Our courtyard villa side walkway (done in Chattahoochee) is in full sun most of the day.
After about 2-1/2 years, it began to lose some of it's sparkle. It did not look bad, but I thought it was a good idea to have it resealed.
it's a pretty large area- the cost was $125.
We have, on a few occasions, had small patches of the white, hazy look you are describing. Sometimes, when the rains are heavy and the ground is too saturated for water to drain away, water collects in a small area for awhile. When the water drains away, mineral salts are left behind in that area- like mineral spots on your glassware.
Although they do not flush away using a hose, I have wiped these away easily- using a microfiber cloth saturated in a basin of vinegar water. No harder than wiping off a countertop. I pour plain water over it afterwards (to rinse the vinegar away) I have needed to do that twice so far on our walkway. Took just a few minutes…. there were only a few areas along the edge- where the walk borders a long planting bed. (this bed floods in heavy rain)
I keep some fairly large planter pots in our birdcage and rotate their location occasionally. I noticed a spot beneath one where minerals from fertilizer had drained. It too, WAS white and hazy. The vinegar treatment removed it- with no loss to the luster of the clear coat on the Chattahoochee rock beneath it.
