The Grade II-listed memorial, which is more than 120 years old, was carefully treated to protect the historic structure.
The memorial commemorates the men of Wallasey who lost their lives in the South African War between 1899 and 1902, while also recognising local residents who served during the conflict.
It was steam cleaned before being treated with an algicide to help protect it from future biological growth and weathering.
The Parks and Countryside Service is now developing a maintenance plan to help ensure the memorial, which features the figure of Britannia, remains in good condition throughout the year.
Further improvements are also planned, including the installation of a new brass plaque displaying the names of those who lost their lives in the South African War.
The memorial’s railings are set to be repainted by volunteers from the Central Park community group, with all works expected to be completed ahead of Remembrance Day in November.
