Does steriliser go out of date?

[GhostShip]

Someone who used to home brew chucked some stuff my way. It gives me an extra barrel and FV, along with a hydrometer and syphon.

There was also a 6 year old Coopers Ginger Beer kit and some brewing sugar, which I’ve dumped.

There is an unopened pot of Young’s steriliser/cleaner (powder that you add to water). It will again be around 6 years old, but does steriliser have a sell by, or is it just not worth the risk?

Its a sealed package of dried chemicals. Its very unlikely to go out of date.

Checked my Youngs steriliser powder & it doesn't have a use by date or a once opened used within x months - so I'm pretty sure it should be OK.

Don't sniff the powder directly - its dangerous, but if you mix a bit up with water it should feel slightly soapy & smell of chlorine
