7. Grab the lamp by the cylindrical glass body and clean the window by
rubbing it against the polishing pad. Use a circular motion and try to
keep the window surface flat relative to the pad. Five seconds of
rubbing will be enough in most cases. Another indication of cleaning

during the procedure (
Figure 7–9 ).
