Review on Supco MO44 Buster Liquid Penetrating by Patrick Hamman

I don't know what I was expecting, maybe a miracle. I have a shower head that costs 24 years. I couldn't do it with a wrench and a vise. I've tried WD-40 twice, giving it time to "suck in" but to no avail. I almost ruptured my stomach trying to relax him. Nothing at all. I don't know what's in this rust remover, but it appears to be more volatile than WD-40. I've tried this twice and both times allowed it to "flow" into the streams. Nothing at all. Nothing "breaks". Useless. I have to say that I feel like this expensive product seems designed to just keep me out of my money.
