Whilst porcelain pavers are exceptionally resistant to staining and generally need just a wash with water or with a neutral detergent diluted with water, more stubborn stains may require some additional effort to be removed.
Try to avoid the use of abrasive products such as scouring pads, steel wool pads or products containing strong acids or alkalis.
With difficult stains and dirt, use a mild alkaline detergent, rinsing well with water after cleaning. For large surfaces, we recommend cleaning with commercial washer-dryer machines. Please bear in mind that some types of dirt (sand etc.) can have an abrasive effect on the surface of the pavers that is exacerbated with foot traffic, so such residues should be regularly removed by sweeping, blowing or vacuuming.
For particularly tough stains that resist removal with simple water/detergent cleaning procedures, we recommend using specialized cleaning products such as Fila Cleaner or FilaPS87. For supplies, see their store locator here ( ).
For rust stains, Fila also has a more intense acid based cleaning product called Deterdek which contains high concentrations of surfactants.

Resistant to the most common acids, such as vinegar, lemon juice, Cola (orthophosphoric acid) and hydrochloric acid.
These acids corrode the calcium in marble but leave no trace on ceramic surfaces. Not resistant to sulphuric acid damages.

The above recommendations are the result of research, laboratory tests and experience from the field. However, the suggested cleaning performance of materials can vary depending on the nature and location of the installation, the conditions of use, and the surface finish. As a general rule, pavers with higher anti-slip properties are more difficult to clean than smooth surfaces.
Please note that Kronos will not be liable for any damage arising from incorrect installation of the pavers, improper cleaning and maintenance procedures, or incorrect choice of materials for the intended use.
