Rinse your gold coffee filter after every pot of coffee. Dump out as many grounds as you can, then run the filter under hot running water until all the grounds are rinsed off the mesh.
Place your gold coffee filter in the dishwasher once a week. Set the filter in the top rack of the dishwasher, because the plastic parts may melt in the bottom rack.
Scrub your gold filter by hand once a week if you don't have a dishwasher. Squirt a small amount of dishwashing liquid onto a plastic dish brush. Scrub the inside and outside of the gold mesh with the brush. Rinse the filter completely until all the soap residue is gone.
