Cool, those are where I thought the clashes were, I just cannot make a word that fits and makes any sense lol.
10d "Wench scrubbing borders above mounted festoon" which I have assumed was ENC followed plus a word for mounted that starts with A, clashing with G from 18a, meaning festoon.
11d "Enticed female individual to go topless without fuss" which I think has a Y at the end clashing with N from 25a, but for the life of me cannot think what the answer is.
Also dont have 28 down about the sugar making waste.
