Lets look back over time, 50, 75 or more years.
Apparently detergent strength soaps were commomplace.
Waxes were advertized as "serving the automotive, institutional and industrial marketplaces".
Institutional and Industrial (and Marine) marketplace I think is the origin of detergent proof durability.
Industrial strength wax to resist industrial strength soap.
The auto...anybodys guess on what soap someone would use in those early, mid-century days on their car.
During those radio broadcast years a leading company in the field had a popular slogan "Motorists Wise, Simoniz".
Collinite founded in 1936 was in the period of such strong cleaning products and had products to do just that.
Apparently chose to rely on word of mouth promotion (popular in the yacht yards, marinas, etc...)
Fast forward to today, with all options to pick from around the home, a detergent product, such as laundry
or dishwasher detergent would seem excessive just to wash the car.
But many would consider a Dish Soap and have over the past maybe 50 years.
So, Collinite degrading...why not? Isn't that part of the theory behind using any wax?
Impart a shine, protect and in the natural flaking / degrading process take along embedded surface grime.
And in time completely remove it with solvent or a companies cleaner wax product.
Your choice...to degrade (waxes) or not to degrade (coatings).
