I found the BEST way to clean pleasers (including insoles)
I used 2.4% hydrogen peroxide cleaner, a towel, and a toothbrush. Spray generously all over (tape over or carefully avoid charger port on flashdance shoes). Let it sit for 5 minutes and then wipe the hard part of the shoe with the towel. Lastly, use the toothbrush to get in the creases on the sides where the straps meet the shoes and dead skin and dust collects. (You can also use a butter knife if the dirt is pushed way down in the crease). If you need them to dry quickly, use a blowdryer; Stay mindful of heat so you don’t melt or distort your shoes or catch them on fire.
Boom, they look brand new! I was starting to get grossed out putting them on, even though custies couldn’t see it in the dark ass club anyways. It absolutely helped me feel more polished and put together for work, though! I used a lemon scented cleaner, and my shoes smell faintly citrusy.
