The definition of maintenance is to maintain the appearance to it's original intended condition. If your building needs restoration, it has not been properly maintained.
It is nessesary to clean architectural stone surfaces just as it is glass or any other surface in order to avoid costly restoration procedures in the future. As well, it is important to chose the right combination of products to use. Use the charts to help you select the right combination of products for the project.
We strongly recommended that building owners and managers gently clean the exterior of their building's stone surfaces every one to two years in addition to the window cleaning process. This will help top prevent the need for restoration in the future especially if the stone surfaces have been protected with our protective treatments such as Leach Stop.
For cleaning stone surfaces that have been previously protected with Presto's Stone protective treatments such asLeach Stop or ElaSticone use Green-Kleen. For more aggressive cleaners for stone surfaces that are not protected with Presto's Stone protective treatments view TheStone Restore Series - a complete line of products to restore any stone surface.
