This dedicated headlight polish strips UV-driven yellowing, oxidation layers and fine scratches off polycarbonate headlights — and brings back the original clarity and light transmission like a pro.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp\u003eYellowed and oxidised headlights are one of the most common cosmetic issues on cars five years and older: UV light slowly breaks down the outer protective layer of the polycarbonate headlights, the surface oxidises and yellows, and light transmission drops measurably. That doesn't just hurt the look of the car — it hurts road safety too, because clouded headlights cut the reach of the beam. The \u003cstrong\u003eSONAX PROFILINE HeadlightPolish\u003c\/strong\u003e is the pro headlight polish for mechanically reconditioning these headlight surfaces: abrasive enough to pull off yellowing and oxidation, fine enough to leave a clear, scratch-free finish.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStrips yellowing and UV oxidation off polycarbonate surfaces.\u003c\/strong\u003e Polycarbonate, the material modern car headlights are made of, is light and impact-resistant but UV-sensitive: without an intact UV protective layer the surface oxidises into a yellowy, cloudy, matte film that scatters light instead of letting it through. The HeadlightPolish pulls that oxidation layer off with fine abrasive polishing and exposes the clear polycarbonate underneath — the result is a headlight that looks and works like new.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFine abrasion for clear, transparent results without scratches.\u003c\/strong\u003e Polycarbonate headlights are softer than car paint and react to overly coarse abrasion with new scratches that hurt clarity just as much. The HeadlightPolish is dialled in for the specific demands of headlight reconditioning: fine abrasive particles that take off the yellowing and light scratches without cutting new, deep marks that you'd have to polish out again.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorks by hand or by machine.\u003c\/strong\u003e The HeadlightPolish formula is built to run both on a polisher (dual-action or rotary with a small pad) and by hand with an applicator. By hand you can work small headlights, headlights with tricky geometry and on-the-spot touch-ups well — for bigger or heavily oxidised headlights the machine is more efficient and gives a more even result.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e On heavily yellowed headlights a multi-step job is the way to go: first wet-sand the worst of the oxidised crud with fine sandpaper (P1000–P2000) to take the oxidised layer off evenly, then polish it out with the HeadlightPolish to remove the sanding marks and bring up the gloss. For that full process the \u003ca href=\"\/en\/products\/sonax-profiline-scheinwerferaufbereitungsset-aufbereitungsset\"\u003eSONAX PROFILINE Headlight Reconditioning Set\u003c\/a\u003e is the way to go — it packs all the materials you need including the sandpapers. After polishing, always lay down a UV protective sealant — without protection the headlights yellow again within 6–18 months. The \u003ca href=\"\/en\/products\/sonax-profiline-ceramiccoating-cc-headlightcoating-scheinwerferversiegelung\"\u003eSONAX PROFILINE HeadlightCoating \"CC\"\u003c\/a\u003e is the ceramic sealant for lasting UV protection after the polish.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003ePolycarbonate chemistry — how the HeadlightPolish removes headlight yellowing\u003c\/h3\u003e\n\u003cp\u003eThe way the \u003cstrong\u003eSONAX PROFILINE HeadlightPolish\u003c\/strong\u003e works comes down to mechanical micro-abrasion that takes the oxidised, yellowed polycarbonate surface off layer by layer. Chemically, the oxidation layer on yellowed headlights is a photodegradation layer — UV light breaks the polymer chain bonds in the polycarbonate and forms carbonyl groups, which cause the yellow discolouration. That layer sits on the top micrometres of the polycarbonate and can be cut off by abrasion without touching the material underneath.\u003c\/p\u003e\n\u003cp\u003eThe abrasive particles in the HeadlightPolish are tuned for polycarbonate surfaces: polycarbonate is noticeably softer than tempered glass or car paint and reacts faster to abrasion. Particles that are too coarse would cut deep marks into the clear material that hurt light transmission just as much as the original yellowing. The HeadlightPolish uses finely ground abrasive particles that take the layer off in a controlled way and leave a polished, clear surface. The result depends on how far the yellowing and oxidation have gone: lightly yellowed headlights come fully clear with a single polish, heavily yellowed or deeply eroded headlights need several passes or a wet-sanding step first.\u003c\/p\u003e\n\u003cp\u003eAn important point in headlight reconditioning is understanding the layer structure: new headlights have a factory-applied UV protective layer (hardcoating) that shields the polycarbonate from UV light. Over time that protective layer breaks down, and the unprotected polycarbonate starts to oxidise. The HeadlightPolish removes the oxidation layer, but not the underlying problem: the freshly polished polycarbonate has no UV protection after the polish, and without a new protective layer it will yellow again. That's why the combo of HeadlightPolish (the polish) and a UV-resistant sealant is the complete reconditioning concept for headlights that stay clear.\u003c\/p\u003e\n\u003cp\u003eThe clarity and light transmission of a freshly reconditioned headlight can make the difference in TÜV-relevant terms: headlights that have lost more than 50% of their light transmission to extreme yellowing can be flagged as defects at a roadworthiness inspection. A professional headlight reconditioning doesn't just bring back the look — it also has practical relevance for vehicle safety and registration.\u003c\/p\u003e\n\n\u003ch3\u003eUsing the HeadlightPolish right — hand polishing and machine work\u003c\/h3\u003e\n\u003cp\u003eApplying the headlight polish starts with prep: wash and dry the headlight thoroughly to get rid of grit and coarse dirt particles that would scratch during polishing. Mask off the adjacent paint with painter's tape, since the HeadlightPolish abrades clear coat too — and that's a pain to fix afterwards. Check the headlight for scratches and how deep any cracks run: surface scratches polish out, but deep cracks or internal headlight damage can't be fixed by polishing.\u003c\/p\u003e\n\u003cp\u003eBy hand: lay the HeadlightPolish onto an applicator or a soft microfibre cloth. Work even circular motions with medium pressure across the whole headlight face — dwell time matters less here than the mechanical action from pressure and movement. By hand you'll need several passes to get the same result you'd get from one machine pass. The hand method works especially well on smaller headlights or for spot work (single blemishes or local oxidation patches) where a machine is less precise.\u003c\/p\u003e\n\u003cp\u003eBy machine: run a small pad (65–80 mm) on a dual-action or rotary polisher (speed 3–4) with even, light pressure across the headlight face. The curved geometry of most headlights calls for a flexible pad that follows the shape, and controlled pad guidance to avoid uneven edge pressure. After the machine pass, buff off with a clean microfibre cloth and check the result in raking light for any leftover sanding marks or haze. Do a second pass if needed, especially on heavily yellowed headlights.\u003c\/p\u003e\n\n\u003ch3\u003eWhere the HeadlightPolish earns its keep — when headlight reconditioning makes sense\u003c\/h3\u003e\n\u003cp\u003eA professional headlight reconditioning with the \u003cstrong\u003eSONAX PROFILINE HeadlightPolish\u003c\/strong\u003e pays off in plenty of situations. The most common case is sprucing up the look of cars five years and older that have lost their appeal to UV yellowing. In the used-car trade, headlight reconditioning is one of the most cost-effective upgrades going: a professional job takes 20–30 minutes per car, uses little material and lifts the look of the car a lot — an effort that pays for itself fast in the asking price.\u003c\/p\u003e\n\u003cp\u003eAs part of a full detail, headlight reconditioning is a quality signal: a car with clear, freshly reconditioned headlights next to high-gloss paint reads as overall coherence and craftsmanship. Plenty of customers value it when a detailer looks after this detail too, and take it as a marker for the quality of the whole job. Offering headlight reconditioning as an add-on service is, for that reason, a worthwhile addition to a detailer's line-up.\u003c\/p\u003e\n\u003cp\u003eOn fleet and commercial vehicles, headlight reconditioning matters for safety: van fleets that run a lot at night or in poor visibility benefit from maximum headlight brightness. Regular headlight care as part of a fleet maintenance plan extends the service life of the headlights and pushes back the point where a costly headlight replacement becomes necessary.\u003c\/p\u003e\n\n\u003ch3\u003eThe HeadlightPolish in the product system — polish, sealant and reconditioning set\u003c\/h3\u003e\n\u003cp\u003eWithin the SONAX PROFILINE headlight care range, several products work together into a complete reconditioning concept. The HeadlightPolish handles the mechanical correction work — it pulls off the oxidation layer and brings the headlight up to high-gloss transparency. After polishing, a protective sealant is a must to lock the result in for the long haul. The \u003ca href=\"\/en\/products\/sonax-profiline-ceramiccoating-cc-headlightcoating-scheinwerferversiegelung\"\u003eSONAX PROFILINE HeadlightCoating \"CC\"\u003c\/a\u003e is the ceramic UV protective sealant that shields the freshly polished polycarbonate from renewed UV degradation and stretches the durability of the result out to several years.\u003c\/p\u003e\n\u003cp\u003eFor shops that want to offer headlight reconditioning as a full service, the \u003ca href=\"\/en\/products\/sonax-profiline-scheinwerferaufbereitungsset-aufbereitungsset\"\u003eSONAX PROFILINE Headlight Reconditioning Set\u003c\/a\u003e is a handy all-in-one: it holds all the materials for the full process — sandpapers for the pre-step on heavily yellowed headlights, the HeadlightPolish for the polishing phase, and the HeadlightCoating for the final UV protection. For shops bringing this service in fresh, the set shortens the learning curve and takes the guesswork out of picking materials.\u003c\/p\u003e\n\u003cp\u003eCompared with third-party headlight cleaning products, the SONAX PROFILINE HeadlightPolish brings the advantage of a matched product system: the polish formula is built so that the polycarbonate ends up with an optimal surface for the HeadlightCoating after reconditioning — no residue, no incompatibility with the sealant polymer. In-system compatibility matters especially with headlights, since poor or insufficient bonding of the protective layer leads to quick flaking and so to a short-term win with no lasting effect.\u003c\/p\u003e\n\n\u003ch3\u003eBuy the SONAX PROFILINE HeadlightPolish — sizes and recommendation\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eSONAX PROFILINE HeadlightPolish\u003c\/strong\u003e comes in 250 ml as well as a 2-pack and a 3-pack. The 250 ml size is the right one for one-off and occasional users: a pair of headlights typically takes 10–20 ml, so the 250 ml bottle is good for 12–25 full headlight jobs. For detailing shops running several cars a week, the 3-pack is the most economical option and keeps you stocked for longer without frequent reorders.\u003c\/p\u003e\n\u003cp\u003eThe HeadlightPolish is well worth keeping as a fixed part of the service line-up for any shop that offers detailing across the board. Headlight reconditioning is a service plenty of customers actively ask for, and one that delivers a measurable value bump to the car — both in looks and in function. The combo of HeadlightPolish and HeadlightCoating as a complete headlight service is an attractive add-on that lifts the margin per detail without much extra work.\u003c\/p\u003e\n\u003cp\u003eBottom line: the SONAX PROFILINE HeadlightPolish is the right product for anyone who wants to recondition yellowed and oxidised headlights like a pro. This professional headlight polish from the PROFILINE range is dialled in for polycarbonate surfaces, delivers clear and transparent results, and is the first step of a complete headlight reconditioning process that's finished off with the HeadlightCoating.\u003c\/p\u003e","brand":"SONAX","offers":[{"title":"250ml","offer_id":53521230889295,"sku":"D1-SNX-2761410","price":21.0,"currency_code":"USD","in_stock":true},{"title":"2x 250ml Set","offer_id":53521230922063,"sku":"D1-SNX-2761410_2","price":41.0,"currency_code":"USD","in_stock":true},{"title":"3x 250ml Set","offer_id":53521230954831,"sku":"D1-SNX-2761410_3","price":61.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/sonax-profiline-headlightpolish-scheinwerferpolitur_250ml.png?v=1730655082","url":"https:\/\/detailing1depot.com\/en\/products\/sonax-profiline-headlightpolish-scheinwerferpolitur","provider":"Detailing1","version":"1.0","type":"link"}
