If it is light etching, just take 400 sand paper and 5X. You should have no problem matching the finish. If 400 does not work, drop down to 250 then 400. If concern about matching the finish, try a test spot!

I am having some trouble with a job I am currently on. Part of this job involves Botticino walls. (About 2000 square feet) There is some type of streaking from something a previous contractor put on it. I have no idea what it is. There are only about 10 spots on the walls where this is present but the customer is not happy and it needs to be removed. I have tried powder polishing to remove them (MB12 and 5 X) with no success.
I am wondering if I should try honing the stones where this is occurring,and then repolishing, but I am afraid that the new  finish on these stones, while removing the streaks, will be different from the finish on the rest of the walls. Also, any thoughts on if honing is an option, could I do it dry ????
 Any suggestions appreciated.
