Do you have any pictures? Is the plant discolored or does it have small mushy areas? When you repotted it, how did the roots look? Is it floppy because the leaves are bent or because they are soft?

Make certain the plant crown has no water in it. I'm uncertain if I should advise you to remove the plant from the soil and air out or not, it all depends on what is the problem. Speculation: water was left in the crown when you were using the sprayer and the plant may have started to rot. This is only a guess at this point. Is there any other observation you can add?

I think Sans2014 is probably correct about the sprayer. Water in the crown of the plant is a death wish, in my opinion. If ever you are going to spray a Sans, hold it upside down so the "inside" of the plant is facing the sink, not the sprayer and spray lightly lightly lightly. But my suggestion would be -- simply wipe the leaves down to clean them.

It is hard to diagnose without a picture, but overall, your description sounds as if your plant has just had too much water, and too much fussing...but mostly too much water in the wrong places. A pic would really help people to help you save your plant.

If they're sideways, that's not a good sign. Is the plant mushy at the soil line? Are they floppy at the base of the leaves?

We really need pix to determine if it's beyond saving & if so, what to do for it.

As above. If the leaves are are wet and mushy - too wet.

If the leaves are long and spindly but not mushy, inadequate light at a guess. Or just old age.
