Only when: when spraying
Beyond SDS: translated from the ingredient chemistry
Cleaner SDS §2 is GHS Not Classified · no H319 or H318. Pump-spray application during close-range brush agitation creates plausible mist-contact risk, but the chemistry (water-based, pH 7-8, no irritant ingredients above OSHA HazCom thresholds) does not support a recommended-tier eye-protection call.
CarCareTruth publishes the cited sources verbatim and does not advise what action a user should take. Consult the full SDS before use.
Only when: prolonged use
Beyond SDS: translated from the ingredient chemistry
Cleaner SDS §2 has no H315 or H317. Brush agitation with hands in direct contact with the wet cleaner during a 15-30 minute session is the primary plausible skin-contact pathway, but the chemistry is benign at consumer concentration.
CarCareTruth publishes the cited sources verbatim and does not advise what action a user should take. Consult the full SDS before use.
Only when: in enclosed space · prolonged use
Translated from the manufacturer’s Safety Data Sheet, Section 8
Cleaner SDS §8 names respiratory equipment only for insufficient ventilation, standard boilerplate rather than a specific-use trigger, and §2 carries no inhalation H-code. Applying this outdoors or in an open garage bay isn't a respiratory exposure pathway, but the situational tier covers washing in an enclosed, poorly ventilated space for a prolonged session.

California Prop 65 warning
This product's Amazon listing carries a California Prop 65 warning. The manufacturer's Safety Data Sheet (§15) does not list a Prop 65 substance for this product — we show the warning for transparency and flag the discrepancy rather than silently picking a side.
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.
No warranties. CarCareTruth makes no warranties, express or implied, and expressly disclaims the implied warranties of merchantability and fitness for a particular purpose.

TL;DR A two-bottle kit pairing a mild surfactant cleaner with 303 Fabric Guard for upkeep on acrylic-canvas tops. The cleaner removes road grime and light staining but has no mildewcide, so established black mold needs a dedicated remover first. The cleaner itself has no signal word; the DANGER and Prop 65 warnings on the kit box come from the Fabric Guard bottle.
Spray onto a damp top, agitate with a soft brush, rinse with a hose. Community reports on r/AutoDetailing support reliable removal of grime and light staining on black and tan acrylic canvas with no color shift over multiple seasons. Without a mildewcide it lifts soiling rather than killing spores; most negative reviews come from buyers expecting one-step mold removal. The cleaner rinses fully so the follow-on Fabric Guard beads as designed.
A good fit for owners who keep an acrylic-canvas top clean and want a fabric-safe cleaner paired with its protectant. Skip it for heavy established mold · clear that with a dedicated mildewcide first. Mohair tops aren't well represented in the review base; Robbins, EZon, and GAHH endorse 303 for acrylic fabric tops.
Cleaner SDS (v1.1, 2019) is GHS Not Classified · no signal word, no H-codes, pH 7-8, no biocidal active. Section 15 is Prop 65 negative for the cleaner; the kit-box Prop 65 and DANGER come from the Fabric Guard bottle's petroleum-distillate carrier. Eye and skin PPE aren't required, and SDS §12 confirms the cleaner isn't harmful to aquatic organisms.
The DANGER signal word and Prop 65 warning printed on the kit box apply to the 303 Fabric Guard bottle inside the kit, not the cleaner. Fabric Guard uses a petroleum-distillate carrier solvent that carries a DANGER signal word and Prop 65 listing per its own SDS. The cleaner's own SDS (v1.1, 2019) is explicitly Not Classified · no signal word, no H-codes, no Prop 65 · and that's what this page's health bar scores. Always follow the Fabric Guard's PPE guidance when applying that step.
No. The cleaner has no biocidal active and is not EPA-registered as a mildewcide. It physically lifts soiling, road grime, and light staining; it does not kill mold spores. Established black mold colonies generally need a dedicated mildewcide first, then this cleaner becomes the routine maintenance step afterward. Reviews from buyers who expected one-step mold removal are the source of most of the kit's negative ratings.
Community reports across multi-season threads on r/AutoDetailing show no documented color shift on black or tan acrylic canvas with the cleaner. The pH 7-8 chemistry, no chlorinated bleach, and no aggressive solvents all support color safety on dyed acrylic. Mohair and other natural-fiber tops are not well represented in the public review base · check material-specific community data before committing.
This kit is the FABRIC variant (303 also sells a separate vinyl-top kit with different chemistry). The cleaner's mild water-based surfactant chemistry is unlikely to harm vinyl panels in incidental contact, but the cleaner-to-protectant system is designed for acrylic canvas · for primarily vinyl tops, the vinyl-specific 303 kit is the correct product.
The kit includes 303 Fabric Guard, which is the manufacturer-paired protectant and the one with the most community data behind the cleaner-then-protectant workflow. The cleaner rinses fully clean, so the Fabric Guard bonds and beads water as designed. Substitute protectants are possible but lose the kit's main quality strength · a documented hand-off between the two products.
