Best Metal Polishes for Cars: Chrome, Exhaust & Alloy Compared (2026)
The best metal polish depends on the metal and how oxidised it is. For stubborn exhaust-tip carbon, a paste like Carbon Collective Lustre cuts hardest; for dull trim and alloys, a one-step liquid such as Chemical Guys Heavy Metal Polish restores and seals; on delicate show chrome, start with the gentlest light polish and test a hidden spot first.

Top picks
- Carbon Collective Lustre Metal Polish Paste — a paste with higher cut than its liquid version, using diminishing micro-abrasives to remove oxidation and carbon build-up; safe on aluminium, stainless, magnesium, copper and brass. Best for stubborn exhaust tips.
- Supernatural Medium Cut Metal Polish — a medium-to-heavy cut for corroded or tarnished solid metal, used as stage 1 before finer grades. Not for thin plating or anodised surfaces.
- Supernatural Ultra-Fine Metal Polish — the finest grade in the range, for a true mirror finish as the final stage after medium and fine polishing on uncoated, unplated solid metal.
- Chemical Guys Heavy Metal Polish — revives dull, oxidised metal to a mirror finish in one step and leaves a polymer sealant that slows re-oxidation; works on steel, brass, chrome and aluminium.
- Chemical Guys Light Metal Polish — a gentle one-step clean-polish-protect for light stains and oxidation on chrome, stainless and aluminium; the safer starting point for delicate show chrome.
- GTECHNIQ M1 All Metal Polish (pH 8) — a fine, quick-working all-rounder that leaves a crystal-clear finish with no burning or marring across a wide range of metals.
- Griot's Garage Ceramic Metal Polish — sub-micron abrasives remove oxidation while SiO2 and silane polymers add hydrophobic protection, so you polish and protect alloys, chrome and stainless in one pass.
How to choose
Match the cut to the metal and its condition. Chrome is the most delicate — scratches can't be levelled out like paint, so start with the gentlest light or fine polish and test a hidden spot first. Stainless and aluminium tolerate more cut, so work with the grain and step down from a medium cut to a fine then ultra-fine polish for a mirror finish. Pastes generally cut harder and suit heavy oxidation and exhaust carbon; liquids and creams spread more easily and are kinder on delicate or small areas. Avoid anodised or thin-plated trim with products that warn against it (Koch Chemie's Metal Polish and the Supernatural range both do). Always degrease and clean the metal first, then buff off residue with a clean microfiber.
FAQ
Can you use metal polish on chrome?
Yes, but chrome is the most delicate finish and its scratches can't be polished out like paint. Start with the gentlest light or fine polish, test a hidden area first, and never use an aggressive cut on thin show chrome.
What is the best metal polish for exhaust tips?
Stainless and aluminium tips tolerate more cut, so a paste like Carbon Collective Lustre or a medium-cut liquid lifts carbon build-up and oxidation. Finish with a fine or ultra-fine polish for a mirror shine, always working with the grain.
Is metal polish safe on aluminium and anodised trim?
Most polishes suit bare aluminium, but anodised or thin-plated surfaces are an exception — Koch Chemie Metal Polish and the Supernatural range specifically warn against anodised or plated parts. Check the label before polishing coated trim.
