Here's an article I wrote in a local Porsche magazine:
A Wash Is Just A Wash....Right?
If there's one aspect of detailing that I'd say is most important yet overlooked, it would be washing. Think about it; you pay hundreds, maybe thousands, to get a proper detail. You're given a car that is almost flawless and has never looked so great. But now what? What are you going to do to keep it looking this way? Well, this is where it gets puzzling. Do you take it to the car wash, pay a detailer at the office, or do it yourself? The first two choices are the least labor intensive. I mean, how hard is to take the car to the local Chevron or Auto Spa, hand over the keys to some guy you don't know, and a latte and 20 minutes later, your car is shiny and clean. Or, let's step it up a notch and hand it over to the local wash guy that makes his rounds at your office. Surely he must do a much better job, and you never left the office. Well my friends, this convenience comes at a cost. The cost may be swirls, scratches, a dent that you know wasn't there before but you're being told it was. Who knows what else.
What I'm trying to lead you to is how simple and rewarding a wash can be if you have the correct technique and products. So let's start with most basic of ingredients, soap. There's a reason you see soaps specifically made for automotive finish. Paint has its own natural oils that are there to maintain gloss, and in some areas, flexibility.
By using dish soap, cheap automotive soap, or petroleum-based soaps, you're robbing the finish of its oils.
The solution is using a high-quality, pH balanced soap that is gentle on the finish and is effective at removing grime.
You'll notice one main difference between a high quality soap opposed to an inferior one: how little product is used. There are several high quality soaps from P21S, Sonax, Lumiere, einszett, etc. Spending a little extra on the soap also saves the wax on the car from diminishing prematurely.
What you wash the car with is just as important as what soap is used. Your choices are wide: synthetic sheepskin, microfiber, foam sponge, or my favorite, all-natural Australian or New Zealand sheepskin. Synthetic sheepskin is a cheaper alternative to the real version. I find the nap to become stiff, and almost brillo-like, after a few washes. Microfiber is soft in the beginning but traps dirt; over time, you end up rubbing the embedded dirt into the finish causing scratches. The foam sponge isn't all that bad, but once again, you run the risk of dirt getting trapped in the cells of the sponge. The reason why I prefer natural sheepskin is that it's the softest of all choices.
Natural sheepskin is very gentle and won't harm the finish.
Now that you've got the right soap and mitt, what will you dry with? Your choices are simple: cotton bath towel, synthetic chamois, natural chamois, microfiber drying cloth, or air dry. The
cotton towel is old technology and should be left in the shower. The
nap of the towel will actually scratch today's soft automotive finish. Synthetic chamois trap dirt over time and scratch the finish. Anyone who's used a natural chamois can attest to its glue-like suction power, not to mention the oil used in the tanning process strips the wax from the finish. The
newest technology replacing chamois is microfiber drying cloths. The soft microfiber allows you to feel the finish and know when you need to polish or clay again. The
ideal way of drying is to air dry or force air dry. If you have the convenience of using de-ionized water, you can simply air dry or use a forced air dryer such as an Airmax. The beauty of the Airmax is that it has a dual stage filtration system, heated air, and dual stage motors. This yields you clean and powerful air in a compact unit. The result is drying without ever touching the finish.
Finally, the water you use is important. How many times do you find yourself chasing the sun and working fast to prevent water spots when washing? This not only leads to potential damage, but it simply takes the fun out of caring for your car. Enter de-ionized water. DI water systems simply take the Calcium and Magnesium ions, the hard water ingredients, and exchange them into Hydrogen and Hydroxide ions. Result…pure H2O. CR Spotless makes an excellent system. The units start at $299.[SUP]99[/SUP]
DI Water gives you pure water without any dissolved solids. Translation…no water spots! Even in direct sunlight.
I hope this article has shed some light on how important such a simple task can be. Stay clean my friends!
