1. Use toilet cleaner, 84 disinfectant solution or dilute hydrochloric acid, because hydrochloric acid has the strongest ability to dissolve alkali. However, concentrated hydrochloric acid should not be used, because concentrated hydrochloric acid can corrode sewer pipes. If it's not very serious, just brush it vigorously with a brush. >>>More
Go to the supermarket to buy a clean toilet, buy a toilet brush, go back and add water to the toilet and stir it a few times, don't add too much water, there will be bubbles, pour it on the urine stains, and brush it with a brush It is easy to come down. That's how I do it all the time.
Go to a place that sells chemical reagents and buy a bottle of hydrochloric acid, about 1 liter. The concentration is about 25%, do not buy 37% concentrated hydrochloric acid. FIRST GO TO ABOUT 200ML TO SOAK IT, AND YOU CAN GET THROUGH IT WITH THE PIPE DREDGING MACHINE, ONCE DREDGED, THEN SOAK IT AGAIN UNTIL THE ALKALI IS FINALLY DISSOLVED. >>>More
Supermarkets have special toilet detergent that can be used to remove scale.
With urine alkali melting agent, this kind of thing has a very strong effect on removing urine alkali, not only the urine alkali in the toilet can be removed, even the pipe can also be removed, I have used it, the effect is very good, it is more time-consuming, it takes a long time to soak, and it should be carried out at night before going to bed, when not using the toilet.
