Cleaning a modern grandfather clock is not much different to cleaning a traditional grandfather clock in terms of regular cleaning, but the products you use will vary. Older grandfather clocks made from wood normally require gentle and careful cleaning with specialized products. However, modern clocks which are made from metal or other sturdy materials can often just be dusted and cleaned along with the rest of your household furniture. If in doubt, speak to the supplier and ask what they recommend you do with the clock in terms of maintenance. Consider also that you'll need to clean the top of your clock which could be quite high depending on the size.
