Koch Chemie Finisher InsideUp Interior Cleaner

Koch Chemie Finisher InsideUp is an interior cleaner you can use on nearly every surface in the cabin: plastic, upholstery and fabric materials. The cleaner dissolves dirt, grease and everyday grime without attacking the material, and leaves no sticky residue or artificial shine behind. That matters, because many interior cleaners give plastic a glossy 'showroom' look that attracts dirt again quickly. This product does the opposite: the interior looks fresh, clean and natural, the way it's meant to. Because it works across multiple materials, one bottle covers the dashboard, door panels, fabric upholstery and floor mats, instead of reaching for a separate product for every surface. This interior cleaner is the logical first step in an interior detail: you start here to lift the bulk of dirt and grease before moving on to targeted products for plastic care or leather care.

What's inside

One 500 ml bottle of Koch Chemie Finisher InsideUp interior cleaner, ready to use.

Why this product

• Works on plastic, upholstery and fabric materials throughout the interior, from dashboard to door panels

• Dissolves dirt, grease and everyday grime without attacking the materials

• No sticky aftertaste or artificial shine, so there's no extra film that attracts dirt

• Keeps a natural, matte look instead of a glossy showroom effect

• One product for multiple interior surfaces, so you don't need to keep switching

• Suitable as the first cleaning step before targeted care for plastic or leather

How to use

1. Vacuum the interior first, so you do not rub loose dirt or grit across the surface while cleaning it.

2. Spray InsideUp onto a microfiber cloth or directly onto the surface, avoiding direct spraying onto switches, buttons and screens.

3. Work panel by panel with light pressure, letting the cleaner dwell briefly on stubborn dirt before wiping it fully away.

4. Wipe off with a clean, dry cloth, and use a separate cloth or soft brush for fabric upholstery to work the dirt fully loose.

For the next step, grab a detail brush for the seams, a plastic care product for the dashboard, and a glass cleaner to finish the windows.
