The frame finish will have a little bit of input. Not too many polished frames these days but if it is you will want to use a polishing compound, either metal or automotive, your choice, to buff it up. Wax is always a good idea. More typical Ti frames are abrasively finished with nylon abrasive pads or some sort of soft blasting compound.
These just need soap/citrus cleanup and waxing is optional. If the frame is scratched nylon abrasive pads will usually clean it up and match the OEM scuffing fairly well. They come in several levels of 'grit' like sandpaper and a bit of experimentation may be needed. Ti can be anodized but I don't think this is very common now and these just need cleanup. Anodizing is not easily damaged or easily repaired as its color is hard to match.
