Optimum polish previously frozen.. still good?

[blackout-spec]

So i am a long time lurker on these forums, i pretty much never post because i always find my answer when searching... Anyways i finally have a question that i didnt get a definite answer to when i searched.

I purchased some Optimum car products 2 years ago from this site. I bought some polish, compound, and a all in one bottle ( all 1L bottles ). Anyways, since i dont use them very often they tend to separate, kind of like a salad dressing.

I am wondering if they are still good to use on my car? I shake them and they always mix back together but will they still perform and work as they did before? or will it be like trying to polish my car with plain tap water?

I am not 100% sure if they froze because my garage is insulated and barely gets below zero, but i am 100% sure they have separated.

Thanks in advance!

Remembering what the product looked like when you got it would be a start. If it looks entirely different; runny, clumpy, or very thick then I'd say they're probably dead.

If when you shake them they mix well give them a try and see how they perform. Try a small spot by hand and if the results look promising then proceed!

Well it mixes back together properly, so i figured it was fine. I was just worried mostly if the chemicals didnt mix properly they could damage the paint.

Thanks for the reply!
