Step 4 · Apply Cleaning Solution and Agitate

Dampen a soft-bristled brush or a clean sponge with the prepared cleaning solution. Work on one small section of the rug at a time. Gently brush or sponge the solution onto the rug pile, following the direction of the fibers. The aim is to lift the soil from the surface and upper layers of the pile, not to force the solution deep into the rug. Be mindful of the rug's backing; try to avoid saturating it, as this can weaken the glue and cause delamination. If the rug is small enough and you have a suitable area, you can use a bucket to very carefully pour small amounts of the solution, but a brush or sponge offers more control.
