Create a mixture of 2 cups warm water and 1/4 tbsp. liquid dish detergent.
Mix the ingredients until the water suds.
Submerge a microfiber cloth into the soapy mixture. Wring out the cloth until it is damp, not soaking wet.
Wipe down the dustcover's entire surface, inside and out, with the soapy mixture to remove any dust, dirt or grime without scratching the fragile plastic.
Dampen a second microfiber cloth with plain water and wipe down the dustcover to remove any soapy residue.
Allow the dust cover to dry completely before wetting a microfiber cloth with plastic polish. Work the plastic polish into the dustcover’s surface using overlapping circles.
The polish will restore the dustcover’s appearance and shine.
