The key to removing mud stain is to let it dry completely before tackling it. Do not be tempted to apply any treatment whatsoever unit the deposit has become hard and you can brush it off easily. After that, you can work on the stain that has been left behind.
On Carpets Persistent Marks Use Either a carpet-spotting kit or a little denatured alcohol to remove traces of color that remain after removing the deposit. Vacuuming carpets, let mud dry (this usually takes one or two hours), then vacuum up the deposit, if necessary, use a stiff brush to loosen the dried mud first.
