Create a clean slate for your wax, sealant, or coating

McKee's 37 Coating Prep Auto Wash is a powerful detergent that strips remaining traces of previously applied waxes and sealants, leaving your vehicle squeaky clean for the next step in detailing. By breaking down old waxes and silicone oils, the next step you perform in the detailing process (clay, polish, coat) will produce superior results. McKee's 37 Coating Prep Auto Wash is infused with highly refined alkaline detergents that effectively deep clean your paint without drying it out. Formulated without acids or phosphates, you can trust that Coating Prep Auto Wash is 100% safe for all exterior surfaces. This high-foaming formula encapsulates dirt and grit particles, helping to prevent wash-induced swirl marks and scratches.

Create mountains of foam with McKee's 37 Coating Prep Auto Wash! This surface-safe formula can be used the traditional method with a 5-gallon bucket, OR with a Foam Gun or Foam Cannon!

DO NOT WASH CAR WITH DISH SOAP. Period! This old-school method of prepping the surface by supposedly stripping previously applied coats of wax does more harm than good. You see, dish soap is formulated to tackle grease and grime from last night's lasagna, NOT waxes and silicone oils found in car care chemicals. As a result, dish soap leaves a film on the surface that will interfere with the polishing process. Dish soap also wreaks havoc on rubber exterior trim, leaving it dry and brittle over time. Worst of all, dish soap is more likely to leave water spots! There's a superior alternative - McKee's 37 Coating Prep Auto Wash.

It's common knowledge that the cleaner the paint, the better your wax, sealant, or coating will adhere. That's why we formulated a special auto wash that's 3x as powerful as a regular soap, helping break down and remove trace residues of previously applied waxes and sealants. This improves the performance of your clay bar or polishing compound. Washing your vehicle with McKee's 37 Coating Prep Auto Wash is the first step in a proper detail.

McKee's 37 Coating Prep Auto Wash is unlike any other soap on the market. The first thing you'll notice about this unique formula is the viscosity. Unlike gloss-enhancing auto wash formulas, McKee's 37 Coating Prep Auto Wash forgoes thickening agents and fruity fragrances that would otherwise hinder the alkaline detergents from doing their job - removing trace residues of previously applied waxes and cutting through thick layers of road film.

If you detail for a living, chances are most of the vehicles you work on have not been washed in months, or even years! A regular auto wash is not strong enough to cut through thick layers of filth and road film. McKee's 37 Coating Prep Auto Wash and its alkaline formula cuts through road film, saving you time and effort as you wash the vehicle. Whet's more, McKee's 37 Coating Prep Auto Wash rinses freely, leaving the paint clean, shiny, and ready for the next step in detailing.

Leave the dish soap in the kitchen, and instead stock your detailing cabinet with McKee's 37 Coating Prep Auto Wash.

    Removes everything even road film!

    This is my go-to wash for everything from Ceramic prep to daily driver before applying any protection. In a pre-wash with a foam cannon when I’m just rinsing it off you can see the road film just washing off before doing a contact wash. It works great!

    Coating Prep Auto wash

    Ceramic coated mustang needed a good wash and extra kick to clear away old waxes. Prep wash cleaned it all and got me back to the original coating shine and depth. Excellent product.

    Great soap for cleaning coated vehicles and those that have been through a harsh winter. Works well in foam gun as well! Rinses away easily and when foamed on has a good dwell time

    Great for decontamination

    This soap is great to use before you apply a new LSP on the car. It will remove old wax/sealant and leave the surface ready for claying, then polishing, and finally a new LSP. It can also be used on ceramic coated cars after the winter to remove a lot of the stuff that bonded to the paint during the season they put salt and who knows what else on the roads. I always wear gloves when using this product, its high pH is not very nice for the skin.
