Hi Mark, thanks for your question, and here's the reason: The Super Plush Towels pick up double the residue than the less expensive, Chinese towels. That makes the residue more difficult to remove with those towels, and easy to remove with ours.
We want customers to have a great experience with our products. Since the Machine SuperWax is actually a polymer sealant with resins and aminos, which protect for a long time, it's harder then the Buttery Wax to remove.
Problem: The substantial nature of the product makes it difficult to remove with an entry level towel. We tried it, and it took twice the effort!
So, instead of getting, "Hey, this stuff is tough to remove," feedback, we suggested using our Super Plush Towel, and people have had good experiences!
Thanks for asking!
