My water is fairly hard and has deposited hard water scale on my shower enclosure and a couple outside windows (from lawn sprinklers)
Tried Kaboom and vinegar to no avail.
Thanks in advance for any suggestions on how to remove this scale.

You could give CLR a try. We have had good luck with it in the past. https://clrbrands.com/Products...um-Lime-Rust-Remover

I would try CLR.

Man you beat me....

Vinegar. Just got to keep at it. Can take days. Try soaking paper towel in vinegar and laying it on the surface and leaving it there.

Toothpaste will likely work, but may also leave very fine scratches. Try in inconspicuous area first.

Whink found in the laundry stain remover section of the grocery store in a brown bottle.

Make sure windows are not in the full sun. Wet a paper towel heavily, very lightly rub a 1' area of the window with the wet paper towel, when you see the scaling disappear, wipe dry with a dry paper towel (do not allow the wink to dry on the window). Once the entire window is clean, Then rinse them off and rain-x them. We use the rust stain one, in the yachting industry. Whink is cheap and can usually find it in the grocery store and works incredibly well.

The other product that works incredibly well is the IMAR glass polish. Has to be ordered, but is a cream and does an incredible job also.

I bought a product called GroutEEZ on Amazon to clean some stubborn stains in some light colored tile grout. It worked well and I had previously tried every dang thing known to man in the past without success.

Anyway I was cleaning the glass shower enclosure last week and couldn’t get the water stains off no matter what I tried. So I put some GroutEEZ on some shop towels and the stains rubbed right off.

I bought 4 more containers of it.

I might give Barkeeper's Friend a try.

Look into possibly using a clay bar. Walmart carries a kit for around $25. Strip the soap skim with a strong detergent like simple green or Castrol super clean prior.

Look up some videos to get an idea of its effectiveness and usage.

Lately I've started using Blue Dawn mixed half and half with white vinegar. It does amazing things. Let it sit a while, spray again, rinse.

Magic eraser? Do a test area first to verify it will not scratch.

The classics would be CLR and/or vinegar. THey have worked for me. I used the "extra-strength cleaning vinegar".
Lime-away will also work, but I have a really bad reaction to even the slightest whiff of its fumes!

muriatic acid. Wears gloves, face shield and safety glasses and throwaway clothes. Plenty of fresh air. Try diluting 50% water for working solutions.

My water is so hard that when I turn on the faucet, gravel comes out.

Vinegar alone works well for most things. In the shower I use the vinegar/Dawn mix, but I only use about 75/25. No need to waste 50/50 Dawn in the mix. It works just as well at 75/25 and is a whole lot easier to rinse.

I can't imagine using it indoors.
Even a 4:1 water:muriatic solution was pretty strong, fume wise, and that was outdoors.

I have used, with success, Zaino's glass polish and my car buffer.

I had some bad lime spots on some car glass. I took SOS pads and scoured the glass with them. Worked great and didn't hurt the glass or the paint.

I am surprised at this. Years ago a friend loaned his car to an individual who as a favor decided to clean it up good before bringing it back. Front windshield was ruined by him using SOS pads.
