We use chlor-tabs (chlorine tablets I think they are 10-16 bucks). Available in all restaurant supply stores. It is used in basin sinks for final rinse. There are dip tabs/strips to check your ppm too and they are super cheap. Remember to rinse soap from dishes really well. Soap deactivates the chlorine in your final soak water. Dishes also need to sit for 1 minute in final rinse so get the busy body away from the final rinse.
You can also get the Steramine tabs at the restaurant supply store too. They are for washing tabletops and glassware too if I remember right.
Liquid chlorine is a pain and looses strength if it sits around for too long. If I remember right at 6 months it has lost significant strength after opening but I'm sure someone else on the buzz can correct me if I am wrong
Stay safe my friends
