Mothers CMX Surface Prep 24 oz — silicone-free, pH-neutral cleaner for coatings

Mothers CMX Surface Prep is a silicone-free, pH-neutral cleaner that removes wax, oils, polishing residue and contaminants to prepare exterior surfaces for lasting ceramic coatings, sealants or wax.

Getting a flawless bond between a coating and your vehicle starts with a surface free of anything that can block adhesion. Mothers CMX Surface Prep uses biodegradable surfactants and targeted solvents to dissolve grease, oils and leftover polishing compounds, then flashes off quickly to leave a clean, residue-free finish. It’s formulated to be safe on paint, glass, trim, wheels and tires, and is free of silicones so it won’t interfere with professional refinishing or bodyshop work.

How does CMX Surface Prep remove waxes and oils?

This formula combines grease-cutting surfactants with solvents designed to loosen and lift contaminants without attacking clearcoat or trim. After spraying and wiping, the solvents evaporate rapidly, carrying away residues and leaving a surface that’s ready to bond with coatings or sealants.

• Biodegradable surfactants dissolve grease and oils
• Solvents break down stubborn wax and polishing residue
• Fast-flashing for quick wipe-off and minimal dwell time

Can I use it on different exterior surfaces?

Yes — Mothers CMX Surface Prep is designed for broad exterior use. It’s safe for painted surfaces, glass, plastic trim, wheels and rubber tires when used as directed, making it a versatile prep step before coating or sealing.

• Paint and clearcoat: removes contaminants without etching
• Glass: clears film and oils for better adhesion and clarity
• Trim, wheels and tires: lifts residue that interferes with bonding

Why is being silicone-free important?

Silicones can impede adhesion and cause issues in bodyshop refinishing or with some coatings. Because Mothers CMX Surface Prep contains no silicones, it won’t leave a film that blocks a durable chemical bond, making it suitable for professional environments.

• Prevents silicone contamination that weakens coating adhesion
• Compatible with bodyshop practices and refinishing processes
• Helps produce a consistent, long-lasting coat adhesion

How simple is the application process?

Application is straightforward: spray directly onto the surface and wipe clean with a microfiber towel. The product is formulated to quickly flash off, leaving an anti-static, dust-resistant surface that’s ready for the next protective step.

• Spray on targeted areas or entire panels
• Wipe with a clean microfiber for optimal results
• No rinsing required; dries fast and residue-free

Who is this for: Mothers CMX Surface Prep is aimed at detailers, professional installers and enthusiasts who need a reliable, silicone-free preparatory cleaner. It’s ideal for anyone applying ceramic coatings, paint sealants or waxes who wants a dependable, residue-free surface for better bond strength and longer-lasting protection.
