Clean flip flops with curtain detergent
Flip-flops that look worn after the summer and leave "black footprints" are super clean when you put them in a bucket of warm water and just put in detergents for curtains.
Just put flip-flops in the bucket in the morning (cover them if necessary, as they usually swim up) and get them out of the bucket after work. Brush off briefly with a small hand brush and the pines shine like new for the coming season!
I tried it myself and I'm really excited!
