Roman Metal Armour-Polished or Dull?

[Dan Diffendale]

"..Their arms shall be kept burnished, their implements bright, and their boots stout..."
Historia Augusta, The Life of Aurelian; Part 1, p207

I'd like to see the original latin to check on 'burnished'.

arma tersa sint, ferramenta samiata, calciamenta fortia
from tergere, to rub off, wipe off, wipe dry, wipe clean, cleanse

It applies to arms also at Livy 26, 51, 4, secundo die arma curare et tergere ante tentoria iussi, while Scipio is besieging Carthage, "he ordered them to review and scour their arms before their respective tents" in the Baker's 1823 translation.
