When cleanliness is not next to godliness | Letters

Your correspondent Jenny Brook is right (Letters, March 31), the article about cleaning was absurd (Have you washed your toothbrush lately? The surprising truth about how to really keep your house clean, March 30). The level of cleanliness described for some items is only necessary in an isolation room for a severely immunocompromised patient. So you’ve needlessly stoked the fears of many living with borderline OCD, not to mention the financial costs and time required to accomplish such a cleanup. Let’s have a more realistic view of housework.

As a biologist, I read this article with increasing concern, disbelief and disbelief. If we all do what is suggested, the environment will be destroyed and human immune systems will no longer exist.
