I've been able to use the new bird saver cleaner on numerous occasions since it arrived. As the weather has slowly been warming, it's been a good opportunity to clean all my backyard feeders. The solution has made it much easier to get all the dirt, excrement and other stains off the feeders. It still requires some scrubbing, but after applying the solution and letting it sit a bit, cleaning was not so intense as it usually is! I like that the cleaner is also made specifically for bird feeders since I have not seen anything on the market like it. Worth it!
