Unfortunately, while this playpen is advertised as indoor and outdoor suitable, after just a week on our back deck, it's speckled in mildew. We tried spraying with vinegar and water, but no luck. I did report this hoping Wayfair or the manufacturer would have some recommendations for remedying and preventing moving forward, but my options were to accept 20% off which against $420+ (we ordered 2 and appended them together to create a larger space) was only an $85 refund, or they would replace it so long as we returned the existing playpens which we'd have had to pay for. 

So in a nutshell, great for indoors, bad for outdoors and shouldn't be advertised as such.
