Removing pollen: how to effectively remove pollen from surfaces

What are pollen and why do they adhere

Pollen are the male reproductive cells of seed plants packed in a grain surrounded by sporopollenin one of the most resistant organic substances in nature. That outer layer contains proteins lipids and carbohydrates forming the organic basis of the pollen grain. Pollen grains are electrically charged and have a sticky outer layer designed to attach to surfaces for pollination. That adhesiveness makes removing pollen more challenging than removing regular dust. More on the basic mechanism of ozone water: ozonewater.

Pollen as organic contamination: the chemical basis

The organic composition of pollen is the basis for the effectiveness of ozone water in removing them. The proteins lipids and carbohydrates in the pollen grain are organic compounds that react to the oxidation mechanism of dissolved ozone. The ozone reacts with the organic components of the pollen grain chemically attacks the outer layer and breaks down the compounds that cause adhesiveness. After the oxidation reaction the ozone decomposes to oxygen and water without leaving active substances on the surface. More on the machine: ozone water machine.

The two-cloth method for removing pollen

The two-cloth method is the practical working procedure for removing pollen with ozone water. A first cloth lightly moistened with freshly produced ozone water is moved across the pollen-contaminated surface. Contact time of the ozone water with the pollen grains determines the intensity of the oxidation reaction. A second dry cloth removes the loosened pollen residues. That second step is essential: oxidised pollen components must be physically removed from the surface. Full procedure: two-cloth method.

Seasonal pattern: when pollen are most present

Trees such as birch hazel and alder bloom early in spring. Grasses follow in late spring and early summer. Some weeds such as mugwort produce pollen into autumn. During flowering seasons air concentration of pollen is highest and daily presence of pollen on outdoor surfaces and surfaces in ventilated spaces is the norm. In those periods higher cleaning frequency for the most exposed surfaces is practically necessary for people who experience problems with pollen accumulation in their environment.

Which surfaces accumulate the most pollen

Outdoor surfaces are most exposed to pollen accumulation: car paint windows garden furniture and facades collect new pollen layers daily during pollen season. Indoor surfaces in ventilated spaces such as window sills furniture near open windows and floor surfaces collect pollen carried indoors by air circulation. Textiles and clothing are particular surfaces: pollen grains can penetrate deeply into the fibres making removal more challenging than from hard surfaces.

Removing pollen in the home

Furniture floors window sills and other indoor surfaces collect pollen via air circulation from outside. Hard surfaces such as tables cabinets and worktops are well accessible for the two-cloth method with ozone water. Pollen grains adhere to those surfaces at the outer layer without penetrating deeply into the material. More on removing pollen indoors: removing pollen home.

Removing pollen from the car

Car paint windows and the dashboard are particularly susceptible to pollen accumulation. Car paint has an electrostatic charge that attracts pollen grains. In wet conditions pollen grains on the paint surface can dry and leave a yellow or green film that is harder to remove than fresh pollen. Timely removal of fresh pollen with ozone water via the two-cloth method prevents that dried pollen layer from forming. More on removing pollen from the car: removing pollen car.

Removing pollen from windows

Windows collect pollen both on the outside through direct exposure and on the inside via ventilated air. On glass removal of pollen with ozone water via the two-cloth method leaves a streak-free result when the second dry cloth thoroughly dries the surface.

Removing pollen from clothing

Clothing from textiles is a challenging application: pollen grains penetrate into the fibres and are harder to remove than from hard surfaces. For clothing that cannot be washed immediately lightly shaking or tapping outdoors is the first step before ozone water is applied to the affected zones.

Removing pollen from garden furniture and the workplace

Garden furniture stands outdoors throughout pollen season and collects daily new pollen layers on plastic metal and fabric upholstery. Regular treatment with ozone water via the two-cloth method keeps garden furniture free of accumulated pollen layers. At the workplace desk keyboard and other contact surfaces are the primary locations for pollen accumulation via air circulation in office and home working spaces.

Removing pollen without chemicals

Ozone water is a water-based method for removing pollen from solid surfaces. After the oxidation reaction the ozone decomposes to oxygen and water without leaving active chemical substances on the surface. That property connects to the broader approach of cleaning without traditional cleaning agents: cleaning without chemicals. More on what pollen are: what is pollen.

Pollen types and adhesion per type

Not all pollen adhere equally strongly. Birch pollen are relatively small around 20 micrometres and aerodynamically optimised for wind dispersal. They adhere lightly but occur in such large quantities that they form a visible yellow layer on horizontal surfaces. Grass pollen are larger and rougher on their surface causing them to adhere more firmly to textile surfaces. Pollen from pollinating flowers such as roses are much larger and stickier but are less dispersed through the air and occur mainly on plants and in the immediate vicinity of the flowering plant.

Removing pollen: dry or wet

A practical question in removing pollen is whether dry or wet cleaning is more effective. Dry wiping with a dry cloth or brush moves pollen from the surface into the air from where they settle again on the surface or on nearby surfaces. Wet cleaning with ozone water binds the pollen grains and the oxidised fragments in the moist cloth so they are actually removed from the surface rather than just moved. For people experiencing problems with pollen accumulation in their environment wet cleaning with ozone water is therefore the most effective approach.

Indoor air quality and pollen

Pollen entering through open windows and doors settle on all horizontal indoor surfaces: floors window sills furniture and worktops. Regular cleaning of those surfaces with ozone water via the two-cloth method removes the settled pollen from the surface. Additionally air purifiers with HEPA filters help filter pollen from indoor air. The combination of surface cleaning with ozone water and air filtration gives the most complete result for reducing pollen concentration in the indoor environment.

Practical tips for pollen season

Several practical measures reduce the pollen load in and around the home during pollen season. Rinsing outdoor surfaces with water or treating with ozone water early in the morning reduces the pollen layer before the day begins. Keeping windows closed on high pollen count days reduces the influx of pollen indoors. Wiping down clothing on entry prevents pollen from outside being brought inside. More on the background of pollen: what is pollen. Cleaning in relation to pollen allergy: pollen allergy cleaning.

Materials and surfaces requiring extra attention

Some materials require extra attention when removing pollen. Car paint is susceptible to mechanical damage if pollen are removed with a dry cloth; the two-cloth method with ozone water avoids that risk because the ozone water loosens the pollen grains before they are removed. Wooden garden furniture with an open structure can retain pollen grains in cracks and joints; a soft brush soaked in ozone water gives better access to those hard-to-reach spots. Textiles absorb pollen into the fibres making wet cleaning with ozone water only partially effective; washing in the washing machine gives the most complete result for textiles.

Regional and climate-related differences in pollen load

Pollen load varies considerably by region and climate. In the Netherlands and Belgium spring is the period with the highest air concentrations of tree pollen with peaks during the birch flowering season in April and May. In Germany peak periods are similar but shift depending on geographical location. Urban areas sometimes have higher pollen concentrations than rural areas because heat island effects extend the flowering duration. In coastal areas sea wind somewhat reduces pollen concentration. Those regional differences determine the intensity of the cleaning routine needed during pollen season.

Costs and affordability

An ozone water production system structurally deployed for removing pollen from surfaces reduces consumption of conventional cleaning products for those applications. Questions? get in touch. Full overview: knowledge guide.
