Here is what you need as taken from the website:
- 1 4 lb 12 oz box Borax (2.15 kg or 76 oz) found in the detergent isle
- 1 4 lb box Arm & Hammer Baking Soda (1.81 kg) found in the cooking isle
- 1 box Arm & Hammer Super Washing Soda 55 oz (3 lb 7 oz) found in the detergent isle
- 3 bars of Fels-Naptha soap, found in the detergent isle (if you use Zote bars use 2 bars instead, Zote can be found at Home Depot)
- 2 small containers of Oxy Clean or store brand Oxy Clean (try to get about 3.5 lbs total (1.58 kg)) found in the detergent isle.
- (this is optional, I added it into mine because I have pretty messy kids and the cleaner the better)
- You should be able to find all of these items at your grocery store.
