With the exception of the bathroom and kitchen, I clean on a seasonal basis. Once per season, I break out the suds and go on an OCD cleaning spree. Walls get washed, windows get cleaned, floors get scrubbed by hand, the Pledge cleaner gets used. Some say I get a psychotic gleam in my eye when this happens, so people generally stay OUT of my way when it happens.

All other times...messes really don't affect me. =/
