Developed by nanotech experts, it ensures scratch-free cleaning and is trusted worldwide for premium vehicle care. ## Description Introducing the Gtechniq W4 Citrus Foam Wash, a state-of-the-art cleaning product with a degreasing foam agent that provides an unbeatable clean for your car. Citrus Foam boasts a non-caustic formula that rids your car of stains, road grime and bug spatter with ease, leaving your car with a clinically clean finish, as if it had just rolled out of the showroom.Non-Caustic FormulaUnlike traditional pre-wash snow foams that come loaded with caustic chemicals, W4 Citrus Foam is a pH neutral formula that removes hard to shift grime, without damaging sealants, coatings or waxes.Works with Any Gtechniq CoatingWhen you use W4 Citrus Foam, you can rest assured that it will not negatively impact your Gtechniq coating or sealant that you have already applied, as Citrus Foam has been specifically formulated with a 100% biodegradable, pH neutral formula that works in harmony with Gtechniq’s range of coatings. Retains GlossIf you have applied T1 Tyre and Trim, T2 Tyre Dressing, Quick Detailer, Panel Wipe or a number of gloss boosting products by Gtechniq (all available on desertcart), then using Citrus Foam will ensure maximum gloss retention through the excellent lubrication of dirt particles, which in turn minimises the surface abrasion, and promotes gloss retention.Easy To UseShake product well before using this product, and do not apply in direct sunlight. W4 Citrus Foam can be used at a dilution of up to 1:400 through a foam lance, or up to 1:25 through a pump sprayer. Pour one inch (2.5cm) of W4 into a foam lance and fill with warm water, and spray onto the surface of the vehicle from bottom to top. Let the foam settle on the surface for three to five minutes, and then rinse thoroughly with clean waterStore in a cool, dry place – Use within 12 months of opening. Review: Ottimo se usato con una foam gun - Ho preso questo prodotto per la mia auto... L'ho utilizzato con una Foam Hose (pistola schiuma classica no idropulitrice) Il prodotto è ottimo ma credo che dia il massimo con l'idropulitrice Non funziona con un erogatore spray manuale o/e pressione. Ottimo prodotto se si hanno gli strumenti corretti.
