Applying a ceramic coating or paint sealant over contaminated paint is one of the most common mistakes in the detailing and coating industry — and one of the most expensive to correct after the fact. The invisible layer of polishing oil, silicone from old wax, and residual product that sits on automotive clear coat after a detail session will prevent the coating from bonding correctly, leading to premature failure, spotting, and uneven performance. Cleaning it off before application is not optional.
Duz-All Clear Coat Cleaner 16 oz (SKU P-40-P) from Polishing Systems Inc by Duz-All is the dedicated pre-coating and pre-correction paint prep spray. It strips the contamination layer from clear coat — wax residue, polishing oils, silicone from panel wipes and spray detailers, and general product buildup — leaving a clean, oil-free substrate ready for whatever comes next: correction, coating, PPF, or sealant application.
What Duz-All Clear Coat Cleaner Is
Duz-All Clear Coat Cleaner is a paint prep spray formulated to remove surface contamination from automotive clear coat without affecting the clear coat itself. It strips the invisible residue layer that polishing compounds, spray detailers, silicone-based products, and old wax leave on paint — the layer that conventional car wash does not fully remove and that interferes with coating adhesion and paint correction accuracy.
Key Features and Why They Matter
- Strips polishing oil and silicone — the contamination types that most affect ceramic coating adhesion. A wipe-down with Duz-All before coating application is the difference between a coating that bonds for its rated lifespan and one that degrades early.
- Clear coat safe — removes surface contamination without stripping or hazing the clear coat underneath. This is prep chemistry, not a correction compound.
- Removes wax and sealant residue — essential before paint correction work, where wax residue on the surface can load polishing pads and interfere with compound cut rate and clarity of results.
- 16-oz spray format — practical working size for individual detailers, mobile coating installers, and body shop technicians doing prep work on individual vehicles. Spray-and-wipe application makes it fast to use section by section.
What This Is NOT For
Duz-All Clear Coat Cleaner is a surface prep and contamination removal product — it is not a paint cleaner or correction compound, and it will not remove swirl marks, scratches, or paint defects. It is not a car wash soap and should not be used as a substitute for proper washing before paint prep. Do not use on matte or satin finishes without testing — matte clear coats can respond differently to surface chemistry than standard gloss clear coat. Do not allow the product to dry on the surface — always wipe clean while wet.
Who Uses This
Ceramic coating installers use a paint prep spray as a required step in their pre-coating workflow — after machine polishing and before coating application, every panel gets a prep wipe to remove polishing oils. Auto body shops use it to strip silicone and wax contamination from panels before refinishing — silicone contamination in a paint booth causes fisheye defects in fresh paint. PPF (paint protection film) installers use it to ensure a clean substrate before film application. Mobile detailers use it as a final prep step before applying sealant or wax to ensure the protection bonds to clean paint. The 16-oz size is right for individual installers and mobile operators.

How to Use
- After washing: Use Duz-All Clear Coat Cleaner after the vehicle has been washed, clayed if needed, and machine polished if correction was performed.
- Apply to panel: Spray directly onto a clean microfiber panel wipe towel or directly onto the panel section.
- Wipe: Work across the panel in straight, overlapping passes with a clean lint-free microfiber. Fold the towel frequently to expose clean sections.
- Immediately buff: Follow with a dry side of the microfiber to fully remove the product before it dries. Do not allow the product to dry on the surface.
- Proceed to coating or protection: Work panel by panel, applying protection immediately after prep to avoid re-contamination from handling or environment.
Why Buy This vs. Using IPA (Isopropyl Alcohol)
IPA wipes are a common substitute for dedicated paint prep spray, and they work for removing polishing oils. Duz-All Clear Coat Cleaner is a purpose-formulated product designed specifically for the automotive clear coat prep step — addressing the range of contamination types including silicone, wax, and oil residue more comprehensively than IPA alone in some application contexts. For coating installers doing high-volume professional work, a dedicated prep product provides a consistent, documented prep step.

Frequently Asked Questions
Is Duz-All the same as an IPA (isopropyl alcohol) panel wipe?
Duz-All Clear Coat Cleaner and IPA panel wipes both serve the paint prep function of removing surface contamination before coating or protection application. Duz-All is a purpose-formulated automotive paint prep product with a chemistry blend designed specifically for the range of contaminants present on automotive clear coat after a detail session. The specific performance comparison depends on the contamination type and the coating system being applied — consult your coating manufacturer’s recommended prep protocol.
Do I need to use this before every wax application?
For best wax and sealant bonding, stripping the old wax layer and any intervening contamination before applying fresh protection is standard practice. Applying new wax over old wax reduces the bonding quality and dilutes the new product. Duz-All Clear Coat Cleaner used before each wax application ensures the new product contacts clean paint directly.
Can I use this on wrapped vehicles or vinyl?
This product is formulated for use on automotive clear coat. Vinyl wrap and PPF have their own surface chemistry — consult the film manufacturer’s recommendations for approved prep products before using any paint prep spray on wrapped or filmed surfaces. Some prep chemistries can affect vinyl adhesion or clarity.
How much surface area does 16 oz cover?
Coverage depends on application rate and panel wiping thoroughness. For a typical passenger car detail prep workflow, 16 oz covers approximately 2–4 full vehicle prep sessions depending on vehicle size and application technique. For higher-volume use, the 1-gallon size provides significantly more coverage at a lower per-ounce cost.
Should I use this before paint correction or after?
Use Duz-All Clear Coat Cleaner after machine polishing and before applying the final protective coating or wax. The pre-correction wash and clay bar stage handles gross contamination before paint work; the Duz-All prep wipe addresses the residual polishing oils and product residue that remain on the surface after the correction stage — the contamination that directly affects coating adhesion.
