@huntersmommy101, take 1/2 cup of laundry detergent, 1/4 Cup baking soda and 1/2 cup of vinegar and mix it with hot water in your bath tub then put the pac n play mattress in and the pac n play on top and rotate it in about 30-45 minutes and you wont believe how dirty the water gets. I did this about a month ago and I was amazed then when youre done soaking it set it up outside in the sun to dry. hope this helps:)

baking soda, let it soak for an hour in the bath tub with water and baking soda

I know you can soak it in a bath tub with soap and let it sit over night drain the tub and extend it outside to dry

I seen on Pinterest to soak it in a bath with some sort of mixture. that's seems like the easiest way.

Vinegar and water

Lysol spray or wipes
