Tiled floor of shower is covered in rust. How can it be removed?

Shower wasn't used for ten years. House is being rehabbed and the floor is covered with a buildup of rust from water leaks. Tried everything, but can not remove the majority of it. Need help. Tried hydrogen chloride and salt, baking soda and vinegar, CLR, etc. Thank you

    I'm guessing that you've used an actual rust remover? If that didn'the work, you might try painting it with an exterior, patio paint. The surface would be slick, when wet, so I'd add no-slip decals, as well. Frankly, if it were mine, I'd put up a cute shower curtain, and call it a day. LOL

    The Dollar Tree carries a product called Totally Awesome Rust, Calcium and Lime remover. It works quite well and is only a buck:) Pour or spray it on, let it sit for about an hour and rinse well. That should do it.

    Rust can be removed with an acid, so vinegar, lemon juice and so on are good home remedies. However, baking soda neutralizes the acid making it less effective. Vinegar can take up to 30 minutes to remove rust and is less effective on vertical surfaces, so respraying is necessary.
    There are commercial rust removers, but you need to read the instructions. Some only work on metal. Some remove rust from clothing but can damage tile. Magica Rust Remover may work for you and should be available from Walmart. Good luck.

    Take the tiles out and replace them. If you have gone through all of those recipes and probably put in hours of labor intensive work, it would be more straight forward to replace.
