SONAX PROFILINE MetalPolish Metal Polish (Medium-Cut) 250ml

Bring tarnished metal surfaces to a high shine — with SONAX PROFILINE MetalPolish

What does SONAX PROFILINE MetalPolish do? The metal polish with medium abrasive power removes tarnish, oxidation, light rust, and dullness from aluminum, brass, chrome, and stainless steel — bringing metal surfaces to a mirror-like high shine.

Polished metal surfaces lose their luster over time — oxygen, moisture, UV light, and environmental acids leave tarnish, oxidation layers, and a characteristic dullness that simple cleaning cannot remove. This is where SONAX PROFILINE MetalPolish comes in: a high-gloss polish with a medium abrasive grade that, based on high-quality abrasive minerals, gently removes tarnish and oxidation layers, revealing a highly mirror-polished surface beneath. The formula is suitable for all common metals — aluminum, brass, chrome, stainless steel — and works without aggressive acids or alkalis that can cause corrosion damage on sensitive metal surfaces.

• Medium abrasive power for a wide range of applications. The medium cut allows for quick polishing even on heavily tarnished or dull metal surfaces, without excessive material removal or damaging more sensitive surfaces. For most applications — exhaust tips, aluminum wheel well polishing frames, chrome attachments, stainless steel cladding — the medium abrasive power is the right starting point, delivering visible results without unnecessarily removing material.
• Use on all common metal surfaces. Aluminum, brass, chrome, stainless steel, copper — the polish works on all these materials without specific compatibility issues. It has proven particularly effective on motorcycle parts, exhaust systems, wheels, boat fittings, and kitchen objects made of polished metal, where both cleaning action and high-gloss results are desired.
• High-gloss finish directly from the tube. After polishing, a mirror-like high-gloss finish is created that requires no separate post-treatment. This saves a step compared to two-stage systems, where coarse and then pure finisher work is required — with PROFILINE MetalPolish, the abrasive and polishing phases are combined in one step.

Detailing1 Pro Tip: For optimal results, thoroughly clean and dry the metal surface before polishing — dirt particles on the surface cause deeper scratches during polishing than the abrasive in the polish itself. Apply the MetalPolish to a clean, soft cotton cloth or polishing pad and work in circular, overlapping motions in small areas. Do not apply too thinly — the paste should remain visibly on the surface until it hardens and becomes slightly cloudy. Then polish with a clean cloth and check the result. A second pass may be necessary for heavily tarnished areas.

Metal polish with medium abrasive power — how the medium cut works

The action of a metal polish is based on controlled micro-abrasive processes: fine abrasive grains in the polishing paste remove the uppermost layer of oxidation, tarnish, and micro-scratches, while simultaneously smoothing the underlying metal surface. The finer the grit, the higher the achievable shine, but the longer the working time for heavily damaged surfaces. The medium abrasive power of SONAX PROFILINE MetalPolish is a conscious compromise: strong enough to remove even significant tarnish and medium oxidation layers in one step, fine enough to produce a high-gloss finish directly, without the need for a separate finishing step.

The abrasive minerals in the formula are selected to work gently on metal surfaces and not cause excessive material removal. This is particularly important for thinly plated chrome or coated aluminum: overly aggressive abrasives can penetrate protective layers and expose the underlying base material, accelerating corrosion. The medium abrasion of MetalPolish keeps this risk at a controlled level and is matched to the typical thickness of chrome and aluminum coatings.

A conceptual difference to paint polishes such as SONAX PROFILINE PerfectFinish is important: paint polishes are formulated for organic polymer layers (clear coat), while metal polishes are for inorganic metal surfaces. The abrasive grains are chosen differently, and the carrier paste is adapted to the specific adhesion and heat conduction of metal. These products are not interchangeable — a paint polish on metal will not produce optimal results, and a metal polish on clear coat can cause scratches depending on the abrasive hardness. Therefore, use MetalPolish exclusively on bare, non-painted metal surfaces.

After polishing — when the applied product has become cloudy and has been polished off with a cloth — MetalPolish leaves no bothersome oil film or residue. The metal remains fresh, shiny, and grippy after polishing. Optional post-sealing with a metal protection product or wax film can extend the re-tarnish period and is particularly recommended for chrome attachments in outdoor areas.

Applying metal polish correctly — step-by-step for maximum shine

The application of SONAX PROFILINE MetalPolish works both by hand and with a rotating machine. By hand: Apply a hazelnut-sized amount of polish to a clean cotton cloth, a polishing cloth, or a soft polishing block. Spread over the metal surface with circular or linear movements — not too fast, but with even pressure in small sections of approx. 20×20 cm. Allow the polish to dry slightly and appear milky-cloudy (typically 30–60 seconds at room temperature), then polish with a clean, dry cotton cloth. The result is immediately visible: the cloudy residues contain the dissolved oxide and removed dirt.

With a machine (rotary or orbital polisher): Choose a suitable pad depending on the machine — a medium-hard polishing pad or a cotton polishing pad is recommended for MetalPolish. Select a low speed (rotary: approx. 1000–1500 rpm, orbital: level 3–4), move evenly over the surface. Machine polishing on metal saves considerable time and produces more even results than hand polishing due to the mechanical pressure, but requires a little more practice to avoid overheating on edges and corners. After machine polishing, polish off as with hand application.

A second pass may be necessary on heavily tarnished or deeply oxidized surfaces. Important: After each pass, check with a clean cloth whether the desired result has been achieved before applying further polishing passes — excessive polishing unnecessarily removes material without further improving the result.

Metal polish application areas — where MetalPolish works best

MetalPolish shows its strength wherever polished metal surfaces have become dull and unsightly due to environmental influences. In the automotive sector: chrome attachments, aluminum wheel rims, stainless steel sills, exhaust tips and systems (always apply to cold parts!), motorcycle exhaust manifolds, aluminum engine covers, and motorsport applications made of polished aluminum or titanium. The results are particularly noticeable on exhaust systems that develop typical tarnish colors due to heat — blue, golden brown, purple. These can often be completely or largely removed with a metal polish, restoring the exhaust to its original metal finish. For titanium components (racing, high-performance exhaust), the tarnish colors are often considered an aesthetic feature — here, before polishing, it should be considered whether the original finish is actually desired or whether the tarnish colors should deliberately be preserved.

When it comes to aluminum wheels, an important distinction must be made: bare, uncoated aluminum wheels (rare, but common in vintage car and motorsport sectors) can be treated directly with metal polish. Standard new and used car wheels, however, are covered with a clear coat or anodized — these should not be treated with metal polish, as the abrasion attacks the clear coat. The correct approach for painted wheels is a paint polish, not a metal polish. If in doubt: Test a tiny area in an inconspicuous spot before treating the entire rim.

Outside the automotive sector, MetalPolish is equally powerful: boat fittings and propellers made of brass or stainless steel, stainless steel railings and handrails, polished brass fittings, historical objects made of silver or bronze, kitchen objects made of polished stainless steel. The polish has limitations on painted or anodized metal surfaces — these protective layers should not be mechanically polished. Anodized aluminum wheels or powder-coated components are therefore not suitable application areas for metal polish, regardless of the product used.

Metal polish comparison — PROFILINE MetalPolish vs. XTREME MetalPolish and alternatives

The SONAX range includes two metal polishes: the PROFILINE version and SONAX XTREME MetalPolish. Both remove tarnish and oxidation on metal surfaces, but differ in package size and positioning. XTREME MetalPolish (150 ml tube) is aimed at hobby detailers and occasional users who prefer a handy package size for smaller jobs and individual applications. PROFILINE MetalPolish (250 ml) is designed for regular users and businesses who polish more frequently and want to keep a slightly larger quantity in stock.

In terms of content, both products use comparable abrasive minerals for the medium cut — the main difference lies less in the mode of action than in product size and positioning: PROFILINE is the professional line for regular use, XTREME is the consumer pack for home use. Those who work in a business or regularly detail motorcycles, vehicles, or boats will opt for PROFILINE; those who occasionally polish the wheels or exhaust of their vehicle are equally well advised with XTREME MetalPolish.

For special applications, it is worth looking at other products in the SONAX PROFILINE range: SONAX PROFILINE GlassPolish specializes in glass surfaces — scratches and water spots on windshields or rear windows — and works with cerium oxide abrasive technology on a different material class than MetalPolish. Those who are putting together a comprehensive vehicle detailing kit that covers both paint and metal work will find the right special polish for every material in the SONAX PROFILINE range.

Buying SONAX PROFILINE MetalPolish — Recommendation and Target Group

SONAX PROFILINE MetalPolish is the choice for anyone who regularly polishes metal surfaces and wants to use a reliable, proven professional product. The 250 ml tube is sufficient for many applications — a single exhaust system, a complete motorcycle, several chrome attachments — and offers maximum flexibility thanks to its medium abrasive power: from occasional exhaust refresh to systematic detailing of an entire vehicle.

In addition to the polish, a set of high-quality cotton cloths or polishing applicators is recommended for even results when polishing by hand. Important: Do not use microfiber cloths for polishing on brightly polished metal surfaces — microfiber loops can leave fine scratches on high-gloss metal that do not occur with cotton cloths. For machine polishing, cotton polishing pads or medium-soft foam polishing pads are suitable.

If you want a long-lasting protective layer after polishing that significantly delays re-tarnishing, you should plan a metal sealing step after using MetalPolish: a thin wax film, a metal protection oil, or in some cases a ceramic sealant can extend the durability of the polished condition from a few weeks to several months, especially on exterior attachments exposed to weather. This is particularly worthwhile for elaborately prepared exhaust systems or motorcycle chrome parts where the result should last as long as possible. For hobby detailers who occasionally polish individual metal parts, the PROFILINE MetalPolish in the 250 ml tube is sufficient for many years — the tube is economical and the product has unlimited shelf life with correct storage (cool, dry, sealed).
