From the manufacturer’s Safety Data Sheet, Section 8
“No H318 or H319 at SDS §2 mixture level. SDS §8 specifies goggles (DIN EN 166). Application to chrome wheels, bumpers, and trim at close range with paste on a cloth creates realistic drip and splash exposure. Tier reflects SDS §8 precautionary guidance and the close-range application scenario.”

From the manufacturer’s Safety Data Sheet, Section 8
“No H315 at SDS §2 mixture level. Petroleum-distillate carrier (isoalkanes + kerosine, 10·<15% each) is present in SDS §3 · per the chrome-polish rubric, a petroleum-distillate carrier is an independent basis for skin situational regardless of §2 H-code absence. SDS §8 specifies nitrile rubber gloves (EN 374, 0.5 mm). Tier reflects the carrier-based pathway and SDS §8 guidance.”

“No H335 or H331 at SDS §2 mixture level. Isoalkanes and kerosine (both petroleum-distillate carriers) appear in SDS §3 at 10·<15% each. Per the chrome-polish rubric mandatory carrier check, a petroleum-distillate carrier in §3 requires lungs: situational at minimum, independent of §2 H-code classification. SDS §8 states 'Not necessary if room is well-ventilated' · this is a specific ventilation-conditioned statement, not a blanket exemption. Tier is situational with enclosed_space trigger.”

TL;DR Simichrome is a concentrated paste that's a genuine category favorite · owners broadly confirm mirror-bright results on chrome, brass, stainless, and silver lasting 4·8 weeks. The SDS carries WARNING with H351 (suspected carcinogen) and a Prop 65 warning; petroleum-distillate carrier means lungs-situational PPE in enclosed spaces.
Apply a small amount to a cloth, work into the metal surface, buff off with a microfiber. The fine abrasive removes light oxidation, tarnish, and surface hazing in one or two passes · mirror-bright results are well-documented across chrome wheels, bumpers, exhaust, brass, and silverware. No polymer or protective-film chemistry; the 4·8 week durability reflects the polish result, not a coating. The product page and SDS provide no surface-compatibility guidance for painted panels, rubber, or plastic trim.
Anyone maintaining chrome wheels, bumpers, trim, exhaust, or household metal who wants a proven German-made formula. Skip it for deeply pitted chrome · a higher-cut metal polish is the right first step. Not the pick if confirmed paint-safe or plastic-trim-safe compatibility is required.
WARNING signal word, H351 (suspected carcinogen, Cat 2) from a trace ingredient at 0.1·<1%; Prop 65 warning from the same substance. SDS §8 specifies safety glasses and nitrile gloves. The petroleum-distillate carrier warrants lungs-situational precaution in enclosed spaces; outdoors or open-garage use is fine per SDS §8. Leave-on paste · do not allow to enter drains or water courses per SDS §12.
Neither the product page nor the SDS confirms compatibility with painted surfaces, rubber seals, or plastic trim. The product is marketed for chrome, aluminum, silver, brass, and stainless steel. The solvent carrier could affect some plastic trim or rubber seals with prolonged contact · apply to metal surfaces only and wipe off any product that contacts non-metal areas promptly.
The Prop 65 warning is attributable to diethanolamine amide (CAS 68603-42-9) at 0.1·<1% in the formula, which is listed as a California Prop 65 carcinogen. This is the same ingredient responsible for the H351 (suspected carcinogen, Cat 2) classification in the SDS. Prop 65 warnings are required when any listed ingredient is present above the no-significant-risk level · it signals the presence of a listed substance, not a specific exposure risk at normal use quantities.
The H351 (suspected carcinogen, Cat 2) classification applies to diethanolamine amide at 0.1·<1% of the formula. Cat 2 means 'suspected' based on limited evidence · not confirmed in humans. The classification drives the Prop 65 warning and the health score deduction, but it does not indicate an acute risk during normal occasional use. The strong owner reception reflects the product's performance, not its chemistry.
Simichrome contains no polymer, silicone, or ceramic protective layer chemistry · the formula is abrasive + solvent carrier. Community reviews on Amazon and motorcycle forums report the clean, bright finish holds for roughly 4·8 weeks under normal use before re-oxidation becomes visible. This is consistent with a well-polished bare-metal result rather than a protective film. For longer protection between polishings, a separate chrome sealant can be applied afterward.
Yes · the product page and manufacturer explicitly confirm use on chrome, aluminum, silver, brass, and stainless steel. It is widely used by motorcycle owners on chrome trim, aviation technicians on instrument housings, and jewelers on silverware. The very-fine aluminum-oxide abrasive is appropriate for all of these softer and harder metal surfaces.
