A Opera Group srl  flooring or wall covering – whether natural, lapped, gloss or polished – is synonymous with beauty, strength and a long life.
These surfaces are low maintenance and only need be cleaned as described below.


First clean
The purpose of first-time cleaning is to remove any trace of cement or plaster used to close the joints.
The flooring/wall covering is normally cleaned once before use. 
This must be done before the flooring/wall covering is used.
Proceed as follows:
1. Sweep the floor/covering to remove the coarser dirt.
2. Dampen the surface with water so as to soak the joints, thereby protecting them from the corrosive action of the acid detergent (descaling product). 
3. Apply the detergent  in the concentration (water mixing ratio) indicated by the manufacturer using a manual or motorised brush. Avoid any contact between the acid detergent and the steel, aluminium, and natural marble components near the flooring/wall covering.
4. Leave the detergent on as long as needed, depending on the condition of the floor, then rub any stubborn dirt away (and scrape off residues of mortar, plaster, etc. …).
5. Rinse the flooring/covering with water and mop up the dirty water immediately (manually or with a washer/drier).
If the flooring/wall covering is cleaned for the first time after being used, it is important to use appropriate alkaline detergents (degreasing agents) before applying the acid detergent to remove any greasy or similar substance (see Routine Cleaning).
If necessary, you can repeat the first-time cleaning operations described above.

Polished, gloss and lapped surfaces
All polished surfaces tend to become more opaque with use. Because of its outstanding technical properties, with Opera Group products this process is slower than for any other natural material (marble, granite, stone, etc.). However, to protect the floor’s shine for as long as possible, it’s important to protect the entrance to the floored room, especially if it has an adjoining outdoor area, with a doormat that can keep as much dust or abrasive substances as possible off the floor.
A slight loss of shine after the first acid wash must be considered normal, as it is due to the removal of the abrasive residues used for processing the surface.

Here are a few detergents recommended for removing plaster residues: 
• Cement plaster joints – acid detergents (descaling products)
 Deterdek (Fila), Keranet (Mapei), Deltaplus (Kerakoll), or similar detergents (follow the manufacturer’s instructions).
• Epoxy plaster joints – alkaline detergents
Fuga-Soap Eco (Kerakoll), Kerapoxy Cleaner (Mapei), Tile Cleaner (Faber), CR10 (Fila), or similar detergents (follow the manufacturer’s instructions).

Routine cleaning
For everyday cleaning, all you have to do is wash the flooring/wall covering with water and normal neutral detergents suitable for ceramic surfaces (for wall coverings use a neutral gel detergent gel).
Make sure that the detergents do not contain waxy substances. The surfaces of Opera Group srl products are practically non-absorbent; therefore, the use of wax and/or silicone cleaners is not required. These should never be used, as they create a superficial film that changes the natural characteristics of porcelain stoneware.
Should there be any stubborn stain that cannot be removed by routine cleaning, use a more concentrated detergent and leave it on for long enough, then rub harder until the tiles are back to their original condition. Note that porcelain stoneware is resistant to any chemical, except (HF) hydrofluoric acid, which eats into any ceramic, so it must never be used.
Floors of public areas should be cleaned when the place is closed, so the floor will be dry when it reopens; otherwise, fence off the cleaned floor until perfectly dry.
For larger places, use a washer/drier to ensure perfect cleanliness and hygiene.

Special cleaning 
In the event of seizable and/or particularly stubborn stains, or for special cleaning of the entire surface, it is advisable to use specific detergents as indicated in the table below. It should also be emphasised that the removal of any type of stain is easier if it is removed while still fresh. For lapped or polished porcelain tiles, it is important to perform a preventive test before using detergent products.
