Best spray on shower screen protector (hard water leaving streaks)

[ThePurpleOneWithTheNut]

Can anyone please recommend a spray for shower screens that repels water and stops limescale drying in streaks?

There are a few on the maker and online some quite expensive ones. I just want one that works well. Maybe that only needs applying every so often.

We have a squeegee but need this too I think.

I use the Method one, better than most f the chemical ones.

Thanks Marmalade I forgot about a Method. I like their floor cleaner. Will give it a go.
