Armourall on Flylines?

It s getting toward the end of the season and yesterday I was
fishing the other end of a Double taper line. I m hard on lines. And
the these "reetchy" sounds were coming off the rod as the line past
thru the guides. Almost like there was ice in the guides tho it was
50 degrees.

Figuring the line needed cleaning I put it in the bath tub today
and realized that it s past cleaning. Ingrained dirt, some checking
etc. Id like to get another month out of it and buy new line in the
Spring. I had some armoural and I liberally doused it in that. My fly
line dressing having leaked into my tackle bag last month....
I m not worried about ruining the line. Has anyone every been
desparate enough to have tried this "line restoration" method? Did it
work?
