Grandpa Gus's Heavy-Duty Walnut Shell Hand Scrub, 1 Gallon — Solvent-Free Biodegradable Degreaser

Grandpa Gus's Super Hand Scrub is a heavy-duty, biodegradable walnut shell hand soap formulated to remove grease, paint, tar and adhesives for mechanics and construction crews.

This one-gallon industrial hand scrub blends natural walnut shell exfoliants with solvent-free cleaning agents and superior emollients to clean deeply without stripping skin. Designed for professional environments—auto shops, construction sites, manufacturing floors—this formula tackles stubborn soils while remaining phosphate-free and safe for typical drain systems. The product offers a balance of abrasive action and skin-conditioning ingredients so hands come away clean yet hydrated.

How does this scrub remove tough grease and adhesives?

The walnut shell particles provide mechanical abrasion to lift and dislodge heavy oils, tar, and adhesives while the detergent base breaks up hydrocarbons for easy rinsing. No harsh solvents are used, reducing inhalation risks and protecting many drain lines.

• Biodegradable walnut shell scrubbers for physical removal of soils
• Solvent-free detergent system that emulsifies grease
• Formulated to rinse clean without leaving residue

Will it dry out or irritate hands after repeated use?

Unlike many industrial degreasers, this scrub contains emollients that help moisturize skin during and after cleaning, minimizing dryness. While mild irritation is unlikely for most users, avoid contact with eyes and do not ingest; seek medical attention if adverse reactions occur.

• Added emollients to help preserve skin softness
• Gentle abrasives avoid aggressive chemical stripping
• Follow usage and storage directions for best skin safety

How should I use the one-gallon container in a busy shop?

Dispense a small amount into palms or onto a cloth, rub thoroughly over knuckles, palms, fingers and backs of hands, then add water to lather and rinse. The concentrated one-gallon size is ideal for wall-mounted pumps, refill stations, or central wash areas in high-traffic workplaces.

• Apply directly to dry or wet hands; rub, add water, lather, and rinse
• Use with bulk pump or refill smaller dispensers for convenience
• Store between 40–100°F and keep out of reach of children

Is this product environmentally safe for drains and disposal?

The formula is biodegradable and phosphate-free, formulated to be safe for standard drain systems when used according to local disposal regulations. It avoids harsh solvents that can damage drainage infrastructure, but follow workplace waste guidelines for large-volume disposal.

• Biodegradable walnut shell and surfactants reduce environmental persistence
• Phosphate-free to limit impact on water systems
• Avoid large-scale pours; consult local disposal rules for bulk waste

Who is this for: Grandpa Gus's Super Hand Scrub is tailored for automotive mechanics, construction workers, maintenance teams, and industrial technicians who need a reliable, heavy-duty cleaner that removes grease, paint, tar, adhesives and wax without resorting to aggressive solvents. The one-gallon format suits busy shops, service bays, and maintenance departments seeking economical refills for wall dispensers or sink stations.
