Cleaning a traverse / penjy while rope soloing

There's probably lots of info out there, but thought I'd ping the sofa patrol. 

What's the best way to get back to your bottom anchor on a penjy pitch - rap the haul line? If traverse, I understand you have to reverse aid it. 

Any tricks for efficiency cleaning traverses / penjys? Should you pull up the lead rope before fixing, or leave it in the bucket? 

If reversing a traverse, do you use a gri gri pulling downward from the "top" anchor (like a normal pitch) or the "Bottom" one (reverse leading?) ? 

for those waiting for a reply....well I found this excellent advice from P.t.P.P.: (RIP Marc-Andre)

On my solos I’ve always rapped the haul line.

Pete gives excellent advise in the linked thread, I don’t need to comment further. 

Yay, I don't have to answer. 

Puzzled re not rapping haul line? How the heck do you get back down a traversing and overhanging aid pitch? 

Mark's cleaning tip with the 5mm cord is definitely worth knowing.
