Detergent Review :(

So I tried a load of laundry last night with the detergent I made. I took an old towel and rubbed ketchup and mustard into it as a test. At first glance when it came out of the laundry it looked clean...but upon further examination you could see faintly where the food was. And I'm pretty sure my normal store detergent would have been able to take care of it. So, I've been researching other recipes and user comments and am going to try another test without diluting the soap mixture. So basically I'm just going to try using it straight from the 5 gallon bucket...whereas before I used half mixture from my bucket and half water. I'll report back!
