You can save 90 percent of the cost of maintaining your home by just doing the simple things yourself.
Did I just make myself a huge expensive problem or am I overlooking something? And sorry this is such an unprofessional question, I should have known better than to try and mess with this stuff on my own...
No, you just learned one of those "simple" things. A plugged aerator on a faucet will prevent the faucet from working properly. That is, if the water can't get out of the faucet, it'll seem like the faucet isn't working properly anymore. I can guarantee that whenever you come across this same problem in future, you'll think of checking for a plugged aerator or sprayer.
It's called a "leaning experience", and they can be terrifying. That helps immensely in the memory process.
But, still, what you learned was one of those "simple things" that counts as part of the 90 percent. Someone else woulda called a plumber and paid for a service call only to find out that the sprayer attachment nozzle was clogged. See how some of this stuff can initially be difficult to solve, and turn out to be blindingly obvious?
PS: Maybe don't use harsh cleaners like acids too liberally. You wouldn't have done any harm to your sprayer attachment by soaking it in CLR, but the better way would have been to simply clean the crap out of the sprayer nozzle by hand. That's cuz there's lots of stuff (like plastic and/or particles of metal) that wouldn't have been removed by the CLR, and could still be plugging some of the holes in your spray attachment. It's the same with drain cleaning chemicals; they're best left unpurchased. Put the money toward mechanically clearing the drain with a snake or jetter instead. Those ways are sure to clear the drain, even though the up front costs are higher.
