Instead of coating the surface of a fabric or fiber, like all other stain protectants, MicroSeal actually penetrates to protect the fabric or fibre from within. In fact, MicroSeal was engineered to mimic the natural protection that wool possesses before it is sheered from the animal. And MicroSeal works in much the same way. It is difficult to imagine something like wine permanently staining an animal’s coat. This is because the fur is protected from within by oils. MicroSeal actually offers these same properties to virtually all fabrics and fibres. And because MicroSeal does not coat the surface of the fabric or fibre, it cannot be washed away by regular cleanings.
