Grease Gone - Marine Grade Degreaser

Grease, oil, and heavy contamination don't respond to soap — they respond to Grease Gone. This specifically formulated Marine-Grade Degreaser cuts through engine grease, bilge grime, fuel residue, and stubborn oil buildup on contact. Engineered for the tough jobs in engine rooms, bilges, and heavily soiled surfaces, where standard cleaners just push the problem around.

Spray, Scrub, Rinse.

Key Features:

- Cuts through grease, oil, and heavy marine contamination

- Marine-grade formula engineered for engine bays, bilges, and soiled surfaces

- Works on a wide range of surfaces, including metal, fiberglass, and painted areas

- Fast-acting — apply, agitate, rinse

- Made by detailers

- Made in the USA

How to Use:

⚠️ DO NOT use Cast Off and Grease Gone together, or on the same surface in the same session. Rinse thoroughly between products. Allow surfaces to fully dry before applying a different Mad Soaps product. ⚠️

1. Gear up. Wear protective gloves and eye protection. Always.
2. Cool the surface. Never apply to hot engines or hot metal - let everything come to room temperature.
3. Pre-rinse the work area. Wet down surrounding surfaces (especially anything in the AVOID list below) to dilute any drip-off.
4. Spray directly on the soiled surface. Coat evenly. Do not let the product dry.
5. Agitate if needed. Use a stiff brush, detail brush, or wash mitt depending on the job.
6. Dwell 1–3 minutes. Heavier buildup needs more dwell - never let it dry on the surface.
7. Rinse thoroughly with water. Pressure rinse if available. Make sure all residue is flushed.
8. Repeat for heavy buildup. Stubborn jobs may need a second application.
9. Reapply protection. Grease Gone strips wax, sealant, and ceramic coatings. Apply Boost coat to re-protect.

Ready-to-use formula. No dilution required.

🚨 NEVER MIX WITH:

Mixing Cast Off with the following produces toxic chlorine or chloramine gas:

• Acidic cleaners — vinegar, citric acid, lime/scale removers, rust removers, hull cleaners, toilet bowl cleaners
• Ammonia-based cleaners — many glass and surface cleaners contain ammonia
• Other Mad Soaps products — until you confirm compatibility
• Pool chemicals
• Any "natural" or unlabeled cleaning product of unknown chemistry

If you smell a sharp, sour, or chlorine-like odor more intense than the product itself — stop, ventilate, leave the area, and rinse the surface with large amounts of fresh water.

✅ Safe to Use On

• Stainless steel (rinse promptly to prevent water spotting)
• Cast iron engine blocks (cooled)
• Steel surfaces (rinse fully — alkaline residue can promote flash rust)
• Concrete shop floors and pads
• Porcelain
• Glass (rinse promptly)
• HDPE and polypropylene plastics
• Cured marine paint and gelcoat (short contact + thorough rinse — always test in an inconspicuous area first)
• Bilges and bilge components (rinse fully before discharging any water)

❌ Do NOT Use On

Grease Gone reacts with soft metals and damages many decorative finishes. Avoid contact with:

• Aluminum (any grade — reacts violently, causes pitting and etching)
• Anodized aluminum (strips the anodized layer)
• Zinc anodes (reacts and degrades them — mask off before degreasing nearby)
• Galvanized metal (strips the zinc coating)
• Brass and bronze fittings (can tarnish and etch)
• Copper (reacts over prolonged contact)
• Polished metal trim (will dull and oxidize)
• Carbon fiber components (can attack the resin matrix)
• Vinyl wraps and decals (softens adhesive — will lift edges)
• Leather and vinyl upholstery (causes permanent damage)
• Acrylic and plexiglass (clouds the surface)
• Polycarbonate (causes crazing and clouding)
• Tinted windows (can damage the tint film)
• Rubber gaskets and seals (degrades over time with repeat exposure)
• Soft plastic trim and bumpers
• Wood or wood veneer
• Painted decorative surfaces, clear coats, and automotive paint (will strip and dull)

Rule of thumb: If you can't replace it easily or it's a "soft" metal, mask it off, move it, or skip it.

Pro Tips from the Field

• Always rinse promptly. Don't let Grease Gone sit beyond 3 minutes - the longer it dwells, the more aggressive it gets.
• Mask off zinc anodes before degreasing engines or bilges.
• Pre-wet adjacent surfaces so any overspray is already diluted before it lands.
• Work in shade and cool conditions — heat accelerates the reaction and increases aerosol exposure.
• Rinse with fresh water, not seawater — saltwater can leave deposits behind.
• Rewax or reseal everything you cleaned. Grease Gone removes all protection. Apply Boost Coat after the surface is dry.
• For engine compartments, spray onto a brush instead of directly on the engine when working around electrical connections.
• Marina/dockside use: Capture rinse water with absorbent pads when possible. Do not discharge into the water.
