From the manufacturer’s Safety Data Sheet, Section 8
“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.”

From the manufacturer’s Safety Data Sheet, Section 8
“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's Analysis
Last reviewed May 17, 2026
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.
What it is and how it performs
Spray onto a damp top, agitate with a soft brush, rinse with a hose. Community reports on r/AutoDetailing and Amazon 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.
Who should buy this — and who should skip it
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.
Safety and environmental impact
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.
Frequently asked questions
Why does the kit box have a DANGER warning if the cleaner is GHS Not Classified?▾
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.
Will it remove black mold from my convertible top in one pass?▾
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.
Is the cleaner safe on tan or light-colored canvas?▾
Community reports across multi-season threads on r/AutoDetailing and Amazon verified reviews 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.
Does the cleaner work on vinyl panels (like the rear window surround)?▾
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.
What's the right protectant to pair with this cleaner?▾
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.

Excellent product, highly recommend it
If I could give this 10 stars for excellence, I would. Our awnings were continually covered with mold and algae in the spring after a long winter and were horribly tedious to clean. Last year we cleaned them thoroughly in the spring and applied 303 Fabric Guard in the early fall. This spring, they appeared brand new and needed no cleaning! It is an amazingly effective product and well worth the competitive price. It was very easy to apply and dries perfectly clear on the Sumbrella awning fabric. A must have for maintaining awnings.
