Late Roman Bronze Coins

Hello, this is my first post on this forum
This is the coin:

MAXENTIUS AE25mm 6.70g follis
OBV: IMP C MAXENTIVS PF AVG; laureate head r.
REV: CONSERV â€" VRB SVE; Rome seated, head l. holding globe and scepter, inside hexastyle temple w/ wreath and knobs. H in left field.
EXE: RBS, Rome mint.
REF: RIC VI Rome 212, rarity-S. 308-310AD.

I bought it a couple wks ago. I have attached a before photo, an after photo and the tools of the trade.
Thank you.

It looks better...those red encrustations are some of the toughest.

I am not sure I want to tackle those.
It is quite a fair looking coin, a storybook example of that proverbial "better in hand"
