Subject: What product will make foods decay faster?

I am doing a science project for my chemistry class where I put different
household products on items (I have used apples and bread so far) to see if
any of them will make the foods decay faster. I have used products such as
bleach, glass cleaner, peroxide, alcohol, and nail polish remover. Is there
anything I should know, such as chemical makeup or reactions, that would
cause them to make the foods last longer or cut short the lifespan? What
effects will these chemicals have on these food items? Any information I
could get regarding decay and molding or any sites that could help me with 
my project are greatly appreciated. 
  Thank you, LP
