For such refurbish tasks I have simply taken some colour tins from
Revell M5 or SM301 (white, not shiny) from the nearest hobby shop
dealing with plastic models. The varnish can be applied into the recess
of the knobs as described earlier in this subject.
Best regards.

After rubbing in, the excess can be wiped off with a cloth. For the perfectionist, white paint can be used to repaint the pointers. Sometimes just soaking in soap water and light brushing can restore the brightness but rubbing too hard can remove the paint.
