KLEAN-STRIP PREP-ALL ULTRA Universal Surface Cleaner 1 Gallon — Low-VOC, Non-Flammable Paint Prep & Degreaser

KLEAN-STRIP PREP-ALL ULTRA is a low-VOC, non-flammable universal surface cleaner designed to remove wax, grease, fingerprints and mold-release agents quickly while leaving no residue.

PREP-ALL ULTRA is an emulsion-based cleaner formulated to deliver solvent-level performance with reduced volatile organic compound emissions. It’s intended for automotive, workshop, and household use where fast evaporation, long-lasting activity on the surface, and regulatory compliance are important. The product’s low odor and non-flammable formulation make it practical for indoor workspaces while still providing aggressive cleaning power for paint prep and degreasing tasks.

How does PREP-ALL ULTRA make paint prep easier?

PREP-ALL ULTRA removes contaminants that interfere with adhesion—wax, grease, silicone, and mold-release residues—while evaporating cleanly and quickly. Because it’s an emulsion formula, it stays wet longer on the surface to lift soils but dries without leaving film.

• Effective on metal, fiberglass, plastic, and painted surfaces
• Removes wax and oils that prevent proper coating adhesion
• Fast-drying with no sticky residue to affect primer or paint
• Maintains activity longer than simple fast-evaporating solvents

Can I use this indoors and is it safe around paint booths?

Yes — PREP-ALL ULTRA is non-flammable and formulated to be low VOC, which helps meet stricter ventilation and emissions rules in many states. It’s suitable for controlled indoor environments, including prep areas and paint booths, but standard ventilation and PPE are still recommended for worker safety.

• Non-flammable for safer storage and indoor use
• Low odor for improved comfort during application
• VOC-compliant formulation acceptable in states with stricter limits
• Use with appropriate gloves and eye protection

What’s the best way to apply PREP-ALL ULTRA for consistent results?

Apply with a pump sprayer or lint-free cloth for even coverage; allow the solution to dwell briefly to lift contaminants, then wipe or rinse per job requirements. For large panels, a sprayer gives uniform application and faster workflow, while cloths work well for spot cleaning and edges.

• Use a clean pump sprayer for large surfaces and faster work
• Wipe with lint-free towels to avoid introducing fibers
• Allow a short dwell time to loosen wax and grease before wiping
• Follow surface-specific instructions for best adhesion results

Will PREP-ALL ULTRA damage plastics, trim, or existing paint?

PREP-ALL ULTRA is formulated to be effective without aggressively attacking substrates when used as directed, but testing on an inconspicuous area is recommended for sensitive plastics or aged finishes. Its balanced emulsion provides cleaning power while reducing the risk of softening or streaking common with stronger neat solvents.

• Suitable for many plastics, metals, and painted surfaces with proper testing
• Less likely to leave streaks or residue than some high-pressure solvents
• Test first on trim, decals, or aged paint to confirm compatibility
• Follow manufacturer guidance for delicate or specialty materials

Who this is for: PREP-ALL ULTRA is aimed at automotive professionals, body shops, detailers, marine and composite fabricators, and serious DIYers who need a compliant, fast-acting cleaner for paint prep, degreasing, and general surface preparation. If you work in regulated environments or want to minimize strong solvent odors while keeping cleaning performance, this product provides a balance between safety, compliance, and effectiveness.
