Expert Notes

Koch-Chemie Headlight Polish 1 is the cutting stage in Koch-Chemie’s headlight restoration system. It is designed for heavily weathered PMMA plastic headlights where oxidation, yellowing, sanding marks and surface scratches need proper machine correction. This is not a quick wipe-on lens cleaner. It is a heavy cut polish used after sanding or on badly degraded lenses, usually with a rotary machine and either a Heavy Cut Pad or lambswool pad. Headlight Polish 1 removes the defects and sanding marks, then Headlight Polish 2 is used afterwards to refine the finish and restore maximum clarity. Heat control is important because plastic headlight lenses can distort or mark if worked too aggressively.

Perfect For / Suitable Surfaces

  • PMMA headlights
  • Plastic headlight lenses
  • Car headlights
  • Truck headlights
  • Motorcycle headlights
  • Yellowed headlight lenses
  • Weathered headlight lenses
  • Sanded headlight lenses
  • Oxidised plastic lenses

Caution: Designed for PMMA plastic headlights, not glass, paintwork, interior plastics, screens or general trim. Control heat carefully during machine polishing and protect surrounding paint, trim and rubber before use.

How To Use

Headlight preparation

  1. Clean the headlight thoroughly before polishing.
  2. Mask surrounding paintwork, grilles, bumpers and trims.
  3. Check the lens material and condition before starting.
  4. Sand the lens first if oxidation or defects require it.
  5. Use suitable abrasive grades according to the level of weathering.
  6. Remove sanding residue before polishing.
  7. Shake Headlight Polish 1 before use.

Machine polishing

  1. Apply Headlight Polish 1 to a Heavy Cut Pad or lambswool pad.
  2. Spread the product across the lens before increasing speed.
  3. Polish in a crosswise pattern with a rotary polisher.
  4. Use medium speed and medium pressure.
  5. Keep the pad moving to control heat.
  6. Check the lens temperature regularly.
  7. Remove polish residue with a clean microfibre cloth.
  8. Repeat only where sanding marks or defects remain.

Refining stage

  1. Inspect the headlight after the cutting stage.
  2. Switch to Koch-Chemie Headlight Polish 2 for final finishing.
  3. Use the correct finishing pad for the second stage.
  4. Polish until the lens becomes clear and glossy.
  5. Remove residue fully after polishing.
  6. Apply suitable headlight protection if required.

Top Tip: Keep heat under control when polishing headlights. Plastic lenses are temperature sensitive, so use controlled pressure, keep the pad moving and do not overwork one area.

The Brand

Koch-Chemie

Koch-Chemie (often written Koch Chemie) is a German car care maker from Unna. Hans Koch, a trained carpenter unhappy with the vehicle care products of the time, began mixing his own polishes in his garage in 1968 and founded Koch-Chemie GmbH. The company moved to its Unna headquarters in 1971, developed its Star range in 1990, and has been part of the French Novarc Group since June 2017. It is one of the few companies in the trade that researches, produces and sells its own products, with development and production in Unna, and many of its products are tested and approved by car manufacturers.

At The Drivers HQ we stock Koch-Chemie online with UK delivery and in our Ilkeston shop. Our customers' favourites are Green Star, Gentle Snow Foam, Pol Star, Micro Cut M3.02 and One Cut & Finish P6.02.

Koch-Chemie products by job

Pre-wash and wash. Gentle Snow Foam is a pH-neutral, cherry-scented foam that does not attack waxed or sealed paint. Use about 20ml per litre of water in a foam sprayer, or 50ml in 10 litres as a hand-wash shampoo, and add 10 to 30ml of Green Star to the mix for an active foam on stubborn dirt and insects. Green Star is the alkaline universal cleaner: 1:5 to 1:30 for exteriors and engines, 1:10 to 1:20 for interiors and textiles. Never let it dry or use it on hot panels. Active Foam, Autoshampoo and Ceramic Effect Shampoo complete the wash range, and Magic Wheel Cleaner is the wheel cleaner.

Decontamination and preparation. Eulex and Eulex M remove adhesive and stains, Orange Power lifts adhesive, tree resin and rubber marks, and Panel Preparation Spray cleans the paint before polishing or coating.

Machine polishing. Koch-Chemie gives its machine polishes a cut and gloss rating, and Heavy Cut H9.02, Fine Cut F6.01 and Micro Cut M3.02 are silicone-oil-free. Heavy Cut H9.02 (cut 9.0, gloss 6.0) takes out deep scratches and sanding marks up to 1,200 grit, Fine Cut F6.01 (cut 6.0, gloss 7.0) removes wash marks and 2500-grade sanding marks, and Micro Cut M3.02 (cut 3.2, gloss 9.0) removes holograms, fine scratches and P3000 sanding marks for the final gloss. One Cut & Finish P6.02 (cut 6.0, gloss 8.0) corrects and seals in one step. We also stock Heavy Cut H8.02, Heavy Quick Cut B9.01, Micro Cut M2.02, Micro Cut & Finish P3.01 and the P1.03 and P2.03 finish polishes, plus Headlight Polish 1 and 2 for clouded lenses.

Gloss and protection. ProtectorWax, QF Quick Finish, Quick & Shine and Finish Spray Exterior keep the gloss up between details, and the Coating Towel 5 Pack wipes off residue.

Interior, plastics and glass. Pol Star cleans textiles, leather and Alcantara, COLOURLOCK Leather Care looks after leather, and Allround Surface Cleaner and MZR clean hard interior surfaces. Plast Star is a silicone-free plastic care, alongside Gummifix, Motorplast and Hydro Plast Care. Glas Star and Glass Cleaner Pro clean glass, and Fresh Up tackles odours.

Choosing a Koch-Chemie polish

Koch-Chemie rates its machine polishes for cut (how much they remove) and gloss (how much shine they leave), so you can pick the stage that matches the paint.

  • Heavy Cut H9.02 (cut 9.0, gloss 6.0) is the first stage on heavily weathered paint, deep scratches and sanding marks up to 1,200 grit. It suits soft and scratch-resistant paint. Koch-Chemie recommends a rotary polisher at medium speed and pressure, then a finishing stage with Micro Cut M3.02 or Micro Cut & Finish P3.01.
  • Fine Cut F6.01 (cut 6.0, gloss 7.0) is the middle stage for medium to heavily weathered paint and wash marks, at no more than 2,000rpm. Remove any streaks it leaves with Micro Cut M3.02.
  • Micro Cut M3.02 (cut 3.2, gloss 9.0) is the finishing polish. It removes holograms and fine scratches rather than filling them, which makes it the one to finish dark and sensitive colours.
  • One Cut & Finish P6.02 (cut 6.0, gloss 8.0) corrects and seals in one step, with carnauba wax, on a dual action polisher with at least a 15mm stroke: five pea-sized drops on the pad. Keep it off painted plastics and rubber.

Use a separate pad for each polish, keep off hot panels and store polishes away from frost and heat. For the pads and machines, see our polishing pads and polishing machines.
