How can you remove a stain around the top of your pool liner caused by an oil based tan ing product containing a bronzing agent?

To remove a stain from your pool liner caused by an oil-based tanning product, start by draining the pool to the level of the stain. Use a mixture of baking soda and water to create a paste, then gently scrub the stained area with a soft cloth or sponge. If the stain persists, a diluted solution of muriatic acid may be applied cautiously, but test a small area first to avoid damage. Always ensure proper safety measures are taken when handling chemicals and consult your pool liner manufacturer's guidelines.
