Stroller, car seat & play mat in like-new condition. Is it necessary to steam clean by professional?

Hi mummies, I was given the above items which are pretty new and have no stains. I came across Pramwash and thought it would be good to take the lite package for each item ($29). But upon reading thoroughly, I realised first time customers have to take the Basic X package ($67) @.@ I would like to ask how do you clean your baby items? Is it necessary to send them for steam cleaning? Or if you do the steam clean yourself, what brand of steamer do you recommend? Thank you! #1stimemom #firstbaby
