5.2 Dry Foam Cleaning.

Whilst various machines and techniques are used for dry foam cleaning,
they all rely on the use of a special shampoo.

The principle is that water and detergent are applied as foam, so less
moisture is present. The shampoo crystallises as it dries, trapping the
dirt, which is vacuumed away when the carpet is dry.

Advantages are fast drying times and no risk of over wetting.
Disadvantage is that, in my opinion, it is only a surface clean.
