Overview

Meet the Gtechniq W4 Citrus Foam Shampoo and Degreaser, a purpose-built car care solution that blends cleaning power with a gentle touch. The citrus foam clings to vertical panels, helping to lift road grime as you wash. The formulation is non-caustic, which supports safer use around trims and painted surfaces when used as directed. It comes in a 1 L bottle, offering multiple washes while keeping your routine simple and effective. In addition to cleaning, you may notice a fresh citrus scent that enhances the washing experience, making routine detailing a more pleasant task.

The product doubles as a degreaser in tougher spots, yet remains easy to rinse away, leaving a clean, residue-free surface that can reflect light and reveal the original hue of your paintwork. The formula is 100% biodegradable, aligning with eco-conscious cleaning habits without compromising performance. This combination of practical cleaning power and thoughtful formulation makes W4 a versatile option for regular maintenance and quick, satisfying washes.
