Washing Plastic Trim the Right Way
Plastic trim is often overlooked during washing, but caring for it properly can make your entire vehicle look newer. Whether it’s textured bumpers, mirror caps, or door moldings, washing plastic trim the right way prevents fading, streaks, and that dreaded chalky look. In this guide, you’ll learn how to clean and protect your trim safely — without leaving behind greasy residue or unwanted shine.

Why Plastic Trim Needs Special Attention
Exterior plastic trim is porous and textured, which means it traps dirt and collects residue that paint won’t. Over time, sunlight, road grime, and detergents can dry it out, turning it gray or chalky. Unlike paint, you can’t polish trim to restore it — so prevention is key. Using the right soap and protection keeps your trim dark, clean, and factory-fresh.

The Best Soap for Washing Trim
Since trim has more texture than paint, it’s important to use a soap that rinses clean and doesn’t leave behind gloss or residue. The Super Soaper is ideal — it’s slick, pH-neutral, and residue-free. It lifts dirt and oils without drying out the plastic or altering its natural finish.
Unlike shampoos that contain gloss enhancers, The Super Soaper maintains the natural look of trim while preparing the surface for a dressing or protectant afterward.

- Pre-rinse thoroughly: Remove loose dirt and debris using low to medium pressure water.
- Pre-soak with foam: Mix 2 oz of The Super Soaper per gallon in a foam cannon or pump sprayer and let it dwell for 2 minutes to break down grime.
- Agitate gently: Use a soft brush or microfiber towel to clean textured trim. For deep grooves, a soft detailing brush helps lift dirt from pores.
- Rinse completely: Flush away all soap residue to prevent streaks or residue buildup in texture.
- Dry with care: Pat dry with a clean microfiber towel. Avoid dragging to prevent lint or streaks.
What to Avoid When Washing Plastic Trim
- → Avoid strong APCs or degreasers unless absolutely necessary — they can fade trim over time.
- → Don’t use waxes, sealants, or dressings meant for paint — they may leave white stains or shine buildup.
- → Avoid scrubbing with stiff brushes or pads — textured plastic can scratch easily.
- → Never use tire shine sprays on trim — overspray can stain or cause blotching.
How to Protect Trim After Washing
Once the trim is clean, protect it to prevent fading and discoloration. All Dressed Up is the ideal water-based dressing that restores color and adds UV protection with a factory-style matte finish — not greasy shine. It can be used inside and outside, making it perfect for bumpers, moldings, and dashboards alike.
Apply with an All Blacked Out Applicator to spread evenly without oversaturating the surface.
Pro Tips for Long-Lasting Trim
- → Wash trim first during your wash routine to prevent soap drying on textured surfaces.
- → Apply All Dressed Up monthly for consistent UV protection.
- → Always store your car out of direct sunlight to slow UV damage.
- → Avoid using silicone-based dressings that attract dust and grime.
