thoroughly wipe down. After milking we dip their teats with a good quality teat dip and send them on their way. We have been doing this for years with no mastitis or any ill effects to the milk. The baby wipes seem very convenient- but the price could start to add up depending on how many you are milking.
