Help with cleaning problem please?
There was a dark area that I thought was soiled exactly like the one in the 2nd photo. I went through the 3 steps with the 7.7, 3.8 and 3.0. I then repeated the 3 steps but didn't let the bag dry in between which is probably where I went wrong. Now as you can see in the 1st photo the area is very dark, especially in the seam area and not looking good at all. I'm wondering if there is any way to correct my blunder.
