I am an N scale railroad modeler. I use these minature drill bits
and pin vises all the time.
I get mine from Micro-Mark http://www.micromark.com/ .
I am not associated with MicroMark in any way wxcept as a customer.
household VINEGAR will remove those mineral deposits,and cheaper than CLR
or Lime-Away. all of them are mild acids.
did you bother to check the Moen website? maybe they have cleaning info.
the "gold"(brass?) plating may be titanium nitride,and not much is going to
brass plating would need a coating to prevent tarnish,TiN doesn't tarnish.
are you familiar with Edgar Rice Burrough's Martian series?
Have you seen Princess of Mars or John Carter of Mars?
I have been told of this one, but I more often am asked
if I am that Dr. John Carter from the old TV series "ER".
I do have a PhD and where I received my degree, they told
me I should use the title, I did only professionally. SInce I
retired, I am just plain old John Cartr.
The problem is Energy Star madness. 14 years ago you could buy a showerhead that
was self cleaning by virtue of the fact that the holes were large enough that
the flow of water would clean the mineral deposits.
These days, Water Sense shower heads are limited to less than 2 gpm, even less
than the previous low flow 2.5 gpm heads. The only way you can get any kind of
performance with that low a flow is to make needle size holes that plug up in
the presence of any kind of mineral deposit.
So you get a crappy shower and get to constantly clean or replace the shower
I would take the shower head off, so I don't get any CLR on the rest
of the stuff.
First, I'd take it off and run a pin backwards thorugh each hole, to
get out little stones. If it's deposits, I'd use somethng just big
enough. I don't see how that could fail.
But if I still wanted to sue clr, if the head disassembles, I'd only
use clr on the plate with the holes.
I decided to take the high road and just submerge the head in a bag of
white vinegar taped around it. Funny but after I got it secured in
place, the bag sprung a leak but with quick thinking, I got tape to
stop it and it worked good enough. I left it submerged for about 9
hours. My wife used the shower after my repair and said it was
noticeably better. In hindsight I should have taken the head off but
I was so careful when I put it on with plumber's tape 6 months
earlier, I didn't really want to disturb it so that was the reason I
took the high road.
