From the manufacturer’s Safety Data Sheet, Section 8
“SDS §2 classifies H320 (causes eye irritation) and §8 directs P280 'Wear safety glasses with side shields.' Brush agitation in close proximity to the top can produce splash to the face.”

U.S. regulatory standard

“appropriate eye or face protection when exposed to eye or face hazards from… liquid chemicals…”
ANSI Z87.1 (incorporated via §1910.6)
OSHA standards apply to workplaces. Cited here as the U.S. reference threshold for the underlying hazard class.

From the manufacturer’s Safety Data Sheet, Section 8
“SDS §2 classifies H316 (causes mild skin irritation, Cat 3). SDS §8 recommends only normal work clothing; §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 hand-immersion or all-day commercial use is the trigger for gloves.”

From the manufacturer’s Safety Data Sheet, Section 8
“SDS §8 states 'No personal respiratory protective equipment normally required.' No H335, H331, H334, or H330 at mixture level. The formula is water-based with no measurable VOC (USEPA 601/602/608) and no flash point to 212°F. Standard outdoor application is well below any inhalation-pathway concern; situational tier captures the rare enclosed-garage scenario only.”

TL;DR The only convertible-top cleaner-and-protectant system endorsed by the Haartz Corporation, the OEM that makes most factory fabric tops. Reliable on light-to-moderate mold and routine grime across canvas and vinyl; heavy black mold needs a second pass · a maintenance cleaner, not a chlorinated mold remover. Carries a WARNING label for mild skin and eye irritation; the SDS doesn't classify it as hazardous.
A water-based surfactant cleaner (pH 9.7-10.7, deionized water with non-ionic surfactants and a fatty-acid soap) in a 16 oz pump bottle, paired with the matched RaggTopp Fabric Protectant aerosol. Spray onto a damp top, agitate with a soft brush, dwell briefly, garden-hose rinse. No EPA-registered biocidal active · established black mold needs chlorinated pre-treatment. BimmerPost and MBWorld threads report clean rinse on Haartz canvas; the matched protectant beads well after.
Strong fit for Haartz factory-top owners (Stayfast, Sonnenland, Twillfast) and OEM vinyl wanting a system aligned with the topping manufacturer's approval. Mohair owners should check fabric-specific community data first. Heavy mold is better handled with a chlorinated mildew remover first, then RaggTopp for maintenance.
SDS Section 15 confirms not classified as hazardous under OSHA HCS and not Prop 65-listed. WARNING comes from Cat 3 mild-irritant codes (H316 skin, H320 eye); Section 8 directs safety glasses for splash and lists no respirator as normally required. Section 12 confirms ready biodegradability (OECD 301B), no bioaccumulation, and a fathead-minnow 96-hour LC50 of 316 mg/L · below GHS aquatic toxicity thresholds. No PFAS, no chlorinated bleach.
Yes · RaggTopp is the only cleaner-and-protectant system endorsed by the Haartz Corporation, which manufactures the topping fabric for most factory convertible tops, SUV soft tops, and tonneau covers. The endorsement covers both the cleaner and the protectant components of this kit. If your top is a Haartz fabric (Stayfast, Sonnenland, Twillfast, and other OEM lines), the Haartz endorsement is the strongest external alignment signal in the category.
It will remove light-to-moderate mold and routine staining with a soft-bristle brush and a single application. The formula is a surfactant-based cleaner · it lifts soil and surface mold mechanically and via the cleaning chemistry. It does not contain an EPA-registered biocidal active (no quaternary ammonium compound, no benzalkonium chloride). Heavy or established black mold colonies typically require a second pass, or starting with a chlorinated mildew remover before finishing with RaggTopp. For routine maintenance cleaning on a top kept covered, the kit is well-suited.
Community data does not document color shift or vinyl damage at normal use. The formula is pH 9.7-10.7 (mildly alkaline), contains no chlorinated bleach, and no aggressive solvents · the SDS Section 3 composition is essentially water, mild surfactants, a fatty-acid soap, an alkanolamine pH buffer, and a tetrasodium chelator. The Haartz endorsement reflects compatibility testing against OEM fabric formulations. Independent community evidence is strongest for acrylic canvas (Stayfast/Sonnenland) and vinyl panels; mohair compatibility is less documented.
Yes · SDS Section 12 confirms biodegradability via the OECD 301B Modified Strum Test, which is the recognized test for ready biodegradability. The same section confirms the product does not bioaccumulate and reports a fathead minnow 96-hour LC50 of 316 mg/L with 100% survival at 100 mg/L, which is well below the GHS aquatic-toxicity thresholds. This is SDS-confirmed, not a marketing claim.
The WARNING signal word is driven by two Category 3 hazard codes: H320 (causes eye irritation) and H316 (causes mild skin irritation). Both sit one GHS category below the codes that would meaningfully escalate the safety profile (H319 and H315). The same SDS Section 15 confirms the product is 'not known to be a Hazardous Chemical as defined by the OSHA Hazard Communication Standard' · the WARNING label reflects the mild irritant statements, not a serious hazard classification.
