last year i started using scent killer autumn laundry detergent, and spray, and fresh earth cover discs. i didn't really notice any significant advantage from using them, but i would think that the non uv brightner detergent has to help. besides, that stuff does smell like my woods, so iti don't think it's going to hurt anything. i haven't gone so far as the soap, deodorant, and shampoo though. that's where i begin to question how much the stuff works and is it worth it.
