Pins That Didn't Work

I always go to Pinterest hoping that there is going to finally be an answer to soap scum once and for all. I tried denture cleaner, baking soda, baking soda and vinegar, and a few others that I can't even remember. Pinterest is fine to see stuff that I want like a wedding dress, new bathroom towels or ombre hair. The actual tips never work out for me. I was just working on one spot on my sink and I still never was any better off with any of these homemade cleaners. Granted, even the store bought chemical ones don't work for the sink. Have you ever use a pin that came out exactly like you expected?
