Do you have a spare bathroom in your home? I’m talking about one that is really unused for months at a time, and the toilet bowl gets black or brown streaks.
Here’s a useful tip that you can try to do to eliminate that ugly color. After the toilet bowl is cleaned the way you used to, pour in one or two cups of vinegar and DON’T flush. Isn’t it very easy? This will prevent that ugly discoloration. As an added tip, ensure you check infrequently used bathrooms for leaks in the plumbing.
