I have a slate project also with etching. At some point the customer's father used muratic acid to clean off efflorescence. I have tried using a color enhancer to solve the problem but the color enhancer only highlights the etched areas.
Suggest you test this first an area prior to taking the job. It’s always bet to test.

Do you think I could get away with cleaning and color enhance only ?

yes, it could be acid burn and it could be a coating. The alkaline cleaner should remove both.

Can anyone ID this problem? Customer sent this to me and before I go running out to the house, I thought Id get some feedback.
