Trajan AE Sestertius - Help to Clean this Coin

honestly? A brass wire brush can help but not much . I have used that on bronze , copper and with surprising success.

olive oil and solvents don't really work.

BRONZE COINS: As a rule, bronze should be cleaned mechanically (i.e.. with brushes, and toothpicks), and silver should be cleaned chemically (i.e., with ammonia). ... Use a small denture brush or soft brass bristle brush and brush them gently. FORVM sells a good brass brush made just for this purpose.

 

Sincerely saying, I don't know what is either SIMONIZE neither brass wire brush. My methods are very different.

Silver cleaning approaches and bronze cleaning approaches are very different.
