Characteristics: All wood naturally ages, darkens, changes color, and mellows over time primarily due to exposure to light. While this color change is imperceptible from day to day it may be significant over a longer period of time, and will vary based upon length and intensity of exposure to light.

On warranty replacement doors or drawers, we will not guarantee an exact color match. Imperfections such as checks (small surface splits), pitch pockets (small dark holes) or darker mineral streaks are natural and are not considered defects.

Care & Maintenance: Dust your furniture with a soft cloth and occasionally use a commercial wood cleaner that is not silicone based. Avoid placing furniture in direct sunlight or leaving it exposed to open windows. Avoid extreme changes in temperature, and keep furniture away from direct temperature change sources such as heaters and air conditioners. Never allow liquids, including standing water, to remain on furniture surface. Absorption causes wood to warp and finishes to peel and delaminate.

Your Ronbow Ceramic sink is manufactured to the highest possible standards. To maintain its condition, Ronbow suggests you follow these guidelines.

Most mineral deposits can be removed with non-abrasive soap and hot water followed by a clean water rinse. It is also recommended to dry the sink with a soft cloth as, over time, limescale can build up on the surface as a result of standing moisture.

Water quality can affect the appearance of your sink by leaving stains caused by a buildup of limescale or similar mineral deposits, especially in areas with hard water. Limescale readily absorbs staining agents such as tea, coffee, red wine, etc., leaving visible stains on the surface of the sink. Avoid having standing water in your sink by drying it when possible. A water softener may also reduce limescale buildup.

To remove limescale buildup, use a proprietary limescale removing product such as CLR® or Limelite®.

Alternatively, soak the problem areas in a solution of one part vinegar to three parts water. This will loosen the scale, allowing you to scrub it away with a non-abrasive pad and ceramic sink cleaner.

Spot Cleaning

IMPORTANT: Always spot test a cleaning product before using.

Oil, grease and fingerprints: These are generally removed with non-detergent soap and hot water, though a solvent may be required (such as white spirits or methylated spirits). Care must be taken to use the proper safety precautions.

Tea stains or vegetable juices: These are most likely stains clinging to mineral deposits such as limescale. See the information on mineral deposits below.

Mineral deposits and scaling: Generally caused by buildup of lime scale, remove by soaking in a solution of vinegar (three parts hot water to one part vinegar), then scrubbing the deposit with a non-abrasive pad. Alternatively, use a proprietary brand of limescale remover such as “CLR®”.

Care and Maintenance

Please use a damp, soft cloth with warm water and soap to clean your TechStone™ vanity top. If needed, apply common non-abrasive household cleaners. We recommend using cleaning products between pH 5-8, as products outside this range may damage the surface.


Please DO NOT use any cleaning products that contain any of the following chemicals: trichloroethane or methylene chloride (such as paint removers or strippers), hydrofluoric acid, liquid bluing or gentian violet. In addition, when cleaning your Techstone™ vanity top, DO NOT use abrasives, product with alkaline levels/pH greater than 8, or aggressive cleaning compounds like oven or grill cleaners.
