Alles wat er via die opening in valt, komt uiteindelijk op de spiegel terecht. Stof laat zich nog wegblazen, maar een spiegel schoonmaken is werk dat je liever niet doet en dat de coating niet ten goede komt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Deze kap sluit de opening af zodra je klaar bent met waarnemen.
