How can I take care of my Ludi products?

Foam-based products are machine washable (cold). A bathtub would do the job nicely as well!
The mattresses in our bedding products (portable beds, pop-up cradles, portable tents, etc.) are machine washable. All of our polyester, PVC, and plastic products can be cleaned with a damp cloth.
The calendars can be dry-cleaned.
