I ordered this plant and it arrived Monday 3/15/21. The roots were all bad and it has a couple of soft spots in the stem too. I would really like to save and reroot this guy. What should I do?

I have already removed the dead roots and rubbed off the mush in the the 2 rotten spots. I\'ve dunked it twice in Physan 20 (2tsp to 1gal), letting it sit for about 5 mins and I have it sitting on top of leca.

I kind of feel like I need to cut into it to remove the mushy vs just rubbing it off with my hand, but I\'m not sure. I rubbed some off on Monday and soaked in Physan 20 and then when I checked its condition on Wedneday it had softened some more, so I rubbed that off and then I re soaked in Physan 20.

I have the mushy spot circled in red in the photos, however because they are rotting the knots aren\'t as big now as they are in the pictures.

Best suggestions for saving this?
