oh you poor thing!! I remember having to do all that!!! I started out using Tide Free and Gentle and filled the same amt you did. I had to do about 7 or 8 full hot washes to get it all out!!!!
Now I use original Tide powder, and have FINALLY figured out that 3 tablespoons works perfectly for us. 2 was leaving a hint of stink and w/ 3, NO stink and no rash
It really is trial and error.
