Koch Chemie Top Star Interior & Exterior Dressing 1L

Koch Chemie Top Star is a silicone-free dressing for plastic and rubber surfaces, inside and outside the car. Treated panels, rubber seals, and exterior trim recover a cared-for appearance with a natural satin sheen that does not look wet or overdone.

The silicone-free formula leaves no greasy or tacky residue, making Top Star safe to use in the engine bay, on exterior trim, and across interior plastics without any risk of contaminating nearby paintwork. Built-in UV protection helps guard surfaces against drying out, fading, and cracking over time.

The 1-litre format suits professional detailers or anyone who regularly treats multiple vehicles. Applied sparingly, a single bottle goes a long way.

Why this product

• Silicone-free formula: leaves no greasy or tacky film, surfaces feel completely dry and clean after treatment

• Suitable for both interior and exterior plastic, rubber, and trim, including the engine bay

• Long-lasting results from a concentrated formula in a large 1-litre professional size

• Safe near paintwork: no silicones that could interfere with future bodywork or touch-up jobs

How to use

1. Clean the surface thoroughly (Remove dust, grime, and any residue from previous products using a suitable interior or exterior cleaner. Let the surface dry completely before moving on.)

2. Apply a small amount to an applicator pad or microfibre towel (Use sparingly: a few drops per panel is enough. Too thick a layer will not absorb evenly and can leave streaks.)

3. Work the product evenly across the surface (Use circular or straight strokes to spread Top Star across the plastic or rubber, making sure you cover the entire area consistently.)

4. Buff off any excess with a clean microfibre towel (Remove any surplus product with a dry microfibre cloth. The surface is ready to use immediately. For a more matte result, dilute the product lightly with water before applying.)
