The only way to clean the inlet valves is by removing the inlet manifold and walnut blasting or soaking and scraping out the dirt.

It WILL come back. Minimise this by using premium fuel (V-power), using good oil (Millers CFS Nanodrive 5w40 for example) and ensuring air filters are clean.
WMI will also help prevent build up
