If you want to get the rope clean, use Goop. If you want to eff around with all those wannabe methods, go for it. You'll eventually learn

Canola? Give me a break, Sean

. You'll have this result, imo...a rope that's still sticky where the pitch is bad before you begin, and slimy every where else.
Back in the days before I learned that neither polyester nor nylon ropes where damaged in the least by mild petrochemicals like the good hand/laundry cleaners like Goop contain, I tried all that organic crap, both on gear and on my body. Mayonnaise, hand lotion, CANOLA fer gad's sake. They all work only sort of...mostly not enough to be worth the effort, in my experience. Getting rid of the oily residue was nearly as big an issue as the pitch, more often than not.
But y'all can go ahead and figure all this out the hard way, just like I did...
BTW, if soap is needed, I have found Woolite to be easy on the rope finish, and easy to rinse out well.
