these are sport and yoga asics leggings with a logo so worn off I peeled it off completely but there is still some visible, white-ish residue, some kind of adhesive I assume.

I found https://www.wikihow.com/Remove-Prints-from-Clothes but I don’t know if any of those solutions would work to completely remove the residue, plus, I’ve never done this, so asking for your advice.
