Translated from the manufacturer’s Safety Data Sheet, Section 8
Cleaner step: 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. Protectant step: the paired RaggTopp Fabric Protectant's own SDS §8 also recommends safety glasses with side shields; its §2 carries a DANGER signal word (flammable aerosol, H226) with no eye-damage H-code, so eye protection here is precautionary for overspray rather than a corrosive-splash risk.
U.S. regulatory standard
29 CFR 1910.133(a)(1)
“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.

Translated from the manufacturer’s Safety Data Sheet, Section 8
Cleaner step: SDS §2 classifies H316 (mild skin irritation, Cat 3); brief brush-agitation contact is low-risk, extended hand-immersion is the trigger for gloves. Protectant step: the paired RaggTopp Fabric Protectant carries its own DANGER signal word (SDS §2: H226 flammable liquid, H304 aspiration toxicant, 70-80% naphtha petroleum distillate) and its §8 explicitly recommends chemical-resistant gloves and chemical/oil-resistant clothing, not boilerplate hedging. Escalated to recommended for the kit as a whole to cover the protectant application step.

Translated from the manufacturer’s Safety Data Sheet, Section 8
Cleaner step: SDS §8 states no respirator is normally required · water-based, no measurable VOC, no flash point to 212°F. Protectant step: the paired RaggTopp Fabric Protectant is a DANGER-labeled flammable aerosol (H226) whose own SDS §11 states plainly 'Vapor/aerosol concentrations above recommended exposure levels are irritating to the eyes and respiratory tract, may cause headaches, dizziness, anesthesia, drowsiness and other CNS effects' and whose §8 names a half-face filter respirator as a real consideration when engineering controls (ventilation) are insufficient. Escalated to recommended for the protectant application step: spray outdoors or in a well-ventilated area.

Translated from the manufacturer’s Safety Data Sheet, Section 8
The paired RaggTopp Fabric Protectant is a Category 3 flammable liquid aerosol (H226, flash point 38-40°C (101-104°F), naphtha petroleum distillate 70-80%). Its SDS §7/§8/§10 call for explosion-proof ventilation equipment, keeping away from heat/sparks/open flames, and no smoking during use. Apply the protectant outdoors or with the garage door open, away from pilot lights and other ignition sources.

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.

Last reviewed July 25, 2026
TL;DR The only convertible top cleaner-and-protectant system endorsed by the Haartz Corporation, the OEM behind most factory fabric tops. Removes light-to-moderate mold and grime reliably on canvas and vinyl in one pass; heavy black mold needs a chlorinated pre-treatment first. The cleaner itself carries only a mild-irritant warning; the paired protectant aerosol is a genuine DANGER-labeled flammable aerosol, so apply it outdoors, away from ignition sources.
A water-based, mildly alkaline surfactant cleaner in a 16 oz pump bottle, paired with the matched RaggTopp Fabric Protectant aerosol. Spray onto a damp top, agitate with a soft brush, rinse with a garden hose. No biocidal active, so established mold needs a chlorinated pre-treatment first. BimmerPost and MBWorld threads report a clean rinse on Haartz canvas, with the matched protectant beading well after.
Strong fit for Haartz factory-top owners (Stayfast, Sonnenland, Twillfast) and OEM vinyl, since it is the system the topping manufacturer itself endorses. Mohair owners should check fabric-specific community data first. Heavy mold does better with a chlorinated remover first, then this kit for ongoing maintenance.
The cleaner's own SDS classifies only mild eye and skin irritation, the source of its WARNING label, and confirms it is not hazardous under OSHA HCS and not Prop 65-listed. Section 8 directs safety glasses for splash and lists no respirator as normally required; the formula's mild alkalinity (pH just above 10) is why gloves help for extended hand-contact. Section 12 confirms ready biodegradability (OECD 301B) with no bioaccumulation and aquatic toxicity well below GHS thresholds. No PFAS, no chlorinated bleach.
The paired protectant aerosol is a different chemistry and carries a genuine DANGER label, visible on the can as "EXTREMELY FLAMMABLE, VAPORS HARMFUL, CONTENTS UNDER PRESSURE." Its own SDS confirms a flammable liquid aerosol (H226) built on a 70-80% naphtha petroleum-distillate carrier, with an aspiration hazard (H304) if swallowed. Apply it outdoors or in a well-ventilated space, away from heat, sparks, open flame, and smoking, with gloves and eye protection. This DANGER hazard belongs to the protectant, not the cleaner scored above.
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.
Yes, it's a different chemistry entirely. The 16 oz cleaner (scored on this page) carries only a mild WARNING label. The paired 11 oz RaggTopp Fabric Protectant aerosol carries its own DANGER label, printed on the can as 'EXTREMELY FLAMMABLE, VAPORS HARMFUL, CONTENTS UNDER PRESSURE.' Its own SDS confirms Flammable Liquid Category 3 (H226) and Aspiration Toxicant Category 1 (H304), driven by a 70-80% naphtha petroleum-distillate carrier. Apply the protectant outdoors or in a well-ventilated space, away from heat, sparks, open flame, and smoking, wearing gloves and eye protection. This DANGER hazard is genuine chemistry from the protectant, not the cleaner, and it doesn't change the cleaner's own scores on this page.
