Hello all pls see the picture attached and advice me pls. I do store my mugs in the cupboard above my oven and I have just noticed that the mugs are all steamed up after using the oven. I am wondering if there is anything I can do to prevent this from happening as I do not think it's hygienic. Perhaps something is not right in the installation as it was a DIY job 🤦🏽♀️
