I recently bought a shag rug for my living room. Not realizing that the motor/actuator for my electric recliner sat directly over the floor, the fibers got caught in the actuator which is now seized and no longer functions. The motor is still fine, however, so if I could find a way to dissolve the polyester fibers and clean up the actuator I could get it working without having to buy a $170 replacement.
For further clarification, the actuator is a large metal screw with a plastic piece that fits over it like a ring on a finger. The plastic piece gets bolted to the recliner’s internal hardware. The only other way to “fix” it that I can think of is to break off the plastic piece but I am unable to find a replacement part.
Polyester is pretty non-reactive, but I’ve read they use DMSO to dissolve it out of Poly/Cotton blends for recycling.
