Topic "How to clean an oiled walnut floor" a message from MacD

I have a customer that installed a Homerwood oiled soft scraped Walnut floor , then there was a lot of work still being done and a lot of wood dust and gyprock dust was grounded into the grain of the flooring . Does anuone have any suggestions how to clean the floor ?
The oil soap and refinisher from Woca didn't work .
