Lots of ways work, here's what I do.
I have a blue plastic drum with a black lid, you know the type, add water and bleach but don't be mean then submerge your bottles and leave it for a few days. Lid off give it a sniff if there's plenty of chlorine give the bottles a shake and put them back upside down. You may need to add more bleach if the sniff doesn't leave you choking.
The trick is to forget "contact times", they are minimum times derived under perfect lab conditions, and give stuff a jolly good soak, it's OK take a week it's no effort. If you don't have time till next Wednesday great the bottles don't mind. If your only doing a few bottles use a smaller container whatever you have!

Bleech is great on glass but obviously need a good rinse
Re: Renovating Bottles and Demijohns
I have used cheap thick bleach for years. Works wonders diluted. Rinse well, of course!
