Jan Rowland It warms up a little when you add the peroxide, so let's say it is used at around 20F above "room temp". You really want to make and use this stuff outside because of the HCl fumes (which actually *diminish* after mixing with the peroxide), so heating it up in the microwave or on the stove would probably be a "recipe" for a kitchen disaster... pardon the bad pun. -Jeff
