Soda crystals are great for all sorts of kitchen jobs, and they are economical to use.
# Clear slow plugholes. Pour a mug of soda crystals down the plughole and flush with hot water - they will effectively dissolve grease to prevent build-ups and smelly blockages. Avoid using on plated taps or fittings.
# Clean your washing machine. Once a month, pour 500g of soda crystals into the main drum and run through an empty load on the hottest wash. This works at ridding your machine of limescale and detergent build-up.
# Shine your silverware. Tips two cups of soda crystals into a foil-lined bowl, then half-fill the bowl with hot water to dissolve them. Submerge silverware in the solution, and leave to soak for 10 mins. Gently rub with a cloth to remove dirt, then buff dry. Do not use on aluminium or plated silver. Use rubber gloves to protect your hands.
Un-pong your bin. To clean your bin or recycling container, wash it with a solution of soda crystals following pack instructions.
