When we found the stains it will only show up stains that have a ph.. like pee, salvia, germs etc. We thought some of the stains could be from my almost 2 yr old sippy cup... (wrong)... We tested this by putting milk, juice, and soda on the floor let dry and tested... Guess what... it did not show up under the black light.
Therefore according to a chemist at hubbys work only something that has ph or grease will show up?????
This lead me to believe that most of the stains I saw were pee stains... cause I sure hope no one is spitting on my carpet.. lol |
