At Olson’s we get all kinds of questions! Recently, a customer was wondering if vinegar would hurt her onsite sewage treatment system. Absolutely not! Vinegar is made from natural sources like juices from fruits, vegetables, and grains. Vinegar is a great cleaning product and it doesn’t stop with your windows. For a clean toilet bowl, pour in a couple of cups of white vinegar and leave it overnight. The next day, swish with a toilet brush and flush. Or, sprinkle baking soda into the bowl, add a little vinegar, brush and flush.
