Why Limescale Returns to Shower Glass — and How to Reduce It

You clean the shower screen, it looks clear, and a few days later the white marks are back. The main reason is simple: every shower leaves mineral-containing water on the glass. When those droplets dry, the minerals remain.

Why repeated cleaning is not enough

Fresh deposits may be easy to remove, but older mineral buildup can become much harder to shift. That is why the preparation stage matters. Protection should only be applied to glass that is genuinely clean and suitable for treatment.

Older glass: prepare first

CristalCare Glass PowerBlock is the preparation route for glass with existing mineral buildup. It is used before protection where required.

Then protect the glass

CristalCare Basic Set combines ActiveClean with the glass-protection treatment. The objective is not to make maintenance disappear, but to make the treated surface less prone to holding water and deposits.

What still matters afterwards

• Do not let water sit unnecessarily on the glass.
• Use maintenance methods compatible with the treatment.
• Do not apply protection over scale, soap residue or unsuitable surfaces.

On the Costa Blanca, local water conditions can make shower-glass maintenance especially noticeable. A good preparation-and-protection routine is therefore more useful than repeatedly changing cleaners.
