MGH-4 Hand Cleaner - Still Good After All These Years!
Over the weekend I used a bottle of MGH-4 Hand Cleaner that is Post WWII and probably from between 1950 and 1960 to remove stains from antique lacquer paint on a 1938 Packard Model 1603
Lots of people will join our forum and ask the question,
What's the shelf life of Meguiar's products?
The official answer is 3-5 years as long as the product hasn't frozen. That said, if the product has never frozen it's possible you can shake it up and if it still has a uniform appearance and consistency it's probably perfectly fine to use. Such is the case for this old glass bottle of MGH-4
Here a few pics...
A protective plastic wrap was placed on the paint to protect it while the car was transported from the East Coast to Palm Springs, California. After the plastic wrap was removed it was discovered that the paint had been mottled or stained after moisture got underneath the plastic.
