A follow-up to my ShMiTT testing
I am still using the ShMiTT as the primary washing tool for my personal vehicles. Performance is unchanged and durability is looking very good. After 7.5 washes, the initial pinhead tear has doubled in size but that's the only damage so far. That is far better than I had expected. The ShMiTT also requires very little maintenance. I only have to rinse it out in the sink and it’s practically new again. I can reuse it over and over without having to throw it into a machine wash. My cotton chenille mitts require machine washing after each use, so I have to keep several on hand in case I don’t have time to do a load of laundry.
While the ShMiTT appears to be a very nice tool for traditional hose washing of well maintained car finishes, the reviews become a little more mixed when dealing with neglected cars or rinseless washes. In those cases, the ShMiTT doesn't "feel" as good as a cotton chenille mitt. This is a strictly subjective statement that I will try to explain here -
To put you mind at ease, I saw no evidence that the ShMiTT caused any marring of paint. The end results were the same when directly comparing a ShMiTT against a cotton chenille mitt. When used on a slick surface (e.g. freshly waxed), the ShMiTT glides effortlessly. But when you switch to a neglected car, the ShMiTT grabs and hops along the surface and becomes more difficult to use than cotton chenille. The difference is even more pronounced when using rinseless washes.
The closest comparison I can provide is that of a California Water Blade. For those of you who have used a CWB, you know that it is a silicone blade that you use like a squeegee. It does a great job of removing water from a freshly washed vehicle, but it makes a horrendous squeaking sound and sometimes hops along the surface. No damage is done, but it sure sounds and feels like something bad must be happening. I have the same reaction when using the ShMiTT with neglected cars and rinseless washes.
Regarding the rinseless washes, the ShMiTT does not seem to work quite as well as cotton chenille. I prepared two buckets of Optimum No Rinse solution (I used the Optimum product instead of Protect All’s QEW because I find NR to be the slicker of the two). One bucket was used for rinsing out mitts, while the other was considered the fresh wash bucket. I washed half a moderately dirty car with a ShMiTT and the other half with a cotton chenille mitt.
Both mitts shared the same two buckets of solution. While nothing bad happened with either mitt, I didn't like how grabby the ShMiTT felt while moving across the paint. It also left a lot more wash solution behind on the finish, making the drying process more difficult (takes a longer time with more towels needed). [In this photo, the passenger side of the vehicle was washed using the ShMiTT.]
Since the moderately dirty car did not have a fresh coat of wax, I repeated this test on the trunk lid of a freshly waxed car and observed the same results. So, my initial observation is that a ShMiTT can be used with rinseless washes, but it doesn’t appear to be as user friendly as cotton chenille. It did, however, come completely clean just from rinsing in warm tap water. The chenille mitt required a machine washing.
My overall opinion thus far is that the ShMiTT is a fine wash tool for people who really take good care of their cars. Since I happen to fall into that camp, I plan to continue using the ShMiTT as my primary washing tool. However, I will switch back to cotton chenille during the winter months for rinseless washing.
