Does neem oil solution store?

Does anyone know if a mixed solution of neem oil i.e oil, water and soap will keep for a short time?
In the past I've just mixed enough to use in one application, but it's a real faff to mix and it occured to me that I could maybe mix a larger quantity and use it as required.

Thought I'd escaped red spider mites on the cucs this year, but the little beggars are out and about!

 

Hi dave,i used to mix a wilkies spray gun up( half litre?) and use it over 3 evenings for the horses and it seemed ok,id just give it a good shake.
I only use small doses now for some plants but still put 5ml of neem oil in

 

I have read not ... but maybe they just want to sell me more?! Tends to gum things up if left in the sprayer though

 

Your're right Kristen it's horrible sticky stuff. I'm not keeping it in the sprayer but in a 1 gallon container. I always rinse out the sprayer after use.
