How to clean quartz<br>Rinse the quartz off with a power washer. If you have a large amount of quartz with a heavy amount of mud or dirt on it, you can try to rinse it off with a power washer. Set your quartz on the ground (preferably on concrete or asphalt) and rinse off the dirt.
A power washer is practical if you need to remove a bit of dirt.
The text says "If you have a large amount of quartz with a heavy amount of mud or dirt on it, you can try to rinse it off with a power washer." - a heavy amount is not the same as a bit; the model missed this detail.
