Sympathetic Limestone Cleaning Methods – Eco Soda blast cleaning service
Now you can benefit from one of the most advanced methods of revitalising any exterior stone including limestone - soda blasting. Specially graded sodium bicarbonate crystals are fired against the marble surface using low pressure compressed air. The crystals are much softer than limestone so when they come in contact with it, there is no scratching.
Soda blasting is particularly suited to the removal of:
- organic and lime based paints
- lime scale
- carbon soiling
- bird droppings
- algal blooms
Soda blasting works from the outside in. As the crystals impact the surface to be cleaned, they shatter. The energy from this shattering disrupts the surface of the contamination which is simply blown away in the stream of air and crystals. This removes successve layers of the contamination until the surface of the limestone is reached. Traditional methods rip the entire layer of contamination off in one fell swoop, will cause damage to the limestone surface.

Doff Cleaning systems - Limestone Statues and Architectural Features
During the 1990s, doff low pressure steam cleaning systems were developed for cleaning limestone and other stone cleaning tasks . Here at APT, our operatives, working with engineers, took this method to the next level, developing our proprietary 'Hot Box' low pressure high steam system. As well as being highly controllable, it is significantly labour-saving so you can benefit from quicker and lower cleaning costs. The Hot Box method of limestone cleaning has other advantages too:
- quick drying as the steam is superheated and the low volumes of water needed to produce that steam mean that very little water remains on the surface of the limestone after cleaning
- can be used in all seasons as no water droplets enter any pores or flaws in the limestone surface reducing the chances of freeze-thaw damage
- low surface pressure prevents damage to your limestone
- high temperatures kill the spores of mosses and algae meaning that no chemical inhibitors need to be used either before or after cleaning to retard re-growth
Cleaning Limestone Using a Poultice Cleaner
For very delicate sections or in locations that are sensitive to dust or steam, effective cleaning of limestone can be carried out using our latex poultice cleaner. Please see our poultice cleaning page for full details.
