Attach your vacuum's upholstery attachment to the vacuum's hose. Move the upholstery attachment over the surface of the microfiber furniture to remove dirt, dust, hair and other debris.
Open windows and doors to the area you will be working in. This will provide the room with adequate air ventilation. Equip yourself with a pair of rubber gloves.
Dampen a clean cloth with the glass cleaner. Do not spray the glass cleaner directly on the microfiber. Rub the microfiber furniture with the cloth in a circular motion.
Continue rubbing the spots and stains with the cloth. Add more glass cleaner to the cloth if needed.
Allow the microfiber furniture to air dry. Brush the microfiber with a soft-bristled brush after it has dried to keep the fabric from becoming stiff.
