Cleaning Limestone Surfaces

Limestone surfaces are a popular choice for renovations and improvements providing the luxurious expensive look of marble but an a more affordable old-world price. Most limestone is usually white or off-white in color with unique and naturally occurring patterns throughout the stone. 

Beautiful as they are, they come with a downside that they require more care than other stone types, such as granite. This is because compositionally, limestone is more porous and sensitive to acids attack. The porosity makes it more prone than other stains and discoloration. (We once were asked to seal a brand new set of limestone stairs after removing a coffee stain… it took 6 seal applications to finally seal the stone… and each day the property manager dropped a new cup of coffee as a test.) Once sealed it usually just takes another annual application to maintain, but the first application is a doosey. Once sealed spills are easily cleaned up without staining. 

Of course we still recommend cleaning them up immediately, as a sealer does not protect a surface from acid attack, so that orange juice is still going to leave a mark, it just won’t be a stain. Spill marks and drop marks on limestone result from spills, spritzes and drips of acidic liquids such as lemon, lime and orange juice. Wiping up these types of spills isn’t enough, as one needs to neutralize the acids least they leave a mark. MARBLELIFE Marble & Travertine Cleaner is formulated to do just that not just halting acid attack but surrounding and lifting the acid away from the surface so that its damaging effects are halted for ever more. Wiping acids with water simply dilutes them and reduces the effect.
