Gently and carefully dry vacuum your upholstery to remove as much surface dirt as possible. In many cases dry vacuuming will remove as much as 70 percent of the dirt and grime from your furniture.
Apply the foam to a foam sponge and gently rub into a hidden spot on your fabric so you can make sure the product is not going to harm the fabric.
Follow the instructions on the bottle of dry foam extraction. This can be found where you purchase upholstery cleaning supplies or at larger fabric stores.
Rub the product into the fabric gently. Dab at the fabric to remove as much dirt and grime as possible.
Press towels firmly against your upholstery to draw out as much of the remaining foam and dirt as possible. Be careful not to stretch or break delicate fabric.
Vacuum your fabric once again while it is still damp.
Blow fans on your upholstery to dry it. Be patient. Drying time after using the dry foam extraction method can be several hours. Do not use your furniture until completely dry.
