Re: Cleaning Swimming Pool Tile?
I've had an inground pool for around 20 years.I know exactly what you're up against.Most of the over the counter liquid or gel products at the local supply houses are only effective on surface residue.That three demensional calcified build up can be a real pain.I just cleaned mine this summer.The glazed tile will handle muratic acid without any visible etching.It's the grout between you want to be careful with.Here's what I did.Applied CLR to the tile,waited 10 minutes and then used a very sharp edged stainless steel scraper and painstakingly scraped each tile.Most of the bad buildup is at water level and above.Once done,I poured some straight strength muratic acid into a plastic container and used a 1" paint brush to carefully cover each tile surface at and above water line.Let it set for 5 minutes and vigorously rubbed down with a piece of stainless steel wool.Not perfect ,but the results were significant.It's an exhausting task,but I took several breaks and worked it in sections.Mine was the worse in the shallow end near the skimmer.
