MAXTITE Sodium Percarbonate (4 lbs total - 2 pack of 2 lbs bottles) - 100% Pure - Solid Hydrogen Peroxide/Oxygenated Bleach - Multi-Use Cleaner for Home & Laundry, Resealable Child Resistant Cap

I use this to make laundry detergent!

Even removed old, heavily saturated, dried on blood. CRAZY wonderful stuff! Runs circles around a famous oxygen-powder cleaner we all know of. Be sure to use more powder if you have heavy staining or be sure to pre-soak. (I sometimes use an enzyme cleaner with this product but I am slowly learning that I don't need to.) The directions are NOT on the bottle, which I would take off a star for if it were not for the ultra effectiveness of this product. Good directions are available on Google AI

I add this to my laundry. I don't know that it makes whiters more white or helps stains come out any better than just my laundry soap, but I do think it helps the laundry smell fresher. It didn't work well as a paste for me to clean tile. I never could get it to a paste consistency, because it is more like little crystals than powder. But I dissolved some in hot water, sprayed on the grout, let it sit for twenty minutes and it whitened the grout pretty good.

Great product. One of my go too ingredients for cleaning.

I use 25 grams of this and 15 grams of plain old washing soda to run the clean cycle on my front loading HE washing machine. Cheap and effective. I may also use it to soak out some stains, but haven't tried that yet.
