Oh man, same here - I was forcing myself to use a pocket notebook for months because I liked how it looked, but my handwriting kept getting smaller and smaller. Finally switched to a bigger size and felt like an idiot for not doing it sooner, right?

Hold on a second. I mean, yeah, vinegar works but is it really that big of a deal? I just change heads maybe every two years when the pressure bugs me. They're, what, like fifteen bucks at the hardware store. I guess if you're dead set on saving every penny or you have some expensive fancy rain shower thing, a vinegar soak makes sense. But for me, it takes me longer to unscrew the head and dig out a baggie than it does to just grab a new one off the shelf. It's fine, do what you want, but I don't think you're some genius for cleaning a shower head with kitchen stuff.

Been there man. After chasing my tail for two days on a similar issue I finally just started wiggling wires and found a corroded connector. Now I always check the simple stuff first before buying parts, saves me a headache and my wallet.

Flip it around and ask yourself why you trusted your cousin without checking the basics first.

Taking a loss like that is a hard teacher, but it usually only happens once before you start questioning everything people tell you about money.
