If you received hand me down gear with soft/cloth pieces-- like a car seat or swing-- from someone you know and trust, how did you clean it, or did you just glance over and make sure it looks clean enough?

I'm really lucky that I've been given a bunch of stuff like that from my sister, who I am sure kept the stuff clean, but a lot of it hasn't been used in 2 years. Not sure if I should be spot cleaning, or putting some things in the wash?

For plastic or wood toys, I figure I will wipe it down first with something like a Clorox wipe then rinse it in clean water? Also, how soon did you do that stuff? I'm due in just under 3 months-- stuff I clean now will be clean enough then, right?
