Have You Been Fooled?

Almost everyone has heard of or performed the dry down test. You know, the one where the manufacturer tells you to pour some undiluted chemical into a concaved glass full-strength. This test is shear brilliance from a marketing point of view. It shows off a particular feature of their product. How it won’t leave a sticky residue that promotes rapid resoiling. However, there are many problems with this test in its current protocol.

First, you never use your chemical full-strength, do you? You never leave a coating of chemical on the carpet fiber an 1/8” to a 1/4” thick like in the bottom of a glass. This is hundreds to thousands of times thicker than what would remain on a carpet fiber after cleaning. Here’s an exaggerated example, but I think you will get my point. Go outside and stand up a broom or shovel against the wall. Now take your garden hose, pressure washer, fire truck or whatever you want that sprays and spray the handle of the broom or shovel. You can spray a gallon or a thousand gallons on the handle it won’t make a difference. How much will stay on the handle? In other words, how thick will the liquid coating be? The answer: Not very thick. Gravity and surface tension will make sure of this. Now let’s look at a carpet fiber – in many cases, thinner than a human hair. How much of your encap will adhere to the vertical fiber? The answer: A very thin microlayer. So why do a test that uses chemical full-strength up to a 1/4” thick in a glass when in the real world you never get anywhere close to that. Why use a test designed to market a feature, not the reality of real world usage of the product?

Imagine how thin the polymer is on this trilobial shaped carpet fiber magnified at 650x.

The product used in real world conditions will not cement soil to the fiber. If poured in a glass the product may dry rather hard and would seem to not be easily removed. But again, in the real world the layer of polymer is so thin that it has to be exceedingly strong to encapsulate the soils and fibers when the polymer in real use is under a micron thick. So naturally, if you take this very strong polymer and enlarge the thickness of the coating like in the glass trick thousands of times thicker than in real world applications, then its strength would also increase making the test inaccurate.

Surround products may fail the dry down marketing test. But that’s Ok; the test was designed to have competitors’ products fail. Surround would also fail if you filled your cars radiator with it, as it was never designed and manufactured to be used that way. However, when used in the proper and designed for purpose, Surround exhibits excellent encapsulating properties. The majority of our new T2H Hybrid Polymer will in most cases vacuum off of the fibers in 3 to 6 vacuum cycles. This could be a week in an office building or several weeks in a home.
