I'm not sure if this is what you want, but when you upload file into document library, setting custom properties invokes item updating events. You should be able to write your event receiver for ItemUpdated (or ItemUpdating) event and clear properties you want here.

So the code can look something like this:

public virtual void ItemUpdated(SPItemEventProperties properties, bool isCheckIn)
{
    try
    {
        this.EventFiringEnabled = false;

        SPListItem listItem = properties.ListItem;

        //clear value in your custom column
        listItem["myCustomColumnName"] = null;

        listItem.Update(); //or listItem.SystemUpdate()
    }
    finally
    {
        this,EventFiringEnabled = true;
    }
}

I haven't tested this code, so let me know if you have any issues when running it.
