Limestone retaining walls are popular fixtures for homes in Australia because the material is available in abundance, especially in the western part of the nation. But constant exposure to sun, rain and other weather elements can cause dirt, grime and moss to form on the walls over time. Pressure cleaning is a good way to get rid of dirt from limestone retaining walls, but make sure you consider these factors for the best results.
Avoid Cleaning Decorative Fixtures On Walls With A Pressure Washer
Pressure cleaning is best undertaken against the sturdier part of your limestone retaining walls because rough stone is tough enough to handle the pressure, provided you don't go all guns blazing. Avoid using the high pressure cleaner on textured and decorative fixtures because you could end up destroying them with the pressure. Thin textured elements will buckle and flake under the pressure, which will ruin the aesthetic appearance of your limestone retaining walls.
Rinse With Plain Water And Clean With Neutral Limestone Cleaner
Rinse down your limestone retaining walls using a pressure washer. Pressure cleaning is ideal when you need to remove stubborn stains and grime from the walls. The high force makes it easier to lift these marks from the surface. Keep in mind that you will need to employ the machine at a low setting to avoid any damage. Once you finish rinsing off the walls with plain water, apply neutral limestone cleaner to the wall surface. The cleaner must be suitable for limestone, so make sure that it contains no acidic ingredients because any acid will gouge the limestone. Acidic cleaners are usually made from citrus, ammonia or vinegar bases. Limestone-suitable cleaners are available at retail or home improvement stores.
Use Only Soft Bristled Brushes For Cleaning Limestone
Once you apply limestone suitable cleaners, you will need to gently rub the dirt off the wall surface. Make sure you use only soft bristled brushes for removing dirt from the surface because hard and abrasive bristles can end up etching the limestone. Always work in small segments and wash the area completely before proceeding with your retaining wall cleaning task. This will prevent dirty soap water from drying and leaving streaks on the limestone surface. Once you finish cleaning limestone with the brush, use the pressure water to rinse the wall completely before letting it dry.
