From the manufacturer’s Safety Data Sheet, Section 8
“SDS §2 classifies H320 (eye irritation Cat 2B) and §8 directs P280 'Wear safety glasses with side shields.' Pump-spray application and brush agitation close to the top create a plausible mist/splash pathway to the face.”

From the manufacturer’s Safety Data Sheet, Section 8
“SDS §2 classifies H316 (causes mild skin irritation, Cat 3). SDS §8 recommends normal work clothing only; §11 notes 'Repeated or prolonged exposure may cause skin irritation and dermatitis due to degreasing properties of the product.' Brief brush-agitation contact during a 15·30 minute session is low-risk; extended or all-day commercial use is the trigger for gloves.”

TL;DR The standalone cleaner bottle from the only convertible-top care system endorsed by the Haartz Corporation, the OEM that makes most factory fabric tops. A mild, water-based surfactant cleaner designed for both fabric canvas and vinyl; reliable on light-to-moderate mold and routine grime, though heavy mold may need a second pass or a chlorinated pre-treatment. WARNING label from mild-irritant codes only; the SDS classifies it as non-hazardous. Zero measured VOC, biodegradable by OECD 301B.
A water-based surfactant formula (pH 9.7·10.7, deionized water with non-ionic surfactants, a fatty-acid soap, a tetrasodium chelator, and an alkanolamine buffer) in a 16 oz trigger-spray bottle. The workflow: wet the top, apply evenly, agitate with a soft-bristle brush in circular motions, dwell 10·20 minutes on tough stains, garden-hose rinse. No EPA-registered biocidal active · cleaning is mechanical and surfactant-driven. Owners confirm it restores heavily soiled tops (black mold after a Florida summer) with one or two applications; the same community notes that heavily established deep mold resists without an extended dwell or a chlorinated pre-treatment. Coverage runs about one bottle per full cleaning of a compact or sports-car top; larger tops or heavier soiling may require more.
Strong fit for Haartz factory-top owners (Stayfast, Sonnenland, Twillfast) and vinyl-panel convertibles wanting a cleaner that carries OEM alignment. Also works for Jeep soft-tops and simcon/tonneau covers per the manufacturer. Best suited to regular maintenance cleaning · quarterly or as-needed on a top that is not severely neglected. The Haartz endorsement is the clearest signal in the category for fabric-top owners. Skip it if your top has severe, established black mold: start with a chlorinated mildew remover and use RaggTopp afterward for the follow-up clean. Skip it if you need the cleaner+protectant system · the kit (ASIN B0017TTPE0) pairs this formula with the matched RaggTopp Fabric Protectant.
SDS Section 15 confirms this product is not classified as hazardous under OSHA HCS and is not Prop 65-listed. The WARNING signal word comes from two Category 3 mild-irritant codes: H316 (causes mild skin irritation) and H320 (causes eye irritation, Cat 2B). SDS Section 8 directs safety glasses for splash and states no respiratory protection is normally required. Section 12 confirms biodegradability via OECD 301B Modified Strum Test, no bioaccumulation, and a fathead-minnow 96-hour LC50 of 316 mg/L (100% survival at 100 mg/L) · well below aquatic toxicity thresholds. No PFAS, no chlorinated bleach, zero measurable VOC.
Yes. RaggTopp is the only cleaner-and-protectant system endorsed by the Haartz Corporation, the OEM manufacturer of most factory convertible top fabric (Stayfast, Sonnenland, Twillfast, and other lines). The endorsement covers the RaggTopp cleaning formula regardless of whether you buy the standalone bottle or the kit. If your top is a Haartz fabric, this is the alignment signal that matters most.
The formula is designed for both fabric and vinyl. The SDS lists no chlorinated bleach, no aggressive solvents, and a mildly alkaline pH of 9.7·10.7 · within the safe range for OEM vinyl panels. Owner reviews confirm no cracking, color shift, or surface damage on vinyl across multiple years of use.
Coverage depends on top size and soil level. A 16 oz bottle is adequate for a single thorough cleaning of a compact or sports-car top at normal soil levels. Owner reviews note that a heavily soiled large top (mid-size convertible or Jeep soft-top) may require a second application or a second bottle. Applying to a pre-wetted top and allowing a 10·20 minute dwell on tough stains helps stretch coverage.
It removes light-to-moderate mold and routine staining with a soft-bristle brush and a single application. The formula is a surfactant-based cleaner with no EPA-registered biocidal active · it lifts surface mold mechanically and via cleaning chemistry. Heavy or deeply established black mold may require a second pass or starting with a chlorinated mildew remover before finishing with RaggTopp. The cleaner is best suited to maintenance cleaning on a top kept covered or cleaned regularly.
Yes. SDS Section 12 confirms biodegradability via the OECD 301B Modified Strum Test, which is the recognized standard for ready biodegradability. The same section confirms the product does not bioaccumulate and is not expected to be harmful to aquatic organisms, with a fathead minnow 96-hour LC50 of 316 mg/L and 100% survival at 100 mg/L. This is SDS-confirmed, not a marketing claim.
