A family member gave me her daughter's old bassinet. The bassinet is practically brand new but the only set back is that the white sheet has urine stains in it. I currently have the sheet soaking in hot water with a splash of bleach and deft detergent, the stain is fading but having gone away entirely and it's been soaking for about 10 minutes now. Do anybody know a way to get urine stains out of sheets ?
