Red clay is a type of moist soil that gets its color from iron oxide. Walking through red clay and then onto your carpet can leave a ghastly stain. Luckily, however, this stain doesn't have to ruin your carpet. You can remove most red clay stains if you treat them properly. The removal of a red clay stain from your carpet will improve the look of your room and make your carpet a clean, attractive area once again.
Refrain from treating the stain until the red clay is completely dry.
Sweep larger pieces of dried clay into a dustpan and discard them.
Vacuum the area to remove more of the clay sediment.
Combine 1 tsp. of liquid dish soap with 1 cup water and mix well.
Moisten a clean, white cloth with the soapy water and use it to dab the stain.
Blot the area dry with a dry, white cloth.
Moisten a white cloth with white vinegar and dab the stain again.
Blot the area dry once more.
Continue dabbing the stain with vinegar or soapy water and blotting it dry until there is no sign of the red clay.
