Since the diapers have been sitting on shelves and potentially have been manipulated by other customers, we strongly recommend you wash them at least once (hot water cycle with small amount of detergent) before using them for the first time. (ottawaclothdiapers.com)
You can sanitize your bottles by hand (in hot, soapy water) or on the top rack of your dishwasher using a hot water cycle and detergent. (romper.com)
Pour the contents of the diaper pail in the washer and then select the hot water cycle. (thespruce.com)
