Are there really so many types of commercial oxygen-based bleach, and do you find it confusing to choose one? I also struggled with stains and odors on my child's clothes, so I actually tested and compared 16 popular oxygen-based bleaches.

In conclusion, the most important factor when choosing an oxygen-based bleach is its whitening power. How well it can remove wine stains and mud stains greatly affects the product's value. Among those I tested, Miyoshi Soap's "Kurashi no Oxygen-Based Bleach" performed overall the best, significantly whitening wine and mud stains even without soaking. It scored 4.76, and is affordably priced at 345 yen.

The next best is Saraya's arau Oxygen-Based Bleach. It features a natural aroma oil scent, and it was impressive how it could whiten wine stains without soaking. It scored 4.75, with a price of 427 yen. Kao's Wide Hitter PRO Antibacterial Liquid is also a candidate, but it’s a liquid type that’s strong against wine and mud stains, though it tends to be less effective on egg and foundation stains.

For those looking for powdered oxygen-based bleach, 100% sodium percarbonate products like Niwa Hisashi or Shabon-dama Soap are worth considering. Soaking them thoroughly can effectively remove wine and egg stains. If you want to use it for baby products, Pigeon’s additive-free Pure Baby Bleach is a safe choice.

Personally, I think having one commercially available oxygen-based bleach that can handle a wide range of everyday stains makes laundry much easier. However, foundation stains are difficult for any product to remove, so pre-application or direct treatment may be necessary in those cases.
