Recently found this at my local Menard’s for $8.99. A mild acid based product…it worked pretty well to take white haze off of pavers. But as @florida_condo_cleani mentioned, Muratic would be higher strength, more aggressive acid. If i’m not mistaken. One of those products should do the trick
I didn’t dilute this product, just pre-wet the area, then applied it with a pump sprayer, scrubbed the pavers with a stiff bristle brush, let it dwell for 10-15 min while misting it a couple times, then rinse.
Edit: I also compared this to good old white distilled vinegar, and honestly the vinegar did a great job to remove the white haze as well. I think the Akona product was a little better, but I might be biased because I spent $8.99 on the Akona and $2.69 on the white distilled vinegar 
Worth a shot for those calcium deposits
