Care & Maintenance
For our timber products:
Although our thermally-modified ash products are durable and naturally resistant to mold, mildew, and normal wear, proper maintenance and cleaning with OSMO Oil wood care products can help preserve their beautiful appearance.
The wood will naturally age to a silver/grey color over time when exposed to UV light. It is important to keep the surface clean and avoid spills and scratches, which can be blended with sanding if necessary. Following instructions and regular wood care will ensure long-lasting enjoyment and maintain the original coloration.
The thermally-modified ash color is not resistant to UV light. However, the silver/grey color does not affect its resistance to decay. To maintain or restore the original color, use OSMO Oil finishes and cleaners. Light sanding can also remove the silvering and restore the original wood tones, or OSMO Wood Reviver can be used for easier restoration.
Color differences between thermally-modified ash boards are common in natural wood products. Shape distortion is less common than in untreated wood but minor distortions can still occur. The color of the boards can change at different rates depending on UV exposure, rain, shade, climate, and sun orientation.
The thermally-modified ash may develop small stress cracks, typically not wider than 1116″ and without a length limit. Surface hairline cracks are natural and nothing to worry about. The surface of properly installed thermally-modified will shrink and swell faster than its core, resulting in these cracks during the shrinking process. Some boards may have more surface-checking due to growing conditions.
Applying OSMO Oil regularly can help minimize these cracks. Follow the oil manufacturer’s guidelines regarding application amount, temperature, and drying time, as they directly impact the oil’s performance and appearance of thermally-modified ash is highly stable but can still absorb and release moisture through the exposed end grain, which may lead to small cracks and end splits if it happens too quickly.
To minimize this, apply OSMO End Grain Sealing Wax on the ends of the boards before installation, taking care not to apply excess wax on the visible surface. Our thermally-modified ash is easy to clean with a mild detergent and brush should be used. Pressure washing is not necessary nor recommended. The natural result of our modification process is a rich brown color. Maintaining this color on an exterior application requires an oil based finish is applied. Over time, when left untreated, thermally-modified ash will age naturally to a stunning silver.
For our aluminum products:
Carefully remove any loose surface deposits with a wet sponge – do not scrub vigorously. Use a soft brush (non-abrasive) and a dilute solution of a mild detergent – do not use solvents. E.g. pH – neutral liquid hand dish-washing detergent in warm water to remove dust, salt and other deposits. Ensure you thoroughly rinse the surfaces with clean fresh water after cleaning to remove all residue or detergent films.
For our stainless steel products:
All stainless steel may become stained or discolored over time, impairing the overall look with this brown discoloration called tea staining.
Tea staining is discoloration of the surface of stainless steel by corrosion. It is a cosmetic issue only that does not affect the structural integrity or the lifetime of the materials.
For best results to maintain stainless steel products, wash with soap or mild detergent and warm water followed by rinsing with clean cold water, recommended on a weekly basis.
The appearance of the surface can be improved further if the washed surface is wiped dry.
For our plastic products:
To maintain the appearance, wash the area with soap or mild non-abrasive pH neutral detergent and fresh warm water followed by rinsing with clean cold water then simply wipe clean with a soft cloth.
For our premium plastic lumber products:
Scrub boards with soap and water solution using a soft sponge or plastic-bristled brush. You can use a soft-bristled toothbrush to clean spaces that are hard to reach. To remove surface dust, just wash furniture with cold, clear water. A pressure washer can be used on the lightest setting to deep clean your furniture.
It is not recommended to use more than 1,500psi. Keep the tip of the pressure washer at least 10-12 inches away from the furniture so it does not damage the lumber.
