Polishing up on new household rules | Letters
Absent from your otherwise fascinating survey of towels and toilet brushes (Ditch your loo brush, 21 February) was any recognition of the weird psychology of cleanliness. Beyond a certain point, it becomes irrational. To get or follow instructions from an OCD cleaner is very problematic – just look at the extent of her daily routines (and the amount of water she uses for washing).
