Hi there, I was called out on a similar situation and found that WEXA multi-purpose cleaner from Lithifin greatly helped in the appearance. However, it was patches caused by white adhesive so were not as bad as yours.
Try a tester patch first and see somewhere inconspicuous.
The product is available in most tile stores.
