Quick car seat clean on my Nuna Revv! I used force of nature cleaning spray (40% off code Start40) Mirco rags and this mini powerful vacuum I keep in the truck & a hand held on I keep in the pantry for when I need it! I got my rag wet and sprayed on the rag and on certain heavier spots on the car seat everything lifted so nicely! I set out in sun to dry it all out! If you want to go further take covers off and wash on delicate, tumble try low heat (or air dry in sun!) **please remember to look at your cat start manual on how to wash and spot clean. I know all can be different. My manual doesn’t say to use the force of nature spray but we haven’t had an issue so I remind using it for spot cleaning! ** helpful link from a CPST on seat protectors, https://www.safeintheseat.com/post/are-car-seat-protectors-safe#:~:text=Maxi%2DCosi%3A%20Can%20use%20only,not%20recommended%20but%20not%20prohibited LTKBaby LTKBump LTKKids
