Mothers California Gold Chrome Polish

The SDS does not specifically address painted surfaces, rubber seals, or plastic trim compatibility. The product is marketed exclusively for chrome. The glycol ether co-solvents at 1–5% each are unlikely to damage cured OEM clear coat during brief contact, but the product page makes no paint-safe claim. If you're polishing chrome trim adjacent to painted panels, apply carefully and wipe off any product that lands on painted areas promptly.

The SDS is from 2015 and predates the Prop 65 listing of isopropyl alcohol (CAS 67-63-0), which is present in the formula at 1–5%. California's Prop 65 list has expanded substantially since 2015 — the Amazon listing reflects the current compliance obligation, and the Prop 65 warning is the accurate current status.

Mothers markets this as a 2-in-1 that cleans and protects in one step via advanced polymers. Amazon reviews with time-stamped follow-up suggest protection against re-tarnishing lasts approximately 4–6 weeks under regular washing conditions — shorter in wet-climate or salt-road environments. For wheels exposed to brake dust and harsh washing, re-application monthly or after every few washes is common practice.

Community reviewers consistently use Mothers Chrome Polish on polished aluminum, stainless steel, and chrome-plated wheels with good results — the mild fine-mineral abrasive works on any bright metal surface. It is not formulated for matte or brushed finishes; the abrasive component will alter those surface textures.

A clean microfiber towel is the community-standard choice — it buffs off the residue without scratching the polished surface. Cotton terry or paper towels are documented to leave fine scratches on chrome, particularly on polished aluminum wheels. The product is liquid, not a dry chalk-style paste, so it buffs off easily without much arm effort once applied in a thin layer.
