Brush them clean with your dry brush. Use a q-tip to get any grime out of the holes. Put a light amount of polish on with the applier brush. Use your long brush to buff that in. Repeat. I use parade gloss since it takes a thinner coat to get the same shine. Once you get the right amount of wax on there you won't have to add any or much to get the shine back the next time and you'll find the shines last pretty well.
