Prices may varyThe manufacturer's Safety Data Sheet classifies this product with one or more GHS Category 1 health hazards — the most severe tier. The hazard statements in quotes below are the verbatim GHS language from the SDS, as required by OSHA's Hazard Communication Standard. The line under each statement translates the GHS classification into plain language.
GHS Category 1 eye damage — classified as causing irreversible eye damage on contact.

From the manufacturer’s Safety Data Sheet, Section 8
“H318 (serious eye damage, Category 1) is classified in SDS §2 at concentrate strength · the GHS05 corrosion pictogram on the label reflects this classification. Eye protection is warranted when handling the undiluted concentrate.”

From the manufacturer’s Safety Data Sheet, Section 8
“H317 (skin sensitizer, Category 1) is on the SDS · present from fragrance and preservative ingredients (CMIT/MIT, Kathon CG). Skin sensitization is a one-way threshold: once sensitized, even trace exposures at working dilution can trigger a reaction. Gloves are warranted, particularly for anyone with prior sensitivity to isothiazolinone preservatives.”

TL;DR Brilliant Finish cleans road film reliably at 1 oz per gallon and the community confirms it does not strip wax, sealants, or ceramic coatings. The SDS carries H317 (skin sensitizer) and H318 (serious eye damage) at concentrate strength.
Brilliant Finish is a super-concentrated shampoo that lifts road film and brake dust while generating thick foam that lubricates the mitt through a full wash pass. Use 1 oz per gallon in a two-bucket setup or foam cannon. owner reviews from a large owner base confirm reliable cleaning, good mitt glide, and no wax or coating stripping at normal wash concentration.
Best for enthusiasts washing coated or waxed vehicles regularly · good foam volume and a proven coating-safe track record make it a solid weekly-wash choice for bucket, foam sprayer, or foam cannon. Skip it if you need a strip wash before reapplying wax or coating · use a dedicated strip shampoo for that step instead.
The SDS carries DANGER with H318 (serious eye damage, Category 1) at concentrate strength. H317 (skin sensitizer, Category 1) from isothiazolinone preservatives and fragrance carries no dilution exception · sensitization risk persists at any concentration for sensitized individuals. No Prop 65 warning. Both primary surfactants · sodium C10-16 alkylbenzenesulfonate and sodium lauryl sulfate · are flagged for aquatic toxicity in their ingredient profiles. SDS Section 12 provides no biodegradability data.
Griot's Garage markets Brilliant Finish as safe for waxes, sealants, ceramic coatings, and vinyl wraps · and owners are consistently positive on this point. The brand labels it as pH-balanced, though the SDS does not confirm pH at working-solution dilution. For maintenance washes on coated vehicles, the community consensus supports safe use. If you need a strip wash before reapplying protection, use a dedicated strip shampoo instead.
The label specifies 1 oz per gallon (1:128) for standard bucket use, which produces thick, rich lather per owner reviews. For foam cannon use, the product works at the same dilution in the cannon reservoir with water. Griot's markets it for bucket-and-mitt, foam sprayer, and foam cannon use.
No. The Rainforest API data for ASIN B00PA2LMVY shows no Prop 65 warning, and the SDS §15 makes no mention of California Proposition 65 substances.
The SDS carries a DANGER signal word with H317 (skin sensitizer Category 1) and H318 (serious eye damage Category 1) at concentrate strength. H318 drives the GHS05 (corrosion) pictogram. Both classifications apply to the undiluted concentrate · at 1:128 working-solution dilution the surfactant fraction is reduced significantly, but H317 sensitization risk does not fully resolve at dilution for sensitized individuals.
Like most car shampoos, the wash solution goes to driveway runoff and storm drains. The formula contains two surfactants · sodium C10-16 alkylbenzenesulfonate (LAS) and sodium lauryl sulfate · both flagged for aquatic toxicity in their ingredient profiles. The SDS Section 12 reports no mixture-level aquatic H-codes and no biodegradability data. The environment score of 5/10 reflects these ingredient-level concerns.
