Fill a freezer-quality ziploc baggie with straight white vinegar. Place it over the shower head so the shower head is completely immersed in the vinegar. Use a thick rubber band to secure it. Leave for 30 minutes then remove (pour it down the drain for more cleaning!) and run hot water through the shower head for a few minutes.
