Clare wears a uniform to school and also has to follow some other dress-code guidelines. One of which is that socks must be white or navy. I bought good-quality socks for her last year and they still fit her. But after one year on the mulch playground, the white ones weren't looking so white.
I had already soaked them in oxiclean without making much progress. Then after I saw this pin on pinterest and I wondered if the dish soap / hydrogen peroxide combination would work on dirty socks.
I soaked each of the socks in a 1 part Dawn to 2 parts hydrogen peroxide solution, scrubbing extra dirty spots with an old toothbrush dipped in baking soda as suggested. I let the damp socks sit for over an hour, then washed in hot water.
They were MUCH cleaner this time around!
We just gained back 3 pairs of white socks for 1st grade!
