Product recommendations for preventing limescale build-up on shower doors and tiles

[ourSusie]

does anyone know of a product which can act as a barrier to water
after cleaning the perspex? shower doors and the bathroom tiles please,
in a very hard water area creating limescale - I’m wondering why I’m cleaning
and polishing yet it still looks as though it needs a good scrub

it isn’t possible to have a water softener fitted or we would

Yes car glass cleaning stuff. Is brilliant.
the last I bought was Rain X two in one glass cleaner

Theres a product that you spray on to make water bead off. I think car detailers use it.
I've also read a tip somewhere about spraying the screen with furniture polish once clean to do the same. Not tried either myself. I tend to use Viakal, squeegee and micro fibre cloths. Would love a water softener myself.

method shower spray in passionfruit is good

we use the orange one! but it doesn’t silicone either the expensively tiled shower or the shower doors - they aren’t glass, guess they are something plastic
we have a young sturdy cleaner lady who applies elbow grease twice monthly and now sees these doors as a challenge, two days after she has been they look just the same, its dispiriting
It’s a great shower
I’m considering hanging shower curtains inside the doors or moving

Citric Acid.

Use a Karcher after every shower, on tiles and screen

How long between each application. Shower is used twice a day.

yeah ok

I recommend Astonish white vinegar with zesty lemon.

I use karcher or similar after every shower, no sprays worked, i have the method shower sprays but i don't find it very good.
Viakal is great, but it is toxic so i try to use it once a month only

thanks everyone for the replies

Not preventative, but very effective for removal - white vinegar in water applied with a cloth. Leave for a few minutes and rinse and dry. Sparkling.

I do it once a week, low effort and maximum result.

Our shower mixer tap was really limescaled up when we moved in. We clean shower after every use with Aldi bathroom cleaner & the limescale reduced gradually & now gone completely!
