Do stain protectors work? Yes, but some work better than others.
All stain protectors work by covering the threads in a fabric or carpet with a soft, flexible coating. Because they are soft and flexible, they generally don’t last very long as they get worn away by use and no longer keep stains at bay.
But before they get worn away, they generally work well. The coating bonds to the fibres without making them stiff and hard to the touch. They will keep most liquids from being absorbed into your carpet or fabric but you must remember to clean the spill up because otherwise the liquid will eventually seep into the fabric. The protector will only protect for a limited time.
Of course, the better the stain protector, the better the job it will do and you can’t get a better stain protector than FabProtection™ used exclusively by FabAgain™. Ok, you know what to do.
