Stop. Bleach is a sanitizer, and I see no evidence from your post that you have CLEANED the bottles yet.....particularly given the source.
First, CLEAN. Lots of things you can use, including a bottle brush and good old dishwashing detergent.....and, of course, elbow grease. Or, you can use Oxi-Clean (or one of the many other brands for that formulation), and just soak them. Other products are B-Brite and One Step. My personal preference is PBW (Powdered Brewery Wash), made by Five Star Chemical. The latter products should be available from any homebrew supplier. Note that you must rinse any of these cleaners, and rinse well.
Second, SANITIZE. The main items here are bleach, iodophor, and (increasingly) another Five Star product called Star San. Bleach must be rinsed, while iodophor and Star San (when mixed according to manufacturers' recommendations) are no-rinse.
If bleach is what you've got, use it. Put 1T (one tablespoon) of bleach per gallon water, then, AFTER YOU MIX THE BLEACH AND WATER, add 1T white vinegar per gallon of sanitizing solution. Under no circumstances mix the acid (vinegar is acetic acid) directly to the bleach, or you will be able to have your own personal re-enactment of the Battle of Ypres in World War I. The vinegar will acidify the bleach/water solution, and it will function far, far better as a sanitizer. Regular grocery store bleach (Clorox, etc.) is only designed to function as a laundry whitener, not a sanitizer. For more on this, there's a podcast on BBR where the guy who runs Five Star Chemical talks about this. Personally, I quit using bleach a long time ago in favor of Star San.
Further note: The operation of some of these products depends on your water supply. do not attempt to use Star San with hard water, for example.
Once you're cleaned and sanitized, you're ready to fill those bottles with beer. There should be many, many other threads on this and other forums dealing with these issues in greater detail. Search is your friend.
