Abstract

Outlines the current processes and materials used in the cleaning of historic stonework, giving a broad background to the situation as it stands at present. Discusses the reasons behind decisions to clean, highlighting aesthetics and damage monitoring. Provides an account of essential steps to take when cleaning historic masonry, and continues with an analysis of the inspection procedure, on‐site trials and specification. Explores available cleaning methods based on water, chemicals and abrasives, and describes the damage which can be caused by each with particular reference to limestone. Gives tips on the safe use of cleaning processes, as controlled by the Health and Safety at Work Act 1974, and suggests the use of small‐scale cleaning systems new to the general cleaning market in future.
