After being displaced by Eaton fire for almost two months, endless calls to insurance, dealing with cleaners, etc., we are back to our home. Now it's time to clean the pool. The cleaning company drained the pool to collect debris and ashes from the bottom. Unfortunately, pebbletec surface doesn't look good after being neglected for so long. The walls have a distinct green hue coming from algae while the bottom looks grey due to exposure to ashes. Powerwash doesn't seem to work to fully restore the original color. The cleaners offered acid wash, but I am hesitant to go this route. Is this the only option I have or there may be something else less drastic?
