85 year old man could not make it to the bathroom in time. Wet his pants and drip on carpet next to bathroom. Many bright yellow spots. Cleaned it and dried the area then sprayed stain magic and covered it. Came back an hour later and it did not change. Sprayed more on it and tried to steam a little area at 10 seconds intervals did not vas it. Does any body have any suggestions? PS The man was on medication at the time this might have a lot to do with it. THANKS.....................
