It might surprise you to hear I have never used a dishwasher. That means any stubborn and annoying stains on my dishes are ones I tackle by hand. For most of my life, I've used standard sponges and an overnight soak in the sink, plus elbow grease to get the job done.
That was until I learned in Japanese culture, the answer to such struggles is the Tawashi curved brush: a special cleaning tool unlike anything else you're likely to come across in the average kitchen.
