Basically your leaves look like dog poo because you totally traumatized your plant. Power washing the leaves not once but twice. Spraying with soap. Repotting. Washing off all the soil from the roots. You've traumatized every part of this plant.
You should never assume that insects you see in your soil are pests. Some are beneficial, like beneficial mites, that eat other non-beneficial insects.
Washing all the soil off the roots is never a good idea. It damages your roots.
Blasting the leaves with water can damage them.
Repotting while all this is going on is a huge stress.
Those leaves probably will just wilt and die. Your plant now has to re-establish itself after basically the equivalent of getting hit by a truck.
You will most likely lose all your mature leaves and have to wait for your plant to re-establish, get rebooted, and start producing new leaves again from the center of the apical meristem
