Star San question

recently noticed my container’s cap broke, and now the (concentrated) Star San is exposed to air. Will this render the Star San ineffective??

This always happens to mine, I guess over tightening. Never seen a problem.

Five Star will send you a new cap if you contact them. There were manufacturing problems with certain batches. I covered the bottle opening with duct tape and used the rim of the cap to finish the seal. Soda bottle caps will fit some of the Starsan concentrate bottles.


The cap from a soda bottle works as a great replacement.
