In a previous post of mine I asked about solutions for cleaning my pool tile and got a few replies with such a great solution, I thought I'd post it separately so everyone finds out about it. The suggestion to help clean the suntan oils and "gunk" off of my pool tile was to simply use one of those Magic Erasers by Mr. Clean. I went to my local Wal-Mart and discovered that they sell a generic brand version of these "erasers" in a 4-pack. I used them to clean my tile yesterday and WOW what a great job it did. No need to buy all those fancy tile cleaning chemicals at the pool store!!! Be sure to stock up on these though, as they do dissolve during use - I used about 1.5 of them to finish my pool.
However, during the construction (pool is only been in operation for less than a month) it seems they did not do that great a job of cleaning up the grout, plaster and concrete - especially in the area of the boulder waterfall, and so I have some tiles that are still hazy due to all this extra covering of plaster, concrete and stuff. Even some of the grout lines are discolored. Some of this is due to the fact that the boulder waterfall guys broke a few tiles during that part of the construction and so the plaster crew did a last minute repair job on the tiles (not impressed with their repair). Can anyone recommend a method and/or product for removing that material and brightening up those tiles and grout? Is something like muriatic acid going to do the trick? I wasn't sure what you could safely use on an actively filled pool.
