Both my little ones are in cloth diapers, and I’ve found vinegar to be very effective in removing stains and odors.
I add the vinegar to the rinse cycle (fabric softener compartment), and it also washes out the detergent better, preventing diaper rash and making the cloth softer. My 5-month old is wearing stain-free diapers that I made for his big sister. It works on the rest of the laundry, too (but not on dark colors because it can cause them to run).
