Gtechniq W4 Citrus Foam 1L

Traditional car cleaning foams often rely on harsh chemicals that can strip away protective coatings and degrade your car’s surface over time. W4 Citrus Foam is different. This pH-neutral car cleaning foam is engineered to break down road grime, stubborn dirt, and more without damaging your ceramic coating or paint. Infused with a powerful citrus degreaser, W4 Citrus Foam lifts contaminants with ease while delivering thicker foam for superior coverage. Whether you use a foam cannon, foam gun, or pump sprayer, this high-performance formula ensures an even, touchless car wash experience.

For best results, apply W4 Citrus Foam using a 10 parts water to 1 part solution dilution ratio, let it sit, then rinse off with a garden hose or gentle pressure washer. For tougher grime in wheel wells or hard-to-reach areas, use a wash mitt or microfiber towel for added agitation.
