Is it safe to put bleach in a toilet that already has drop ins in the tank?
by safe do you mean there wont be an explosion? (youre not drinking the water right?)and isnt there bleach already in some drop ins? i think it should be ok. it may just not give you the blue color anymore. are you putting it in the tank or just the bowl? extra clean freak huh? =)
I was always taught to never mix bleach with anything that has ammonia in it - something about it turning into chlorine-gas and killing everyone in the neighborhood.. although my mother probably exaggerated a bit, you probably get the idea.
Read the label to make sure your DropIns dont have any ammonia - if they dont it's probably safe, unless there is some other danger i'm not aware of.
If in doubt, consult with a chemist.. or meth-cook.
I recently asked my plumber about using those drop-ins, and he suggested not using them. The reason I asked, is that I noticed a lot of residue at the bottom of the tank from them not fully dissolving over time. It was gunking stuff up a bit. He said a better idea is to buy the large chlorine tablets they sell at Pool supply stores - put it in a ziplock and smash it into some pieces, and just put one piece of it in the toilet. Alot cheaper than to keep buying dropins too.
