In all due respect we're not talking about nylon!!!!And I will ask why is it you find so important to remove loose fibers that belong to the rug in the first place? Those fibers belong there all that matters is they be clean. Just like a staple fiber nylon loosing it's fibers. Everytime it's vacuumed you will remove fiber. It happens, and you nor anyone else will ever stop it until the rugs looses all its fibers.
Often times after cleaning a finite wool rug if the previously broke loose fibers are not removed during the cleaning process
They will be by the customer every time they walk on it they'll be leaving a trail of little tiny hairs but you would know that you're supposedly the best lol
yes they originally belong to the rug but through decades of being walked on they break loose and need removed by a professional
Please go to school!!!!
