Contrary to popular belief very few citrus cleaners are successful as a mold remover. Most citrus type cleaners will mask the mildew/mold smell and maybe even temporarily remove the mold but over the long term.
This site was started to help others resolve an issue I experienced first hand, having mold in my house after some pipes in the basement burst sending water onto many of my belongings ruining them, but worse yet I was gone on a business trip for a month, guess what I returned to a real mess! Thankfully a friend checked on the house and turned off the water main, and all the water drained out but this didn't stop the mold.
