These unsightly spots were partially hidden beneath the edge of a sofa.
I'm unsure what they were originally. They appeared shortly after having some guests over, for a holiday dinner (kids all went to the living room to play Monopoly while adults lingered at the table). It could be sparkling apple cider, but I'm not at all certain. Anyways, I had tried liquid dish detergent to no avail. My intent had always been to buy a commercial carpet spot and stain remover.
One day, last week, I thought to try some ordinary, drugstore 3% solution, hydrogen peroxide. I dribbled tiny amounts from the cap of the bottle, onto each spot. I very gently rubbed with a cotton t-shirt rag. And then reapplied the hydrogen peroxide a couple more times. I only used about 2 tablespoons of the hydrogen peroxide, in total.
When it appeared that the spots were sufficiently removed, I blotted the area with a paper napkin.
Spots are gone. Carpet looks great, again. It's hard to believe that this carpeting is now 21 years old.
We've very recently rearranged some furniture in the living room, and this area of the carpet was in full view. Taking care of those spots is one more item to check off of my list.
