Rinse and Dry
Immediately after removing the paper, place it in a pan, and pour water over it. Hang paper to dry, marbleized side up. Do not touch the paper until it is dry (typically within 2 hours, depending on humidity levels).
Decide whether to keep or discard your solution (it can be used several times). To change paint colors, lay strips of newsprint across the solution's surface, then remove; repeat with clean strips until the solution is clear. You can store the solution in an airtight jar for about a week. Don't leave it in the tray, which could rust. If you have excess solution, do not pour it down the sink -- it may clog your drain. Instead, pour the liquid into a resealable bag or plastic container, and throw it away. (There are no dangerous toxins to be concerned about.)
