Place a chunk of bleached beeswax the size of a quarter on a plate. Heat in microwave until partially melted (some liquid and some soft wax). Remove and add 2 - 3 drops of lavender oil and mix into a creamy goo. Make a 2 small buffing pads out of a well-washed flannel shirt. Dip one pad into the waxy creme and apply to your print in a circular motion. Allow to set for a minute, then use the other pad to buff it out in a straight line motion. Never did this in plats. but it makes my salt prints DMax much deeper.
