Grease in the kitchen can sometimes stick around even though we have done a deep clean. If this happens to you, try this home-made remedy: mix one litre of water, lemon juice and a heaped tablespoon of baking soda. Spray on to the affected area: stoves, the extractor fan or inside the oven, and leave to act for 5 minutes. Then, simply remove with kitchen towel. The shine will return!
