Clay Masonry Cleaning Manual

This manual covers the cleaning of clay masonry only and should not be applied to other masonry materials.

In addition to detailing cleaning methods, guidance is given on design and construction techniques to minimise staining and the need for subsequent cleaning.

Simple precautions will help avoid staining and disfigurement and are always preferable to later cleaning.

The methods detailed here are based on successful practices implemented over many years. However tests to determine the most effective technique should always be conducted before undertaking any cleaning or stain removal process.
