This polish is designed as a starter polish for new work or furniture that has just been stripped back. Restoring Polish will bring out the natural grain of the wood, feed the timber and give a good initial sheen. Restoring & New Timber Polish is excellent for restoring moisture to furniture that has become dry or faded and is effective on leather. The Dark Restoring Polish can be used on black or brown leather. Restoring & New Timber Polish is not recommended for constant use on French polished furniture or other similarly sealed surfaces, as it may be too 'greasy'.
