First, cover the area underneath and around the appliance with dust sheets to protect flooring from dust and paint drips. Using a sponge, soap and water, clean the surface thoroughly. All wax, oil and grease should be removed.
Next, rub the appliance with an ammonia-based cleaner. Many household cleaning solutions contain ammonia (although you can use one-part water and one-part white vinegar instead). Mix the cleaner with water and sponge all over the surface, then dry it with a lint-free cloth or leave to air dry. Use a steel wool scourer to remove any remaining encrusted food and debris.
Now the appliance is clean and dry, you will need to sand it to provide a ‘key’ – this is a surface that paint will more readily adhere to. Choose a medium sandpaper and rub all over the appliance, wherever it will be painted. Dust the surface with a clean paintbrush, then sand a second time, with a finer sandpaper.
Carefully cover any areas you want to protect from paint with masking tape. This includes door handles and rubber seals. Press the tape down firmly to ensure no paint can creep underneath it.
