Posted by Your correspondent Jenny Brook is right (Letters, 31 March), the article about cleaning was absurd (Have you washed your toothbrush lately? The surprising truth about how to keep your home truly clean, 30 March). The level of cleanliness described for some items is necessary only in an isolation room for a severely immunocompromised patient. So you have needlessly stoked the anxiety of many living with borderline OCD, to say nothing of the financial expense and the time taken to achieve such cleaning. Let’s have a more realistic take on housework.

As a biologist, I read this article with rising alarm, incredulity and disbelief. If we all do as it suggested, the environment will be destroyed and human immune systems will be nonexistent.
