About us

Excellent product! It just took one spray to get rid of a patch of mould on the wall, without leaving a trace. The bathroom’s as good as new. Highly recommended!

Easy to apply, excellent self-polishing power and good end results. I’ve still got to test how it lasts over time.

Come tutti i prodotti Fila ottimo. Toglie le alghe anche senza sciacquare o passare stracci.
Consigliato da un posatore amico non lo cambio con nessun altro prodotto anche se all'apparenza sembra costoso (ne basta veramente poco quindi dura tantissimo). Non lascia aloni e soprattutto non appiccica come gli altri detersivi per pavimenti. Lo uso da tanto tempo e lo consiglio. Anche gli altri prodotti Fila sono unici!
Fila products always live up to expectations. I used it on an unpolished Serizzo marble surface that had absorbed months and months of dirt.
Fila products are always very high quality.
