It is recommended to clean toys regularly, especially if they are used by children. It is advised to clean toys at least once a week, particularly if they are used regularly by young children or shared with other children. It is also important to clean toys after an illness or if they have come into contact with dirt. In most cases, it is sufficient to wash toys with water and a mild dish soap to ensure they remain clean and hygienic for children to play with. Never use harsh cleaning products to clean toys.
