I use the bleach / water solution also. Everything you read will tell you not to use the bleach, but q-tips are also not to be used for cleaning your ears (go figure). I also use the same solution to clean the vinyl siding on my house - nothing beats it!
My wife's grand-father has been camping for 40+ years, and has always used the bleach / water solution. In reading your original post, I was imagining him as being the one who told you about it to begin with. Sounds like him!!
