The detergent should not be very effective, I use the toilet cleaner, the kind that makes the toilet, sprinkle it on the tiles, wait about five minutes and then use the mop to mop it, I feel that it works. View the original post
It is estimated that it is a trace left by scale, which is alkaline and can be treated with acidic detergents, or it can be replaced by hydrochloric acid, battery stock solution, etc. Be careful not to hurt your hands, though, and it's best to wear gloves.
Mix hydrochloric acid or phosphoric acid solution with water in a ratio of 1:5, spray the mixed water on it (you can also bring rubber gloves and wipe with a rag dipped in water), and wipe it several times. >>>More
