Now this might not work for every stain but it's worked for me on coffee, tea and juice stains.
Cut a lemon in half. Squeeze out a little juice onto the stain then smash the lemon into the counter or refrigerator shelf and rub in circular motion. Let it sit for 30 seconds to 1 minute. Wipe clean.
This method also works for butcher blocks.
Lemon's are a natural cleaner. It's non-toxic so the kids can help clean. It smells great too!
