Emmy grabbed a telescope, two cleaning cloths, a bottle of cleaning solution, and a spray bottle of holding cream.
Right! Let's get to work! she thought to herself, smiling.
First, she took the top off tthe bottle of cleaning solution, wadded up her first cloth and placed it over the top of the bottle, and upturned it.

Then, she began applying the solution over the telescope, taking great care to get into all the little creases and crevices. Letting the first coat dry for a while, she glanced round at her fellow students to make sure she was going about it the right way.
