5 Common Mistakes with Onyx
5 Common Mistakes with Onyx
Onyx is stunning but delicate, requiring careful handling and maintenance. Avoid these common pitfalls to keep its beauty intact.
Mistake #1
Using acidic cleaners
Why this is a problem
Onyx is primarily composed of calcium carbonate, which reacts with acids. Acidic cleaners cause etching, dulling the surface by dissolving the stone's calcium carbonate.
How to fix it
Light etches can be gently polished with Lithofin MN Polishing Cream. Severe etching may require professional refinishing.
Prevention
Only use pH-neutral cleaners like Lithofin MN Wash & Clean for regular maintenance.
Mistake #2
Failing to seal after installation
Why this is a problem
Onyx's medium porosity allows it to absorb liquids, leading to stains. Without sealing, substances like wine or oil can penetrate and discolor the stone.
How to fix it
Apply Lithofin MN Stain-Stop to protect against stains. For existing stains, use Lithofin Oil-Ex to draw out oil-based discolorations.
Prevention
Seal onyx immediately after installation with Lithofin MN Stain-Stop or MN Stain-Stop ECO to prevent absorption.
Mistake #3
Exposing to temperature shocks
Why this is a problem
Onyx is sensitive to rapid temperature changes, which can cause cracking or structural damage due to thermal expansion and contraction.
How to fix it
Repair cracks with professional stone adhesives. Severe damage may require stone replacement.
Prevention
Avoid placing hot items directly on the surface and protect from cold drafts, especially on thin panels.
Mistake #4
Neglecting to protect from sunlight
Why this is a problem
Exposure to direct sunlight can cause onyx, especially green and red varieties, to fade over time due to UV radiation breaking down the stone's pigments.
How to fix it
Use Lithofin MN Colour Intensifier to enhance and restore faded colors.
Prevention
Install UV-filtering window films or use curtains to shield onyx from direct sunlight.
Mistake #5
Using abrasive cleaning tools
Why this is a problem
Onyx's softness (hardness of 3) makes it susceptible to scratches from abrasive tools, which can mar its polished finish.
How to fix it
Light scratches can be polished out with Lithofin MN Polishing Cream. Deep scratches may need professional refinishing.
Prevention
Use soft cloths or non-abrasive pads for cleaning to maintain the stone's surface integrity.
