Maintaining and Caring for your Stone Sinks


There are a few simple and easy steps to follow in order to maintain your natural stone sink and keep it in a 'like new' condition:

After each use, give your sink a quick rinse with clean water just to be sure you’re not leaving behind any chemicals or harmful residues that could build up on the surface or etch into the stone and regularly give your stone sink a cleaning with a very mild soap and dry it with a soft, clean cloth.

Re-apply a protective sealant to your sink on an 'as needed' basis... but at least once every 18 to 24 months, depending on its use.   

There's one more important note...   All types of abrasive products and acid-based cleaners will scratch the surface of your sink and may cause irreparable damage.  Always, always, always avoid using abrasive and/or acid-based products on your natural stone sink and tub. 

Hard Water Areas

If you live in a hard water area, where the mineral content in your water is high, it's especially important to dry your stone sinks with a soft cloth after each use.   

When 'hard' water is left to stand, minerals in the water can build up and may begin to form deposits on your sink.  Once that happens, the residue may be difficult to clean and, in extreme cases, may actually stain the stone.  If this should that happen,  you'll most likely have to use a specially formulated poultice to 'reverse' the stain, or contact a qualified, 'natural stone' specialist to assist with its removal. 

Protective Sealant - To Seal or Not To Seal Natural Stone

There is some debate amongst stone professionals as to whether or not natural stone products ever need to be sealed. 

On one side of the debate are those who believe that natural stone is best left unsealed... in its natural state.  Their argument is founded in the fact that natural stone can sometimes have any variety of unknown elements embedded in the stone.  Their concern is that artificial sealants have the potential to cause an irreversible discoloration of the stone should there be some kind of a reaction when these elements and the sealant come in contact with one another.  

They are confident that because stone was formed over thousands of years... in the harshest of elements... it can safely withstand all types of use.  Furthermore, they argue, some sealants actually change the stone's natural colour and give it more of an artificial look. 

The argument for sealing natural stone rests on the idea that today's world is filled with many harsh cleansers, chemical concoctions and caustic substances .  Most of these items have the potential to etch into the stone and/or damage the surface.  For those on this side of the debate, sealing natural stone is the first line of defence against these potentially harmful elements.  

Definitely each argument has merit and the 'seal or no seal' decision is something you yourself will have to decide. 

Our stone sinks are pre-sealed with a penetrating sealant at manufacture.  The sealant is designed to prevent your sink from absorbing items that may cause staining during normal daily use.  The sealant does, however, loose its effectiveness over time and needs to be reapplied.

You're probably wondering how often should you apply a new coat of sealant. 

The answer is on an 'as needed' basis. 

A good rule of thumb is about once every 15 months, however a simple test will reveal if your sink or bath tub needs to be resealed more or less frequently. 

If you notice that the water continues to 'bead up' on the surface or immediately soaks into the stone.  If it no longer 'beads up' on the surface, it's time to consider resealing your sink. 

Applying the sealant is a very easy and quick process.  Just be sure to purchase a high quality penetrating sealer that is appropriate to Limestone sinks.
