To get faded car interior plastic back to black, start by removing the dulling layer (dust, skin oils, cleaner residue, and oxidation), then restore color with a dedicated plastic trim restorer. The best results come from careful prep, thin product application, and proper curing time so the finish looks even instead of greasy.
Vacuum crevices first so grit doesn’t scratch the surface. Wipe the trim with a quality interior cleaner or an all-purpose cleaner diluted for interiors. Use a soft detailing brush to work cleaner into texture and seams, then wipe dry with a clean microfiber towel. If the plastic still looks chalky or uneven, lightly repeat the process—restorers bond better to clean, residue-free surfaces.
Many “shiny” interior dressings leave silicone residue that blocks even restoration. Follow cleaning with a final wipe using a residue-cutting prep (such as an interior-safe degreaser or panel-prep style wipe), then let the surface fully dry. This step is often the difference between a patchy look and an even black finish.
Use an applicator pad or foam sponge and apply a small amount at a time. Spread it evenly, working it into the grain. Avoid flooding seams or textured areas, which can dry blotchy. Let the first coat settle, then add a second light coat only where needed. Buff lightly with a microfiber towel to level the finish and remove excess so it dries to a clean, factory-like satin.
Keep the interior dry and avoid touching the restored areas until cured (check the product directions). Park in the shade when possible; UV exposure is what fades black plastic fastest. Ongoing gentle cleaning helps the restored color last longer.

On interior trim, a good restorer can last for months because it’s protected from rain and harsh wash chemicals. Longevity depends on UV exposure, how often the surface is cleaned, and whether excess product is buffed off after application.
