Hello, I'm new to the site and I'm after some advise please? I bought a Quinny Zapp Xtra 2 second hand and she said the cover had been removed and washed (it handn't) so I took it off washed it by hand and hung it on the line to dry, and now there's water stains on the seat bit :( I'm blaming my husband for not rinsing it properly lol, should I rewash it in the hope that next time it'll not happen or have I ruined it... Any advise would be much appreciated thanks
