Koch Chemie Pol Star is a pH-neutral interior cleaner with a built-in fabric protection formula designed for cleaning and protecting leather, Alcantara, upholstery, and carpets in automotive interiors. The fine-pored foam penetrates deep into fabric fibers to lift and encapsulate dirt, allowing it to be wiped away cleanly without overwetting the surface or leaving water marks behind.

Importantly, Pol Star preserves the original waterproofing of treated fabrics during cleaning rather than stripping it away, which is a common problem with harsh interior cleaners. The built-in protection formula also helps treated surfaces resist rapid re-soiling after cleaning, keeping interiors looking cleaner for longer between details. Safe on all interior fabric types including the delicate Alcantara surfaces found in premium and performance vehicles.

If you are looking for a professional interior fabric cleaner that protects as it cleans, a Koch Chemie upholstery and carpet cleaner that is safe on leather and Alcantara, or a pH-neutral interior cleaner that does not strip waterproofing from treated fabrics, Pol Star is a precision product designed specifically for professional interior detailing work. Available in 1L and 5L.

Koch Chemie Pol Star Usage

Pol Star is Koch Chemie's interior fabric, carpet, and leather cleaner — ready-to-use, designed for extraction machines as well as hand cleaning.

• Hand cleaning: Spray onto fabric/carpet, agitate with interior brush, blot with microfiber or extract with wet/dry vac.
• Extractor use: Load into the solution tank (no dilution for Pol Star — it's ready-to-use).
• Leather: Safe for general cleaning. For dedicated leather care, use Leather Star.

Frequently Asked Questions

Can Koch Chemie Pol Star be used in a carpet extractor?

Yes — Pol Star is extractor-compatible. Load directly into the solution tank (it's ready-to-use, no dilution). Agitate heavy stains first with a brush, then extract.

Is Koch Chemie Pol Star an APC?

Not quite — Pol Star is specifically formulated for interior fabric, carpet, and leather. It's not intended for exterior hard surfaces or heavy degreasing. For those uses, Green Star (GS) or MZR are the correct APCs.

Koch Chemie Pol Star vs Fresh Up — are they the same thing?

No. Pol Star is a cleaner — it removes dirt, stains, and body oils from fabric/leather. Fresh Up is an enzymatic odor eliminator — it breaks down odor molecules (smoke, pet, food) but doesn't clean. For a smoky fabric seat, use Pol Star to clean, then Fresh Up to eliminate the smell.
