I recently replaced my pool tile with slightly textured ceramic tile and dark grey grout about 1 months ago. Also resurfaced the pool with Stone Scape. The pool is beautiful and I'm very happy with the workmanship. However, now I am noticing an unsightly white haze (efflorescence?) on my dark grey grout lines. Water chemistry is on target. White haze only appears when the grout is dry--making grout lines appear white (dark grey color is restored when wet). I've tried vinegar/water, rinsing with hose, drying with a towel, Muratic acid but NOTHING WORKED. After spending several thousand $$$ on this work, I would expect the grout to look MUCH better. Is there a way to permanently restore the rich dark grey grout lines (without, of course, removing and replacing)?

Use your favorite search engine and ask "grout looks different wet versus dry"?
Yeah my issue isn’t that it looks lighter but looks like there is calcium build up or effervescence in certain spots. Make sure if the installer made a mistake or something else
