Expiration of Compounds, Polishes, etc

[prostar]

Hi all,

I recently came across a garage sale where I picked up a bicycle and happened to come across some detailing products. The guy threw them in when I bought the bike.

My question:

The seller says he hasn't used the products in over 1 year. These are mostly Meguiar's products. Do these products have an "expiration date"?

If a complete list of products is needed, I can provide that when I get home tonight. Your inputs are appreciated! Thanks!!

I have the definitive article and answer on this...

I created a forum group called, "Blast from the Past" , here's the article,


MGH-4 Hand Cleaner - Still Good After All These Years!



In a nutshell, and this goes for all liquid care care products, if you shake the product up well and then pour some out and visually inspect it, if the product has a,

• Uniform appearance
• Uniform consistency

Then it's probably fine to use. The enemies of longevity and product usability are extreme heat and freezing temperatures.

This would be a good idea because some old school products, while great products, are best used by Pros and need to be applied using a rotary buffer only.

Too many people don't read "all" the instructions on the back of the label and then don't do a "Test Spot" and find themselves in a world of hurt....

Great! Thanks for the help Mike. I'll post the list of products tonight.

I have some products on my shelves that are older then some of the members here rops:

I've been wondering about this too since getting a few 32oz Menzerna products. I'd probably never actually finish any of these with just two cars to care for (you can only polish one so many times after all) and perhaps the occasional friend. But Menz was nice enough to put a sort of expiration date on their bottles. It says: 24 months @ 59 to 77 degrees F. At $30+ per bottle that's a bummer.

So would the same rule of thumb apply to these too? Like maybe Menzerna is just trying to increase sales this way?

Someone once said shaking the bottle occasionally to keep it from separating too much was a good idea. But I don't know about that.

If you can keep your product at around 60-65 degrees, I don't see why it wouldn't last 5+ years. They may write 24 months on the bottle to protect themselves, in case someone improperly stored the product. It's simply a release of liability.

I learned from BigAl, just shake your products (that require shaking) once a month, and you'll be fine. I shake mine every 5th of the month. I also keep most of my arsenal in one of my bedrooms, for constant cooling.

There's your million dollar invention idea! You know how they have the boxes that rotate watches? You just need to invent a box that rotates your Detailing Stash!

:laughing:

Oh ok, great. I don't do it once a month, but a few times a year I have been giving them a good shaking. The problem is when they're full/new there's not much room inside to get much action. Perhaps taking some out first is a good idea.
