ArmorAll® Tire Foam is formulated from the same basic ingredients found in Armor All® Protectant, but Tire Foam has a greater proportion of cleaners for the extra needs of dirty tyres. The only additional ingredients are aerosol propellants and foaming agents.
These foaming agents produce the foam but they also hold the active ingredients in place on the tyre sidewall so the cleaners have a chance to do their work. Then, as the foam breaks down, the dirt and cleaning agents are carried away and the protection and beautification ingredients can penetrate the rubber.
Tire Foam is economical, treating up to 35 tyres and there's no need for extra rags or sponges. It is also ozone friendly, uses no CFCs and it will not damage wheels or paints.
