BIZ 37.5 oz Powder Carton (8 per case

good quality

Biz has been around for at least 50 years, but after trying Zout, lemon juice, apple cider vinegar and Spray & Wash, it's the only product that removed the sweat stains off my colored tops. I wish I'd taken 'before' photos as proof. Very effective! Note* I haven't tried it on set-in stains when the tops have been heat dried. The tops I used had only been air dried. But it's worth a try!

The product is effective but note that you will only get one box and the "(8 per case" description is not what you'll get. Though the seller's customer service is very responsive, they should modify their posting so as not to be confusing.

I love this stuff. It makes oxygen bleach look like useless powder. I wish I could add it to Subscribe + Save but it's always out. Perfect for towels, yucky clothes from my husband's fishing trip. I just toss in before adding clothes (as a booster) and it makes everything come out smell-free. Grease stains are still 50/50 but i am very pleased overall.

This is a great product. It removes many stains that other things won’t, especially if you pre-. But you should know that it is overpriced at Amazon. If you can find it locally, buy it locally.
