Just another option but not a magic wand....
If you, one string at a time, loosen them off till they are flapping about but still attached to the bass, then pull and snap em against the fret board really hard for about 30 sec maybe a minute.
Re-tune and viola. New strings. All the micro finger muck ingrained is forced out of the micro cracks.
Personally I just get replacement cheapo Rotos on. Might try the cheap Warwicks next as they seem to be along the same cheap end value string that I actually so far prefer.
If times are hard then any string cleaning is better than none but I find the results don't last that long whatever you do. Boiling them tends to weaken them and they snap easily. I used to do it a lot when younger though but mainly because coming in around the 80s it was a slap fest and new strings worked best.
[/quote]I do the loosening and snapping thing too and it actually works ! not for very long but it does work ,for some reason each time you do it the E string zing duration shortens at which point I give in and buy new strings 😊
