He also said it's tricky since you could remove color from the pavers. Any tips from the pros are welcome!

Acid wash is a loose term, sorry I should of been more attuned to that. I have heard of hot water being pressure blasted on heavy effloresent stains, also you could use a techni-seal product called effl. remover. It would be the best. Stay away from muriatic acid, even diluted it will remove some color from the brick. Years ago I ruined an entire brand new interlock driveway with muriatic acid. I replaced the whole thing including two walkways at my cost. uggghh.
