Translated from the manufacturer’s Safety Data Sheet, Section 2
H319 (Eye Irritation Cat 2) is classified in SDS §2 at mixture level · brush-application at close range is the primary contact pathway.
U.S. regulatory standard
29 CFR 1910.133(a)(1)
“The employer shall ensure that each affected employee uses 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
No H315 or H317 at mixture level in SDS §2. Amide surfactant at 0.1-0.5% carries an ingredient-level Skin Irrit. 2 classification. Brush agitation with hands in extended contact with the solution is the primary skin-exposure pathway · translates to situational for prolonged use without gloves.

Only when: in enclosed space
Beyond SDS: translated from the ingredient chemistry
No H335, H334, H331, or H330 at mixture level in SDS §2. Application method is pour-and-brush (not pump spray), outdoor, with a rinse-off step. SDS §4.2 mentions 'spray or mists may cause respiratory irritation' as a general precaution, but no H335 is carried at the mixture level and the form factor is brush application, not spray. Outdoor use mitigates inhalation risk; lungs PPE is situational for any enclosed-space application scenario.

TL;DR Removes mold, algae, and embedded road grime from fabric canvas tops reliably with a pour-and-brush workflow and up to an hour of dwell time · heavy established mold typically needs a second pass. No color shift on black canvas in multi-season owner data. Carries a mild eye-irritant warning; water-based with no harsh solvents.
Water-based surfactant formula · no mildewcide, no quat. Removes mold and algae via surfactant action and brush agitation, not biocidal chemistry. Pour into a container, apply with a 2-inch soft brush in sections, allow 10-20 minutes of dwell (up to an hour for heavily soiled tops), then agitate with warm water and rinse with a garden hose (no pressure washer). Owner reviews confirm results on black fabric canvas tops across the full Renovo system workflow · cleaner prepares the surface for Reviver and Ultra Proofer application.
Best fit for fabric canvas convertible top owners dealing with routine mold, algae, or embedded dirt · particularly those running the Renovo three-step care system. Heavy established mold may need a second pass or a dedicated mildewcide-formula cleaner for initial treatment. Community evidence focuses on canvas; vinyl-panel compatibility is less documented.
WARNING signal word. H319 (Eye Irritation Cat 2) at mixture level in SDS §2; ingredient-level Eye Dam. 1 classifications on both surfactants are not carried to the mixture level at working concentration. No H315, H335, or H317 at mixture level. Aquatic Chronic 3 (H412) in SDS §2 · rinse water should not enter storm drains. Biodegradability confirmed in SDS §12 per EU Detergents Regulations.
The manufacturer positions this cleaner for canvas, double duck, and mohair fabric tops. Community evidence is concentrated on black fabric canvas · vinyl-panel compatibility is not specifically documented one way or the other. If your top is vinyl rather than woven fabric, treat this as unconfirmed for that surface rather than assuming it carries over.
Pour it into a container and work it in with a soft 2-inch brush in sections, rather than spraying it on. Owner-documented dwell time runs 10 to 20 minutes for routine soiling, up to an hour for heavily established mold or algae. Agitate with warm water afterward, then rinse with a garden hose · the label explicitly says never use a pressure washer on a fabric top.
The cleaner is the first step, not a standalone finish. Renovo's own three-step system pairs this cleaner with Soft Top Reviver and then Ultra Proofer, and the manufacturer specifically requires this cleaning step to strip grease, dirt, and old coatings before either protectant is applied. Owner reports confirm the hand-off works: cleaner first, then Reviver or Ultra Proofer for the water-repelling finish.
No widespread color-shift or fabric-damage reports turned up in the community record, including on black canvas tops that saw repeated brush agitation. The formula is water-based surfactant chemistry with no chlorinated bleach or aggressive solvents. That said, tan and mohair tops have thinner multi-season data than black canvas, so watch a small test area first if your top is a lighter or less common material.
Best practice is no. The SDS carries an Aquatic Chronic 3 classification (H412, harmful to aquatic life), which is a mixture-level ecological hazard rather than a skin or inhalation concern. Direct rinse runoff toward a lawn or gravel area rather than a storm drain when possible. The formula is also confirmed biodegradable under EU Detergents Regulations, so it breaks down once diluted and dispersed rather than persisting.
