Charming though they are, porcelain sinks are hard to clean because abrasive cleaners dull (and often scratch) porcelain surfaces. Take the gentle route and clean your sink with fresh lemon thyme tea. Place 4–5 bunches of fresh lemon thyme in a 12-litre metal bucket and fill it with boiling water. Steep for 5–6 hours and strain. Stop up your sink, pour in the tea, and let it sit overnight. When you drain it the next morning, you'll find a gleaming white sink that smells fresh as, well, a sprig of lemon thyme.
