Hi! New here but signed up b/c I have a rare question that I can find little about through Google. Long story but a swim up bar was installed in my pool last summer. (It is removable.) It was constructed out of aluminum so it wouldn't be too heavy but it appears that the aluminum reacted with the chlorine in the pool water and crystalized. These crystals are stuck to the aluminum itself and also fell off into the water. When the pool bar was removed for winterization, water, dish soap, and a sponge actually got a good deal of it off b/c the crystals are not that hard. If I were to use the swim up bar again this year, do you know of any chemical I can use to clean the crystals off the aluminum thoroughly? And, any ideas of how I could prevent this from happening...? Like if I could treat it with something? My house is on the market so it would not be worth it to me to switch over to a treatment other than Chlorine.
