White canvas shoes are a classic look that can be ruined by the appearance of yellowed stains. Yellowing occurs easily and may be caused by dirt, sweat, bleach or harsh cleaning chemicals. Keep yellow stains at bay with regular cleaning and a few easy laundering tips.
Remove the laces and wash them separately from your shoes in the washer and dryer. Throw them into a pillowcase and tie the case shut before washing to keep them together and tangle-free.
Fill a sink with lukewarm water, adding half a tablespoon of detergent to the running water to create suds. Dip a toothbrush into the soapy water and use it to scrub any heavily stained areas. Also, scrub dirt off of the soles.
Place the shoes into the washer set on warm water and a gentle, low-agitation cycle. Pour 1/2 cup of white vinegar into the washer during the rinse cycle. It will make whites even brighter and eliminate any lingering odors.
Dry the shoes in the dryer on low heat and check them every 30 minutes until dry.
