Clean TOCSY [1] is a spin-lock pulse sequence that reduces signals due to cross-relaxation (ROESY effect) while keeping signals arising due to scalar coupling (TOCSY effect).
As described in the original work [1], clean TOCSY is a modification of MLEV-17 mixing pulse sequence, where delays are inserted before and after the 180oy pulse.
MLEV-17 element (usually repeated back-to-back many times to add up to total mixing time):
Where black pulses are 90o and white - 180o.
Then clean TOCSY element is:
