The blue bucket is what I am using to store my large batch of laundry soap. I have a smaller container I use on a daily basis and add to it as needed from the larger bucket.
Edited to add: homemade laundry soap can be used in HE washers. Instead of 1T-2T use half of a tablespoon per load. Here is the link to the recipe I use, she specifically states that this recipe can be used in HE washers.
