Sodium Percarbonate Powder 99% Purity - Oxygen Bleach, Hydrogen Peroxide Release Cleaner for Laundry, Dishwasher, Deodorizing & Stain Removal, Multi-Surface Use, Color-Safe (36 lbs)

I buy it for multiple purposes, mostly - for keeping my white/light clothes spotless. I use it with Hot regimen and it keeps everything white with no greyish shading. I also use it with boiling water to easily remove stains from multiple surfaces without rubbing - the steel sink, thermos, etc. - percarbonate sodium enters into a reaction when added to boil-hot water, the reaction visually looks like the one that baking soda+vinegar do - at the end, you receive crystal clear surfaces and all the removed junk is easily wiped or rinsed.

I use it in the laundry. I use it to clean my deck. I use it in my dishwasher. I even use it to clean the toilet.I love it!

The cartons are strong, secure and a good size to port product. Packaging was also strong and well managed.

Nothing I've used comes close to getting white and colored clothes cleaner and brighter.

They do weigh 9 lbs and not anything over, including the container they are in. But I still give 5 stars because the product works well, and ships well. Too bad it costs 3X the amount I paid 1 year before.No fragrance, additives, or fillers. Perfect for me.I bought the 4 pack to help save on cost per unit.
