Klasse All-In-One is a product that has been on the market for a few decades, and although it has a decent cult-like following among some enthusiast, it is usually not mentioned enough among all enthusiasts. Long term users will notice Klasse’s power as a “cleaning sealant”, and its longevity.

We will talk specifically about the All-In-One product. Klasse also has a pure sealant product, Klasse High Gloss Sealant Glaze, that does not contain cleaners and has truly outstanding longevity. Ivan Rajic from LUSTR Auto Detail in Chicago has a great article on the Klasse High Gloss Sealant Glaze and the tricks on how to use it.

While Klasse AIO is marketed as a chemical cleaner containing no abrasives, when used with the correct pad under the Dual Action Polisher it that Klasse AIO will correct slightly on softer paints, which is awesome. Since Klasse AIO is a very strong and long-lasting sealant, having some cleaning properties makes it double as useful.

This vehicle had never been waxed, much less washed properly, in 10 years. We were focusing on the interior, but decided to use Klasse AIO and an orange pad instead of just a sealant on a black pad. This is severely swirled paint, but notice even a little Klasse AIO makes quite a difference! We polished this entire car with this combination in under an hour. Here is our test section on the hood:

Notice the left side of the truck. Although far from perfect, for little more than the effort to wax the vehicle using the polisher, the results are quite outstanding:

This Acura was fairly new and had very few swirls. All that was needed was some Klasse AIO on a white pad under the Porter Cable Polisher and about an hour. The result is very good clarity and reflections for a fraction of the time. If you start early enough, before you get swirls on your new car, Klasse AIO is all that is needed to get the clarity the car should have.

Although KAIO is a great sealant, it is always fun to add more layers. You can layer any further protecting product over KAIO without issue. Eric Schuster from Envious Detailing in California writes about Layering Paint Sealants in this article. Optimum Opti-Seal or Dodo Juice Red Mist Tropical is a great choice. The interior carbon fiber in red Ferrari below received Supernatual Carnauba Wax over the KAIO for extra depth, although pictures were taken before the wax was applied. See our review of Dodo Juice Supernatural wax here.

Here we will go over some ways to use Klasse AIO specifically. Other than the obvious uses on exterior paint, Klasse AIO can be used in areas that might not seem so obvious.

Windows: Klasse AIO helps to deep clean window surfaces, both sides. As it hazes it can be wiped off clean from the glass, removing stubborn VOC buildup from inside front windscreens, smudges, and fingerprints. Beware, it will take some effort to work it into the glass, and it will probably take a second application, but will leave a super slick glass surface that resists getting dirty again. Once Klasse AIO sets, or “flashes”, it can be stubborn to remove. Meguiar’s Glass Cleaner is the best glass cleaner we have used, and another great multi-purpose product that does much more than just clean glass. Use Glass Cleaner here to get the rest of the Klasse AIO off the glass. It will not remove the protection. If anything, reapplying Klasse AIO the second time you will not have to work it in as hard, will use much less product, and can wipe off sooner and more clean. Be careful on tinted windows. Klasse AIO is advertised to have no abrasives, but the definition of this is not standardized. The cleaners could impart scratches to your window film. Test on an inconspicuous area if possible (there are not many inconspicuous areas on windows!). We have used Klasse AIO successfully on ceramic and high quality film as well as the cheap tint my Honda had. No scratches so far, but still do a test section on yours first and make sure it will not scratch your film before using!!

Clear engine covers similar to an Audi R8, rear engine bay glass like on Ferraris and this NSX, benefit greatly from Klasse AIO on their clear portions. Klasse AIO will help deter oil vapor buildup and other nastiness the engine lives among.

Mirrors: Klasse AIO is great on the rear view mirror inside. Use a MF towel and fold an edge to get into the crevice around the mirror glass and the plastic trim. Door mirrors benefit from Klasse AIO’s cleaning properties and water repellency. I find my mirrors fog up less with Klasse AIO, although Klasse AIO is not an anti-fog agent.

Interiors: Apply sparingly onto smooth plastic trim, work in, and wipe off. No need to let haze. Wood trim, metal-looking trim, and plain black plastic trim looks deeper, more even with Klasse AIO and feels slick. I have used it on my “soft-touch” rubberized coating in the buttons of my Audi. Worked great! Radio controls, Nav screens, Gauges, AC controls, buttons, trim around steering wheels, shift knobs, shift gates, center consoles, upholders, sunroof switch clusters, overhead lighting, grab handles, any hard smooth surface can get Klasse AIO wiped on and off, except the dash panel. The amount of sun baking the top of the dash gets will make any Klasse AIO in the grain turn white and will be visible. I will use a General Purpose MF towel, dab a corner with some Klasse AIO, rub with this corner and rub clean with the rest of the towel, changing the towel after a few sections. Go over one last time with a clean towel. Klasse AIO should not damage leather, but try to keep a tidy edge. Klasse AIO is great for cleaning seat belt buckles, and helps keep them clean from thereon after.

Here we are applying Klasse AIO to all carbon surfaces in the cockpit:

Not bad for a few minutes with some Klasse AIO and a terry cloth applicator or foam applicator:

Door jambs feel nice and silky after an application of Klasse AIO. If your trunk lid and hood are clean enough, apply Klasse AIO to them as well. Klasse AIO can last longer than most spray sealants, and cleans further as you apply.

Wheels: Use as a light bug and tar remover for the barrels of the wheels. Seals wheels pretty good.

Engine Bay: Use Klasse AIO on any and all smooth surfaces. Carbon trim, or aluminum structural members are good candidates for Klasse AIO:

Driver side airbox has Klasse AIO, passenger side airbox does not. Even on pristine carbon, the addition in gloss is noticeable.

You will want to keep KAIO off textured plastics as much as possible. I wouldn’t go as far as taping my mirrors to apply KAIO with the Dual Action Polisher, but I will keep a good eye on my edges around those areas, or just apply by hand. Any sealant or wax with a cleaner component in it will turn white as it bakes in the sun. We have all seen white marks on trim from previous wax applications, or caked into crevices now white and very fond of the vehicle. This is the most commonly seen sign of poor application as it stands out in most colors and typically is just as bad throughout the rest of the vehicle. KAIO will leave a white residue if not removed. It becomes more fond of the trim with more sun exposure and time. Black WOW does a great job at breaking down white stained trim. Fade2Black works for less severe cases. Either will require various applications over time depending on the severity of the stains.

Klasse AIO works by cleaning and protecting in one step. It requires mechanical work to put on and get off. It layers very thin and strong. But it must be free of residue. Klasse AIO is a unique product in that it has one of the widest ranges of usage of any detailing product, and it does all of them quite well. It definitely has a space in anyone’s detailing kit or product arsenal. And once you have it, look into other places where KAIO can be useful. I use it inside the house as well. But that is the topic for another article 😉
