Impossible-to-remove hard water deposits

I will be astonished if anyone can help solve this.

I've tried: vinegar, CLR, anti-rust gels, various other anti-lime products and am now into sulfamic acid.

W.T.F. ?????

There is a very thin layer of calcium carbonate still remaining on the glass shower door, no matter what I try! 3 days soaking in vinegar? Nope. I thought CLR was the ultimate solution but nope, doesn't seem to do a damn thing.

Help? I really don't want to resort to HCl (muriatic acid) but I will if someone knows that will work and won't etch the glass.

This is the most frustrating DIY thing I've ever encountered.

Any creative solution thoughts? I know the idea is to dissolve the calcium carbonate with an acid, but cannot for the life of me figure out why it isn't happening.

Even those magic erasers don't touch it.

i've always had excellent luck removing all kinds of deposits on glass, porcelain and stainless with a paste of BKF. a non toxic cheap thing to try anyway

just made sure to keep it wet and used a holder like this and never had an issue. i would think a shower door is tougher than a stove top

I just tried the razor to make sure that it *does* at least come off, and indeed it does, but man.... what happened to chemistry?!?!? Why isn't chemistry working?

First was using vinegar as the wetting agent, then went to water.

Is there any chance that I'm actually shaving away layers of the glass?? Can a razor blade do that?

For the ring of really nasty lime deposits in the toilet, I use a pumice stone from the beauty section at Walgreen's. It's work.

Once the scuzz is off the shower door, go to a bath and bedding store and get a small plastic squeegee to hang on a press on hook near the outside of the shower. Just squeegee it down after using and you'll have little trouble with lime deposits.

Lime deposits are why I cringe at those glittering all glass shower surrounds on HGTV.

over a tub and a 10 second zip with the squeegee does it.

I just wish there was an easy fix for the toilet bowl scuzz besides getting in there every day with the pumice stone. Yuck.

use white vinegar and get it very hot but not boiling.....
mix with blue Dawn dishwashing detergent 50/50.
squirt or spray on thickly back to back about 10 min apart (i reheated it in-between)

use the hottest water from your shower spray and rinse well using a microfiber cloth to help dislodge
any problem areas.

that's it!

I use the rain guard on after I get it clean - two coats - let it dry in-between then
polish the glass. warning!!! keep a window cracked and a fan going when you do the
rain guard. it's very strong and dangerous smelling.
