Why selected: It provides a dedicated wax and tar removal action in a single quart, helping to prep metal and painted surfaces prior to refinishing. The liquid is designed to dissolve residue that can impede primer and paint adherence.

Why selected: This cleaner is marketed as a professional-grade, fast-drying degreaser that leaves no oily film, improving paint adhesion and finish quality. It’s suitable for multiple substrates around an auto shop or garage.
Caution: As with any strong solvent, ensure adequate ventilation and avoid use on heat-sensitive plastics unless testing first on a hidden area.
Custom Shop KW901 – Gallon Grease And Wax Remover
Best for: Body shops and serious paint projects where maximum grease and wax removal is needed before primer and topcoat.
Why selected: KW901 is described as fast-acting, dissolving grease, wax, tar, adhesives, and silicones to ensure a clean surface. It’s designed to support maximum paint adhesion and quick drying with little residue.

Buying Guide
What should you consider when choosing a wax and grease remover?
Surface compatibility matters. Check whether the product is labeled for metal, plastic, fiberglass, or gel coat, and select accordingly for your project area.
Drying time and residue are critical for adhesion. Prefer fast-drying, residue-free formulas when the goal is consistent primer and topcoat adhesion.
Strength and solvent type influence ventilation needs and substrate safety. Industrial-grade degreasers are strong and may require better airflow and PPE.
Quantity and coverage influence value. Gallon sizes are cost-effective for big projects, while quarts suit smaller jobs or touch-ups.
Application method matters. Some removers require dwell time, pressure, or wipe-down steps. Follow manufacturer guidelines for best results.
