"The toilet in my basement hardly gets used. How do I keep the bowl from getting black streaks? -- Lois Anderson, Dearborn Heights, MI You are going to love this hint: After you clean the bowl, pour in 1 to 2 cups of vinegar and don&amp;#039;t flush. It&amp;#039;s that easy. This should prevent discoloration. Check infrequently used bathrooms at least weekly to make sure the plumbing isn&amp;#039;t leaking.
