Once you’ve rinsed your basin with cool water, mix vinegar with some salt and 0-10% acid. Do this as recommended by the manufacturer. Then pour it into the bowl and leave it for a few minutes before flushing. This will dissolve any organic matter like urine or dirt.

Chemical toilet cleaning products are not necessary if you have some good ‘ole vinegar on hand. Just mix 1/3 water, 1/3 vinegar, and 1/3 of whatever acid you have. Citrus juice and balsamic vinegar work just fine. Apply the mixture to the bowl with a sponge or rag, then let stand for 10 minutes.
