Couple days ago I was cleaning up my garage and I over cross some detail formula (Zymol Detailer Spray, Zymol Cleaner Wax, Meguiar's Deep Crystal Paint cleaner) that were use about years ago. Now, I'm not sure whether I can still use it because I had last used Cleaner Wax and Detailer wax on my car in 2003, and the Paint Cleaner was last used by my brother on his race car in 2002. The formula are still smooth inside and it's not gunk up like a rock yet, so yea...

For cleaner Wax,is that the step before wax? I remember did after HD Clense.

 

All zymol liquids have a shelf life of 12-18 months. Outside of that, just chuck it and get a new one. Their waxes are good indefinitely if kept in the fridge.

Cleaner Wax is a polish/wax combo. You use it by itself. If you wax seperatly, then you hd-cleanse before applying the wax.

 

Considering the somewhat fragile nature of the diminishing abrasives found in most polishes, messing with shelf life really isn't a good idea. Not only are the polishes highly likely to react very differently than when they are fresh, there is a potential for them to actually cause harm to the paint finish.

Most polishes aren't all that expensive, so it isn't a big deal to replace them rather than trying to get as much blood as possible out of the stone.

 

Such waste, Looks like none of them can be use anymore.
