I did not know all of these! I, too, am having to learn these supposedly easy grown-up things on an as-needed basis, so this list is completely useful to me, too.

Though I did see once on tv that another way to clean venetian blinds if you're not thrilled about using a hose is to immerse them in a cleaning solution in a tub or something, let 'em soak for a while and scrub over them with a cloth to help get up any stubborn spots. This method can also be used for things like dirty mesh or yellowed lace.
