## Description

W4 Citrus Foam - High Content Foaming Agent, Removes Dirt and Road Grime, Non-Caustic Formula, Maximum Gloss Retention Snow Foam (5 Liter)

## Features

- STRONG FOAMING AGENT: The Gtechniq W4 Citrus Foam is a powerful car wash cleaning product that provides you with a high foam content that is unlike most traditional pre-wash snow foams that come loaded with caustic chemicals. W4 Citrus Foam boasts a supreme dirt and grime removal formula that is 100% biodegradable, and removes hard to shift dirt and grime from your vehicle’s paintwork, leaving you with a crystal clear finish
- USE WITH ANY GTECHNIQ COATING: W4 Citrus Foam is comprised of a pH neutral formula that is tough on dirt, road grime and bug spatter, and is specifically formulated to work in harmony with Gtechniq’s wide range of sealants, coatings and waxes. Feel confident when you apply this product, and enjoy a clinically clean finish, with your car looking like it’s just left the showroom
- MAXIMUM GLOSS RETENTION: The W4 Citrus Foam has a non-caustic formula that combines an effective citrus degreaser with a strong foaming agent. This exact combination ensures maximum gloss retention through the excellent lubrication of dirt particles, which in turn minimises the surface abrasion, and maximises gloss retention
- EASY TO APPLY: Shake product well before using this product, and do not apply in direct sunlight, for best results use in a snow foam lance. Decant one inch (2.5cm) of W4 into a foam lance and fill with warm water. Spray onto the lower surfaces of your car and work upwards. Leave the foam to dwell on the surface for three to five minutes, and then rinse thoroughly with clean water to remove all surfactants. Do not allow the product to dry to the car
- 100% CUSTOMER SATISFACTION: We at Gtechniq are as passionate about the quality of our products as we are about the assistance and stellar service that we provide to each and every one of our customers
