Product maintenance

Cleaning products of unknown composition are not allowed.
If the effects of a cleaning agent are uncertain, please test it on an inconspicuous part of a frame.
Cleaning agents that cause unique and fast cleaning results without any effort might cause long term damages.
Regular cleaning of the outside surfaces, which is strongly recommended by Art Windows Services, prevent from long term settling of deposits consisted of industrial fumes, smoke, fling dust combined with rain and moisture. That mixture can impair windows and doors surfaces and change the appearance of decorative elements.
Gliding parts and movable hardware parts need to be greased once per year with acid-free oil or grease. Hardware parts are to be checked regularly for tight-fitting and wear and tear. Hardware shouldn’t come in contact with the care and cleaning agents which cause the corrosion.
Glass surfaces can be cleaned wet with cloth or sponge. Glass cleaners without scouring agents can be added to the water. Do not use metallic items such as steel wool or razor blades to remove persistent stains, drops of old paint or tar. Instead of them use acetone, petroleum ether or white spirit.

Alkaline cleaning lye, acids, cleaning agents containing fluoride are prohibited for cleaning the glass and wood surface.

To retain the correct functionality of windows and doors, gasket profiles need to be cleaned and greased twice a year. A suitable care product must retain the gasket pliable and protect it from losing flexibility and becoming brittle prematurely. Gaskets need to be cleaned mainly with water and if necessary with a drop of dishwashing liquid. Alkaline cleaning agents, mixtures of water and alcohol may be used for cleaning gaskets. Please be aware that moisture, ambient temperature and exposure time with the combination of high concentration of the cleaner may affect the condition of gaskets and cause damage. Avoid cleaners with chlorine and peroxides, oils, grease containing petrol which can cause discolouration. For uPVC surface, avoid the dissolving cleaning agents. Do not expose the cleaning surface to sunlight while cleaning.

Timber windows and doorsTimber Sash Windows Art Windows Services

Scouring, acidic and solvent cleaning products are not allowed to clean timber windows. Use mild products such as soapy water or water with a drop of dishwashing liquid, a cloth or sponge. Common products with small amounts of alcohol and ammonium chloride are suitable for glass. After cleaning, wipe the frames and profiles thoroughly with a dry and soft cloth. Do not use alcohol that applied too long may dissolve the paint on window and door frames.
External timber surfaces should be painted every 2 years. We recommend to monitor in particularly those parts which are exposed to strong sunlight, rain and wind to avoid the aggravation. Please, be aware that the proper ventilation of interior rooms affects the internal and external appearance of timber windows and doors favourably.

The intense ventilation of rooms in the building drying phase is crucial. This is the time when large amounts of moisture are released from wet internal plasters and cement floors. As a result of insufficient ventilation, water penetrates the weakest part of timber such as e.g. glazing rebates. Timber swells of moisture which results in further problems with opening and damage to the glue bond. Bubbles filled with the water may form on the exterior surface of frames. Sufficient ventilation helps to avoid damages of windows and doors.

Be aware of the following:

The high humidity in the room will cause swelling of the timber frames, and as a result, damage to the face of a frame may occur.

In the heated and well airing rooms, the timber windows and doors are less exposed to the risk of damage caused by the swelling frames.

To reduce the high humidity, airing must be repeated regularly. The windows should be left open for most of the time, especially during the construction works.

Aluminium frames

At least twice a year, the powder-coated aluminium surfaces need to be inspected with cleaning and conservation products to reduce corrosion impact and retain the appearance of all elements.

Cleaning surfaces are not allowed to be exposed to strong sunlight during cleaning. When cleaning, the temperature of the surface is to be less than 25°C.

An only soft cloth that not scratch the surface and clean water or with a small number of neutral cleaning agents (pH neutral between 5 and 8) is permitted. The cleaning product is to be not warmer than 25°C. Steam cleaning is prohibited.

When aluminium products have not been cleaned for a long time, the general cleaning and treatment with conservation agents are necessary. Conservation agents should only be applied after a successful pre-cleaning.

Avoid scouring agents and solvent which contain acidic and alkaline cleaning agents because they affect the surface. To remove old stains, especially greasy and smeary stains, use benzine or isopropyl alcohol (IPA). Do not leave them for a long time, just for a few minutes and rinse off with clear water.

Paraffin based cleaning and non-abrasive liquid products are good to remove resistant stains. Do not use heavy-duty products, tools with sharp edges like knives, razors, scrapers, steel wool, an abrasive cloth because they will damage the surface as well as nail polish remover and cellulose thinners.
