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 skin corrosion — classified as causing irreversible skin damage on contact.
GHS Category 1 eye damage — classified as causing irreversible eye damage on contact.
If on skin or 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.

Translated from the manufacturer’s Safety Data Sheet, Section 2
SDS Section 2 classifies the concentrate as Eye Dam. 1 (H318, serious eye damage) and Skin Corr. 1 (H314, whose hazard statement also covers severe eye damage). The concentrate pH of 12.6 is above the 12.5 caustic threshold, which independently forces eye protection at concentrate strength regardless of the working-solution dilution math.
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)
OSHA standards apply to workplaces. Cited here as the U.S. reference threshold for the underlying hazard class.

Translated from the manufacturer’s Safety Data Sheet, Section 2
SDS Section 2 classifies the concentrate as Skin Corr. 1 (H314, severe skin burns), driven by the NaOH/KOH alkaline system at 2.5-10% combined. The concentrate pH of 12.6 is above the 12.5 caustic threshold, so skin protection is required when handling the undiluted product.
U.S. regulatory standard
29 CFR 1910.132; 1910.133; 1910.138; 1910.151(c)
“Where the eyes or body of any person may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing of the eyes and body shall be provided within the work area for immediate emergency use.”

Translated from the manufacturer’s Safety Data Sheet, Section 8
SDS Section 8 calls for respiratory protection if the airborne concentration cannot be kept below exposure limits. Section 11 goes further, stating prolonged inhalation of the product is corrosive to mucous membranes and the upper respiratory tract, which is a real finding rather than pure boilerplate. Section 2 carries no H330, H331, or H334 code, so this stops short of a required tier.

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 Strongly alkaline concentrate: a DANGER signal word, H314 skin corrosion and H318 serious eye damage codes, and a concentrate pH of 12.6 that requires eye and skin protection undiluted. That chemistry resolves at the standard 1:512 wash dilution, where it cleans well with heavy suds. A Prop 65 warning applies, and both Amazon ASINs are currently unavailable.
Citrus Wash Clear cleans by lifting dirt off the surface; use 1/2 oz per two gallons for a standard wash in a bucket, foam gun, or foam lance. Owners confirm reliable road film removal and frothy suds at that ratio. At 1:512 dilution it does not strip wax or sealant; the label also specifies a paintwork-cleanser mode at 2 oz per gallon, and owners document that intentional strip-wash use case.
Best fit is someone who wants one concentrate for both maintenance washes and occasional strip washes; the same jug handles both at different dilutions, and the working solution is not corrosive. Skip it if you would rather avoid a caustic concentrate, or if Prop 65 is a concern. HydroSuds suits routine coated-car maintenance better.
H314 (skin corrosion) and H318 (serious eye damage), both Category 1, are classified at concentrate strength; the NaOH/KOH alkaline system drives both, and the concentrate pH of 12.6 requires eye and skin protection undiluted. Both codes resolve at 1:512 dilution. SDS Section 15 lists 1,4-dioxane (cancer) and sulphur dioxide (reproductive harm), Prop 65 substances. The LAS surfactant carries an ingredient-level aquatic toxicity rating, reflected in the environment score of 6/10.
It depends on dilution. At the standard label dilution (1/2 oz per two gallons), the formula is likely wax-safe; owners confirm this as a maintenance wash that does not strip protection at normal concentration. At the paintwork-cleanser dilution (2 oz per gallon, an 8x more concentrated solution), the brand explicitly markets it as a cleanser that strips contamination, and several owners confirm intentional strip-wash use at that ratio. For coated vehicles, use the standard 1:512 dilution only.
Yes. SDS Section 15 (CWS301 proxy SDS, same formula) lists 1,4-dioxane (cancer) and sulphur dioxide (reproductive harm) as Prop 65 substances. The product listing returns a negative flag for both ASINs, but those listings are currently out of stock and may not reflect current Prop 65 labeling. SDS Section 15 is the authoritative source.
The DANGER classification and the required eye and skin protection come from the alkaline ingredient system. The SDS lists NaOH (sodium hydroxide) at 2.5-10% concentrate, which drives a concentrate pH of 12.6 and triggers H314 (skin corrosion) and H318 (serious eye damage). Because that pH sits above the 12.5 caustic threshold, eye and skin protection are required whenever the concentrate is handled directly, such as during measuring or mixing. At the standard working dilution of 1/2 oz per two gallons (a 1:512 dilution), both H-codes resolve and the pH drops well below the corrosion threshold, so the wash solution itself is not corrosive.
It is among the most concentrated in the Chemical Guys lineup at 1/2 oz per two gallons (1:512 dilution) for a standard maintenance wash. The label also specifies a paintwork-cleanser mode at 2 oz per gallon, eight times stronger. By comparison, HydroSuds is used at 1-3 oz per gallon (1:43 to 1:128 range). Citrus Wash Clear's higher dilution ratio means a one-gallon jug goes significantly further, though both Amazon ASINs are currently unavailable.
