I've been making my own detergent for ages... Might be time to revamp my recipe...
UPDATE!
So... I have been looking at the recipes and they all say to grate the soap. I didn't have a grater available to mess up with soap so I was chopping it really fine then mixing up the detergent. Very recently a grater came available. I grated my first batch today, and I gotta say, it works so much better than chopping. I have now put said grater into my laundry tote and will continue to use it, makes such a difference.
