To keep drains running freely, pour a cup of soda crystals followed by boiling water down the plughole. This will help clear grease, soap scum and banish odours, too. Remember to wear rubber gloves to avoid skin irritation!
You can also slug vinegar and bicarbonate down the plug to dissolve any dirt, meanwhile, lemon juice can help remove strong smells. Finish off the job with lots of hot water.
