The urine alkali in the toilet bowl is very thin, it should not affect the use, if it is a little thicker and can't be flushed, you can use a rod to break it, add some toilet cleaners to soak for a while, and rinse with water.
Use vinegar or toilet cleaner, buy a toilet brush, add water to the toilet after going back and stir it a few times, don't add too much water, there will be bubbles, pour it on the urine stains, and it is easy to come down with a brush.
You can rub it with a Viss ball and soapy water, if it is too thick, you can only coat it with sulfuric acid, but you should be careful in the operation process.
It doesn't work, it's generally a matter of experience and tools. 90 dredgers can do it all.
