EVEN FOUNTAINS NEED TLC – The wind, leaves, dirt, rain, snow and birds may make the maintenance of your outdoor fountain challenging. However, indoor or outdoor, keep your fountain clean at all time and the pumps and filters in good working order. Change the water often. There are lots of commercial products but it is best to use all natural cleansing products if you have small children, pets or wildlife to remove algae. A cloth or a sponge with gentle soap should remove the dirt; for tougher stains, use an old toothbrush to scrub them away. To remove calcium, the white scale that develops from harder water, use a mixture of white vinegar and water. If your fountain has decorative stones, clean them the same way as the fountain. Always test your cleaning method on a little hidden spot to ensure it won’t affect the finish.
