Medhātithi’s commentary (manubhāṣya):
‘Non-metallic—His vessels for carrying food or water shall not be made of gold or other metals.

‘Free from holes’— not having any holes etc.,

These are cleansed, like the sacrificial vessels, by means of water alone; but only when they are not stained; if there are stained, these should be removed by the use of other (cleaning) substances also. (53)
