“I have 3 hummingbird feeders, 4 tube feeders, a fly-through, two suet feeders and a bird bath that I sterilize every 7-10 days. As a wildlife rehabber I've seen first-hand the deadly diseases passed from bird to bird. I can't stress how important it is to keep your feeders clean.
This product has made the cleaning process more efficient: I dump the old food, clean out the debris and spray on the cleaner (always scrub the ports on your hummingbird feeders!) Wait five minutes and rinse. The cleaning solution rinses off quickly and leaves no residue. The spray bottle is big, 32 oz. and the spray head is high quality, so the bottle will last a long time. I can happily recommend this product.”
