Koch Chemie (FSE) Finish Spray Exterior | QD Limescale Remover

A car quick detailer spray that does more than boost gloss. It actively removes fresh water spots and limescale before they become a problem.

Koch Chemie (FSE) Finish Spray Exterior is not your standard quick detailer spray. It is built specifically to deal with fresh water spotting and light limescale marks on exterior surfaces before they become something more serious.

Anyone who washes regularly knows the issue. You rinse the car, miss a section, or the sun gets to it first. Suddenly you have mineral spots sitting on paint or glass. FSE is designed for exactly that moment. It breaks down fresh mineral residue safely, lifts it cleanly, and restores clarity without dragging you into heavy acid cleaners or polishing.

At the same time, it behaves like a proper car quick detailer spray. It enhances gloss, deepens colour slightly and leaves the surface smooth and streak free. There is no greasy film, no smearing on glass, and no heavy build up.

Safe for paintwork, exterior plastics and glass, it fits perfectly into maintenance washes or post wash touch ups. Spray it on, wipe it off, and the surface is clean, sharp and protected again.

Note: Use promptly on fresh water spots for best results.


Features:

  • Removes Fresh Water Spots and Limescale: Targets mineral deposits before they etch or permanently mark the surface.
  • Clean, Maintain and Preserve in One Step: Saves time by combining light cleaning, gloss enhancement and protection.
  • Restores Colour Depth and Clarity: Leaves behind a smooth, brilliant and streak free finish.
  • Safe for Exterior Automotive Surfaces: Suitable for paintwork, glass and exterior plastics.
  • Ideal Maintenance Quick Detailer Spray: Perfect for use after washing or whenever fresh water spotting appears.

 

Directions:

  1. Spray evenly onto affected area or directly onto a clean microfiber cloth.
  2. Gently wipe the surface, allowing the product to break down water spots and residue.
  3. Buff off any remaining product with a dry side of the cloth to achieve a clean, streak free finish.

Precaution: Do not use on hot surfaces or in direct sunlight. Do not use on acid sensitive surfaces. Test compatibility on an inconspicuous area before use.

    BRILLIANT PRODUCT!!

    Koch Chemie FSE is incredibly easy to use and a great maintenance product for ceramic coatings. I use it every few washes to restore slickness and boost hydrophobic performance. It's also excellent on windows, leaving them clear, slick, and highly water-repellent.

    Super underrated product

    This stuff is awesome. Great for a drying aid every few washes to remove those minor water spots almost like a mini decon and ceramic coating revival. The gloss it leaves and how easy it is to use are also worth mentioning
