Wire brush refill.
These dual purpose Johnston Compact and Schmidt Swingo wire brushes are returned by customers to the Northern Municipal Spares factory in Halifax. This is where the wire is mechanically removed and the plastic disk is cleansed prior to the installation of new wire. These Compact disks can be refilled over 12 times!
Polypropylene brush refill.
Many polypropylene filled compact brushes can be refilled. It is a simple process whereby the old polypropylene monofilament is striped out and sent away for recycling. The plastic top is then cleansed and refilled with new polypropylene bristle ready for shipping back to the customer.
