Connie,
We tried this with a regular black light light bulb for a lamp and found maybe one or two very small areas that turned a very slight color. But then we borrowed our neighbors real strong blacklight....and oh boy....what we found was a HUGE mess.....and we had been using cleaners and steam cleaning the carpet all the time!! We ended up pulling up all the carpet in the living area and hall and installing laminate hardwood floors.
Maybe your blacklight is not very strong if you think there should be spots??
Just a thought....maybe you are lucky and everything came up!!! Good luck!!
