I had a smell in wardrobe like mould but found nothing. Before I moved in evidently there was. Time to time the smell would be strong, but could not find anything. Tried several things including cloves but too strong. I googled "mouldy smell" and came across your product. Having used eucalyptus for many things thought okay I will give this combo a go. I am happy with smell so use every few days. My intention is to pull everything out of wardrobes and spray oil inside (rub on) and air for a couple of days. Will lift base and spray. I am hoping this will do trick. Have a container with holes that I will put some oil in to allow to flow through and smelll fresh. Helps with sleep so that is a bonus. Regards Joan
