Looking for Guidance On Stubborn Water Line Tain Removal

[Darrindnelson]

Greetings. The plant in this vid https://youtube.com/shorts/cIPsWFln878 produces purple flowers daily that end up in the pool and depending upon wind direction end up gathering in 3 areas of the pool and appear to have stained the tile grout. I have tried chlorine, soft scrub, chlorox, tilex without success.

Any suggested magic tricks from those that may have solved this issue previously?

Thanks in advance.

Have you tried acid
Start with Ascorbic Acid (vitamin C) can be handled easily
Put some in a sock, wet it and rub

If that doesnt work, that is an organic stain so chlorine will remove it. It does take time though. Pool strength chlorine ( fresh) at 14-15 % is way stronger than chlorox (1.5-3%) so will act quicker but you may need several goes.
