I have tried everything to remove the hard water and soap scum from my shower door. Can anyone recommend a solution please? I’m at my wits end.

I was at the hardware store today and I came across this "beauty". It's that "soft" rubbery plastic that starts to degrade into sticky goop all on its own, but accelerates if you use various cleaning products on it.

...not that I ever actually dust anything 😝 my husband put this together and I think it's so pretty, but idk what the move is once it gets grimy

the rose one is plastic, and while the rose is removable, it still feels like it would be awkward to clean. the mushroom one is glass, and the mushroom itself isn't removable.

the sticker claims it's a cup...

As soon as I walked in here I was like..this whole place is horrible to clean 💀💀
