    Default Any expiry for cleaning solution ?

    I'm using the normal type of cleaning solution which comes with a cloth, big blower, tissue paper...etc, those no brand $8 to $10 cleaning kit. I notice there's no expiry date stated on the solution bottle. Is there any expiry for cleaning solution ?

    I'm just afraid if the solution has expiry and is expired, it might damaged the lens coating...

    I've also been wondering for a while.
    Someone told me before if kept for a year, try not to use it if you're afraid that it may damage any coating etc.

    the problem is that when i bought the cleaning kit, i do not know how long it has been at the shop before i bought it.

    Worst case is it won't just clean anymore because some ingredients have evaporated. Properly sealed bottles will keep all content and prevent impurities. When microwave ovens need warnings stickers about "Don't use to dry your pets!" then a cleaning solution for expensive lenses should not become corrosive without proper consumer warning, right?

    Thanks Octarine, I think you got a good point there...guess I will just go and look for a more reputable brand or possibly a sealed bottle solution this weekend, just to be safe.
