pH of Strong Bases

Part of the Acids and Bases section of Coddy's Chemistry journey. Lesson 14 of 30.

Strong base: [OH⁻] first, then [H₃O⁺] = 10⁻¹⁴ / [OH⁻], then the pH. 0.001 M NaOH: pH 11.

Two OH⁻ a unit (Ca(OH)₂, Ba(OH)₂): double first. 0.05 M Ba(OH)₂: [OH⁻] = 0.1 M, pH 13.

Challenge

An oven cleaner is diluted until it is $0.001\ \mathrm{M}$ NaOH. What is [OH⁻] in it, and what is its pH?
