Oxyclean ?

Sorry if this isn’t the right group but I’m looking for real life tips, not YouTube paid promotions 😂 does anyone really like it? My husband works outside and I let his work clothes soak in oxyclean for an hour and then washed them and added some oxyclean to the load also.. and they look a little better but definitely nothing to write home about lol. Do you let clothes soak for the whole 6 hours?? Or is it really just a mediocre product? Thanks.
