Practical Guide: How to Clean Polished Porcelain Tiles

How to Clean Polished Porcelain Tiles Without Streaks and Dull Films

Polished porcelain tiles are highly valued for their elegant appearance and their ability to enhance both residential and commercial spaces. However, because they reflect light so effectively, they tend to highlight streaks, dull spots and marks visible in backlighting.

This guide explains when to take action and how to properly clean polished porcelain tiles using the Marbec system.

Why Polished Porcelain Tiles Lose Their Shine Over Time

The main issue affecting polished porcelain tiles is the formation of limescale films caused by household water.

In many areas, water contains high levels of calcium and magnesium. These minerals settle on the surface and create a thin film that:

• reduces the shine;
• creates streaks visible in backlighting;
• makes the surface harder to keep uniform.

Over time, a greasy film may also build up due to foot traffic, cooking vapours and unsuitable cleaning products.

When Is It Necessary to Take Action

Take action when:

• the floor loses its shine and appears hazy;
• water streaks appear after cleaning;
• the surface looks dull in backlighting;
• the polished porcelain tiles always look dirty even after washing.

Recommended Cleaning System for Polished Porcelain Tiles

The Marbec system includes 3 levels of treatment, depending on the condition of the surface.

Routine Descaling Cleaning (Anti-Limescale)

Product: GRES BRILL®

GRES BRILL® is the specific cleaner for the routine maintenance of polished porcelain tiles. It is ideal for removing and preventing limescale films caused by household water.

👉 On polished porcelain tiles, limescale is almost always the main cause of streaks, so routine cleaning should focus on descaling.

How to Apply

• dilute 20–50 cc of GRES BRILL® in 5 L of water;
• apply like a standard cleaner using a microfibre cloth;
• do not rinse;
• also suitable for scrubber dryers.

👉 Keeps polished porcelain tiles shiny and helps reduce water streaks.

Periodic Degreasing Cleaning

Product: GRES LINDO®

GRES LINDO® is recommended for deeper periodic degreasing when polished porcelain tiles accumulate greasy contaminants caused by:

• cooking vapours;
• foot traffic;
• unsuitable universal cleaners.

When

• 1–2 times per month;
• as an alternative to cleaning with GRES BRILL®.

How to Apply

• dilute 20–50 cc of GRES LINDO® in 5 L of water;
• apply with a microfibre cloth;
• do not rinse.

👉 Removes greasy residues and helps maintain a more uniform surface.

Deep Cleaning

When

Deep cleaning should be carried out as needed, depending on:

• household water hardness;
• the level of surface contamination;
• noticeable loss of shine.

As a general rule, it is recommended:

• once a year in heavily used areas such as kitchens, entrances and bathrooms;
• when the floor shows heavy streaking or an uneven appearance.

Product

GRES LINDO® + Blue Buffer Pad or MELAMINE BUFFER PAD
(mechanical action is essential for removing built-up surface films)

How to Apply

• dilute 170–250 cc of GRES LINDO® in 5 L of water;
• work on small areas at a time;
• leave to act for 4–5 minutes without allowing it to dry;
• scrub with a Blue Buffer Pad or MELAMINE BUFFER PAD;
• remove dirt and rinse with clean water.

👉 Removes built-up household films (limescale and greasy dirt) and restores the original shine.

When a Stronger Treatment Is Needed

If the floor remains very dull and does not improve after deep cleaning, the surface may contain:

• installation residues that were not properly removed;
• heavy contamination such as waxes or film-forming residues.

In these situations, a restoration treatment using POWER DET® + Blue Buffer Pad is required before resuming routine maintenance.

Technician’s Tip

With polished porcelain tiles, it is essential to avoid universal shine-enhancing cleaners, as they often leave residues that worsen streaking. The best strategy is to keep the surface free from limescale build-up with GRES BRILL® and periodically alternate it with a degreasing treatment using GRES LINDO®.

After a thorough deep cleaning, applying ANTISPORCO can help reduce dirt adhesion and make routine cleaning easier over time.
