Gtechniq W6 Iron and General Fallout Remover is formulated to offer you the safest and most effective method of removing potentially damaging fallout commonly found on your vehicles paintwork and rims. In addition to its exceptional fallout removing function, it also has a corrosion inhibitor plus, an additive designed to combat the effects of acid rain. It is a thick gel-like formula that will cling to vertical surfaces. Usage - Use in a well ventilated area out of direct sunlight as the product has a very strong and unpleasant odour. Remove loose dirt using a hose or jet wash. Spray W6 directly onto the surface and allow to dwell for 5-10 minutes. During this time any ferrous particles will dissolve forming a purple solution. Do not allow product to dry on the surface. Rinse residue and repeat if necessary. In extreme cases you can also agitate surface with a Gtechniq MF1 ZeroR Microfibre Buff Cloth.
