Just wondering how long the solution will last for and is there a recommended place to store it ie out of sunlight etc?

This is a bit like "how long is a piece of string" type question as every manufacturer utolises varying ingrediances and therefore they all have a different shelf life.

In general terms most liquids would last between 12/18 months un opend and 6/9 months once opend.

Of course how you store the liquid will also could have an adverse effect to this.

Again generally speaking best kept in a cool,dry place out of direct sunlight particularly once opend.

In hot summer months a good tip is to store your liquid in a fridge.

Hoping this helps

Thank you I just need to make room in thr fridge now!!
