FREQUENTLY ASKED QUESTIONS
What makes the Ultra Heavy-Duty Walnut Scrub different from regular mechanic soaps?
Our Ultra formula uses finely ground walnut shells plus high-powered surfactants (soaps) to cut through the toughest grease, oil, adhesives, tar, and paints. It’s designed for professional shops and industrial use.
Does this soap damage skin with frequent use?
No — despite its strength, the formula is balanced with skin conditioners so you can use it multiple times a day without cracking, drying, or irritation.
Will this remove paints, adhesives, and sealants?
Absolutely. It’s engineered to break down stubborn automotive paints, industrial adhesives, caulking, inks, and more.
Is this safe for people with nut allergies?
The walnut shell scrubbers are cosmetic-grade and highly refined. Many customers with mild peanut or tree nut sensitivities use it without issue. However, those with severe nut allergies should avoid this product or consult a doctor first.
Does this soap require water?
Yes — unlike our wipes, the Ultra Heavy-Duty Soap is a water-activated liquid formula. For best results, wet hands first, scrub thoroughly, then rinse.
Will this dry out my hands with daily use?
No — the formula is designed for frequent shop use and includes conditioning agents to help keep skin from cracking or drying out over time.
