If it's not very serious, scrub it with vinegar a few more times, and that's fine. The way to spend money: use a special floor cleaner that can not be completely removed, and then use this method: use more than 800 water sandpaper to polish the mark with water, and then wipe it clean with a soft cloth, which will not hurt the bricks.

Try the toilet cleaner, spray it on the dirty area and use the broom to clean it after a few minutes.
Dilute it with edible vinegar with a little water, the concentration of the dilution depends on the degree of scale in the pot, and then boil it on the fire for 1 hour, put it on the floor to cool naturally, and then gently wipe it off with a dish towel, this method is very useful, there is no sour taste of vinegar after washing, I have used it myself.
In this case, it is very likely that it will break and leak, and it is relatively likely, but no one can predict it.
Put the rubber mat in the toilet, put it in the bathroom, or in the sink, rinse it with water, then spray the toilet cleaner with a watering can, brush it with a brush, and rinse it with water!
Because it is a tile floor, it can be scraped directly with a metal blade.
The glass glue in the bathroom will dry in about 24 hours. >>>More
