I used a spray bottle with Star San last week and did not use all of it. It's still sitting in the bottle...diluted. Will it still be effective this week from that spray bottle or do I need to dump and dilute a fresh bottle full with hot water / stasan for my brew this weekdend?

thx

I think it will be fine. I that all the time. If you're concerned you can check the ph. I believe their website lists the effective ph range.

A general rule is if it is still clear, it is good. Cloudy is bad. Stability will depend on the makeup water. If your tap water is alkaline, the solution will go bad faster. I make my dilutions with distilled water and use it for a month or more.

Did you use distilled/RO water in the bottle. If so, and since it is sealed you are good for weeks if not months.

Then keep an eye out for cloudiness...you'll only gonna get a few days til it's useless. Best to use RO/Distilled water. No minerals for it to react to.

Using tap water, mine was cloudy as soon as it was mixed.

it can still be effective if cloudy which is why they suggest checking ph to be sure

The price of pH strips is as much as 100's of litres of star-san. I will just make a fresh batch when it goes cloudy.
