Dry it with kitchen towel paper first by pressing down hard. Then some baby wet wipes, press it down firm on the urine spot... then press it down hard to remove the wetness with a kitchen paper towel or dry cloth/towel. Can do it once/twice then let it air dry completely, usually in air con room it dry very fast, just dont lie down on that spot, if really need lie down can use baby rubber mat put over and just slp on it. If not sleeping, remove mattress cover also, it dries better.
