after running under the rain for 30 minutes my white sneakers had a foul stench. I tried disinfectant and washing them with soap and water and lots of rubbing and sunlight to dry.
While that got rid of most of the smell, my white sneakers are now brownish, specially around the shoelaces.
I've never washed sneakers in the washing machine. Am I going to ruin them?
Shoeshiners are for "nice" shoes that use primarily "hard" materials for the outer layer that can be, well, shined. They don't typically take care of the inner parts where more standard fabrics are nor do they do sneakers.
Sneakers you can toss in the washer and call it a day
If they were as the OP describes, yes. Or whatever the equivalent to sneakers are. I just didn't know it was vastly different or that they could go in the washer without side effects as I've always failed.
