Any cheaper suggestions for putting some life back into a dry-ass rope, besides the more expensive Nik-wax type formulas out there?

Would you suggest Downey? Porque, es ternura que perdura, y perdura?

Fabric softener is really bad for rope, don't ever use it... (Email the manufacturer if you doubt me.) You should also never use fabric softener on fleece, Gortex and water proofed items for it kills the material.
I would just wash your rope in cold water using the gentle cycle "without soap." (Unless you can buy some "rope soap," cost $3.00 a pack at the local climbing shop.) Have your rope daisy chained so it won't get tangled or twisted during the wash. Afterwards, make sure it completely air dries away from direct sunlight.
As for retreating rope, Nikwax is the only retreating formula I will trust to bring back it's "Dry Rope" capabilities.

Here's a bit off the www:
Tests conducted in a study by Smith (1988) indicate that treatment with concentrated fabric softener reduced the strength of a new rope. Frank (1989) showed that certain ropes treated with dilute softener (per manufacturer’s recommendations) were stronger than the same rope without softening, after aging and washing. Frank reported that the likely mechanism at work explaining these results is that the fiber lubricants contained in new rope are lost with age, allowing the fibers to cut one another. Fabric softener replaces some of the lubricants. Excess softening leaves the rope effectively wet, with the corresponding loss in strength.
With this mechanism in mind, a further argument for treatment with fabric softener would be its effect on spring rate. Since a rope’s spring rate is determined by both nylon material properties and fiber weave, it is likely that fabric softener will help prevent stiffening due to loss of internal lubrication. In dynamic situations, the underlying physics shows that preserving the spring rate is as important as preserving its strength toward the goal of avoiding rope breakage. Probably more importantly, preserving the spring rate will avoid the higher climber loads in falls that would come from a rope that had become stiffer with age.

okay I'll listen,
man I don't want to wade through all that reading.
anastasia is right, email the company, but I don't have time and neither do they.
use a small amount of woolite. just go to the store and pay up the $3.00. Use the "chain stitch" and a bag. a bag (meshed) is used if you don't have the front load.
try to stick with H2O.
answer to question about battery acid. not quite, but don't forget chemical formulas starting with the letter is an acid.
read pg 54, "The outdoor knots book" by Soles, Clyde.
