I just cleaned mine before I moved by lightly spraying with the sprayer on my kitchen faucet in sink and they cleaned them up nicely. Mine are all leaves and hearty floral, nothing that looks delicate. Laid them out on the towel to dry. Then I went back with a wet paper towel and a little bit of dishwater soap to get the small sections the water missed. There use to be product sold at Costco but it was a tad expensive for my budget. Mine are outside plants since I wasn't born with a green thumb!!
