how to remove that stain that not even Sherlock Holmes could solve?
Ideally, with a damp cloth you can clean any accident on your dog's bed. But sometimes there are stains that are more stubborn and don't want to go away so easily.
For extreme cases: a touch of soap
If you come across a particularly stubborn stain, or you noticed it too late and it's been there for hours, don't worry. You can use a cloth dampened with soap diluted in plenty of water. However, make sure it is well diluted to avoid leaving solid soap residue on the fabric.
