metabisulphite in spray bottles

[wobbly_bob]

Hi

I have seen on a few youtube videos of people making up sodium metabisulphite into spray bottles and storing it to use for quick sanitation. I always thought that the metabisulphites break down pretty quickly and could actually harbour bacteria if allowed to pool for a period of time.

Anyone have any ideas on how long sodium/potassium met can be left in a spray bottle and still be effective?

thanks

Good for neutralising chlorine, not good for sanitising.

Try iodophor or star-san for instant no-rinse sanitising.

Doesn't half get on your Lungs used in a spray bottle!!! But handy as stated above

I use this stuff in a washing up liquid bottle and use boiling water with my bins and FV's after using VWP, never had any problem with infection.

Its the VWP that does the killing, the sodium met solution just neutralises any chlorine residue and prevents bacterial growth, it isn't an effective sanitiser on its own though.

Of course, I wouldn't use it on it's own, although it does I find the two make very good partners though. Sodium met is also very good as an anti oxidant, I always leave the dregs behind before I fill up my FV.
