The 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.
If splashed in eyes:
Call Poison Control immediately at 1-800-222-1222 (US, 24/7, free) and have the product container with you. Poison Control's standing guidance is to not induce vomiting after chemical exposure; they will direct first-aid steps based on the specific product.
About this product's hazards. This product's Safety Data Sheet uses signal word DANGER.Read the manufacturer's SDS and follow all safety instructions before use.

Health score is for adult use as intended, per the manufacturer's SDS. It does not model child ingestion, accidental spill cleanup, or off-label use. See the safety panel below for full hazard classification, and /disclaimer for the full editorial scope.

Especially relevant: handling concentrate
Translated from the manufacturer’s Safety Data Sheet, Section 2
H318 (serious eye damage, Category 1) is classified in SDS Section 2 at the mixture level, which requires the required tier regardless of working-solution dilution. The GHS05 corrosion pictogram reflects this classification. At the label's 1 oz per gallon working dilution the surfactant load drops to roughly 0.03 percent, which is why the health deduction for this code is calibrated to zero even though the PPE tier itself does not get a dilution exception.
U.S. regulatory standard
29 CFR 1910.133(a)(1); 1910.151(c)
“The employer shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards from… liquid chemicals, acids or caustic liquids…”
ANSI Z87.1 (chemical splash protection — incorporated via §1910.6)

Translated from the manufacturer’s Safety Data Sheet, Section 2
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.
U.S. regulatory standard
29 CFR 1910.138(a); 1910.132(d)
“appropriate hand protection when employees' hands are exposed to hazards such as those from skin absorption of harmful substances.”

Only when: handling concentrate · in enclosed space
Translated from the manufacturer’s Safety Data Sheet, Section 8
SDS Section 8 states respiratory protection is 'not typically required' for this product. Section 2 carries no inhalation-hazard GHS code (no H330, H331, H334, or H335), consistent with a water-based, non-aerosolized wash concentrate. Provide ventilation when mixing or pouring the concentrate, or when washing in an enclosed garage without airflow.

No PPE specified in published sources for ventilation. Absence does not imply “not needed” — consult the full Safety Data Sheet.

Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.

TL;DR The SDS carries a DANGER signal word from a Category 1 skin sensitizer and a Category 1 serious-eye-damage classification, placing Brilliant Finish in CCT's Serious Hazard band and requiring eye protection whenever you handle the bottle. Cleaning performance is otherwise solid: it lifts road film reliably at 1 oz per gallon, and owners say it does not strip wax, sealants, or ceramic coatings.
Brilliant Finish is a concentrated shampoo that lifts road film and brake dust while building thick foam that lubricates the mitt through a full wash pass. Use 1 oz per gallon in a two-bucket setup or foam cannon. A large base of owners report 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 use. 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 a DANGER signal word driven by two Category 1 mixture classifications: H318 (serious eye damage) and H317 (skin sensitizer). That puts this product in CCT's Serious Hazard band and requires eye protection whenever handling the bottle, not just the concentrate; the surfactant load behind H318 does drop to roughly 0.03 percent at the 1 oz per gallon working dilution, but the mixture-level classification still governs the rating. H317 sensitization has no dilution exception, so gloves are warranted, particularly for anyone sensitive to isothiazolinone preservatives. No Prop 65 warning. Both primary surfactants, sodium C10-16 alkylbenzenesulfonate and sodium lauryl sulfate, are flagged for aquatic toxicity, and SDS Section 12 reports 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 product listing 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 the mixture level. H318 drives the GHS05 (corrosion) pictogram. A Category 1 mixture classification puts this product in CCT's Serious Hazard health band and forces eye protection to the required tier, even though the surfactant load driving H318 drops to roughly 0.03 percent at the 1:128 working dilution. H317 sensitization risk does not fully resolve at dilution for sensitized individuals, so gloves remain recommended.
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.
