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.
GHS hazard codes are quoted from the manufacturer’s Safety Data Sheet. PPE tiers below translate those codes and the listed ingredient chemistry; they are not CarCareTruth recommendations.

From the manufacturer’s Safety Data Sheet, Section 8
“H319 (Eye Irritation Cat 2A · causes serious eye irritation) is the SDS §2 classification at concentrate strength. The product label retains CAUTION eye-irritant wording at use dilution, which is working-solution evidence that H319 survives to the wash scenario. Eye protection is warranted when handling or working with the solution.”

“SDS Section 11 notes CMIT/MIT (CAS 55965-84-9) may produce an allergic skin reaction. CMIT/MIT is a known contact sensitizer; once sensitization occurs, even trace exposure at working dilution can trigger a reaction. H317 skin-sensitizer logic applies, no dilution exception.”

TL;DR Adequate budget-tier cleaner that removes road film without stripping wax, with a Prop 65 warning from trace manufacturing impurities and a skin-sensitizer preservative (CMIT/MIT) that warrants attention for people with chemical sensitivities.
A cleaning formula that lifts dirt and road grime from painted surfaces at 1 oz per gallon in a two-bucket wash or per the foam cannon directions on the bottle label. Owners confirm it cleans routine contamination, produces adequate foam, and rinses away streak-free. The label claim that it won't strip wax is consistent with community expectations at the standard dilution. Performance lands at the category average, not above it.
Best for owners who want a dependable, widely available budget wash soap and aren't prioritizing foam volume or enthusiast-grade suds lubricity. The 64 oz concentrate with pack options makes it an economical choice for high-frequency washing. Skip it if you have a CMIT/MIT sensitivity or prefer to minimize Prop 65 exposure; for a cleaner with a stronger safety profile, look for a product carrying EPA Safer Choice certification.
The SDS signal word is WARNING. H319 (eye irritation, Category 2A) is classified at concentrate strength and the product label retains CAUTION eye-irritant wording at use dilution, confirming the classification survives to working concentration. The formula contains CMIT/MIT, a preservative biocide that SDS Section 11 identifies as a potential skin allergen; H317 skin-sensitizer chemistry applies without a dilution exception. SDS Section 15 lists multiple Prop 65 substances as nonfunctional constituents including 1,4-dioxane and formaldehyde. SDS Section 6 cites precautions against runoff reaching storm drains or waterways; ingredient-level data confirms aquatic toxicity for both primary surfactants.
The product label states 'Won't strip wax, like some dish soaps,' and the product listing feature bullet confirms it is safe for all automotive finishes including clear coats. The SDS does not disclose pH at working dilution, so pH confirmation is not available from the chemistry documentation. Community expectation at the 1:128 dilution ratio is that it does not strip paint protection, consistent with the label claim.
Yes. SDS Section 15 (revision 2026-02-06) explicitly lists multiple Prop 65-reportable substances as nonfunctional constituents of the formula · including 1,4-dioxane (cancer), formaldehyde (cancer), methanol (developmental), benzene, toluene, ethylbenzene, cumene, beta-Myrcene, and sulfur dioxide. The Amazon listing for this listing also confirms proposition_65_warning: true. Nonfunctional constituents are trace impurities from manufacturing processes; they do not serve a functional role in the formula. Their presence at SDS-disclosed levels triggers the Prop 65 warning label requirement.
CMIT/MIT (methylchloroisothiazolinone/methylisothiazolinone, CAS 55965-84-9) is a preservative biocide present at <1% per SDS Section 3. SDS Section 11 notes it may produce an allergic skin reaction. CMIT/MIT is a recognized contact sensitizer with a one-way sensitization mechanism: once an individual develops sensitivity, even trace exposures at working dilution can trigger a reaction. This is why skin protection is classified as recommended for this product even at normal wash concentration.
The label hand-wash directions specify 1 oz per gallon of water (1:128). For foam cannon use, the label includes separate cannon directions (the notes indicate this is also documented on the back panel). Scoring and health assessments for this review are based on the 1:128 two-bucket-wash dilution.
If Prop 65 exposure is a concern, the most reliable approach is to look for car wash products with EPA Safer Choice certification. EPA Safer Choice requires ingredient-level review and prohibits the use of substances of concern in listed concentrations. No specific branded alternative is named here because many popular shampoos in this category also carry Prop 65 notices from trace surfactant-process impurities.
