Removing pollen from clothing: washing, shaking and wiping
Removing pollen from clothing is more challenging than removing pollen from hard surfaces. Pollen grains penetrate into the fibres of textiles and attach to the individual fibres via the sticky outer layer and electric charge. The deeper the pollen grains are in the fibres the harder they are to remove without washing the clothing. Clothing worn outdoors continuously collects new pollen grains during pollen season that land on the textile via wind and direct contact with flowering plants. Clothing worn indoors or hanging in a closed wardrobe collects pollen via air circulation in the home but to a lesser degree. The most effective method for fully removing pollen from clothing is washing at minimum 40 degrees. At lower wash temperatures pollen grains partially remain in the fibres. For clothing that cannot be washed immediately there are practical intermediate steps: shaking outdoors, lightly tapping and applying ozone water to the exposed zones of the outer layer of the garment. Ozone water is with clothing a supplementary tool not the primary removal method. This article describes the approach per textile type, the role of ozone water with clothing and the most effective combination of steps for removing pollen from different garments including outdoor clothing bedding and accessories.
Removing pollen from clothing: how pollen adhere in textiles, when washing is the most effective method and the role of ozone water as a supplement to shaking.
Removing pollen from clothing: per textile type and situation
Why pollen adhere so strongly to textiles
Pollen grains adhere to textiles via two mechanisms: the sticky outer layer of the pollen grain nesting in the spaces between the textile fibres, and the electric charge of the pollen grain attracting the fibres. The finer the fibre structure of the textile the more contact points there are for the pollen grains to attach to. On smooth densely woven textiles such as polyester or nylon pollen adhere less strongly than on coarsely woven or fluffy textile types such as wool, fleece or velvet. More on the basic mechanism: ozonewater.
Washing: the most effective method
Washing at minimum 40 degrees is the most effective method for removing pollen from clothing. Warm water movement and detergent together release the adhesion of pollen grains to textile fibres and rinse them out of the garment. At 30 degrees or cold washing the releasing action is less powerful and pollen grains partially remain in the fibres. More on the ozone water machine: ozone water machine.
Shaking outdoors as a first step
Shaking outdoors is the first step for clothing that cannot be washed immediately. Vigorously shake the garment or tap it over a rail: loose pollen grains on the outside of the textile are dislodged. Always do this outdoors to prevent dislodged pollen grains from loading indoor air. After shaking the garment contains fewer loose pollen but is not completely pollen-free. The two-cloth procedure: two-cloth method.
Ozone water as supplementary treatment
Ozone water is applicable with clothing as a supplement after shaking for garments that cannot be washed immediately. Apply ozone water lightly to the outer layer of the garment via a lightly moistened cloth. The oxidation reaction reacts with the organic pollen components on the outermost fibre layer. Pollen grains sitting deeper in the fibres are less well reached than on hard surfaces. The effect with clothing is therefore more limited than on hard smooth surfaces.
Delicate textiles: wool, silk and linen
Wool has a scale structure on the fibre that holds pollen grains firmly: shaking removes loose pollen, dry cleaning or washing at wool temperatures is needed for deeper removal. Silk is sensitive to moistening: apply ozone water cautiously and sparingly to silk garments and always consult the care label. Linen has a strong fibre structure that absorbs fewer pollen than wool but more than tightly woven synthetic textiles. For all delicate textile types: the care label determines the maximum treatment intensity. More on pollen indoors: removing pollen home.
Sportswear and outdoor clothing
Sportswear such as running jackets, cycling jerseys and hiking trousers collect large amounts of pollen during outdoor activities in pollen season. Those garments are typically washable at higher temperatures. Washing after each outdoor activity during pollen season is the most effective approach. Before bringing sportswear indoors shaking outdoors is worthwhile to limit direct transfer of pollen grains to indoor air. More on the general pollen removal approach: removing pollen overview.
Bedding and nightwear
Bedding and nightwear are categories where pollen load deserves particular attention. An open bedroom window lets pollen in that settle on bedding. Washing bedding at minimum 60 degrees during pollen season more frequently than outside pollen season reduces pollen load in the sleeping environment. Pillowcases are particularly relevant: the face and eyes lie directly on the pillowcase during sleep with pollen grains on that pillowcase able to make direct contact with mucous membranes. Weekly washing of pillowcases at 60 degrees during pollen season is an effective measure.
Clothing on the coat rack: a route for pollen entry
Clothing hung directly on the coat rack indoors after outdoor use brings pollen grains into the indoor environment. The pollen grains on the clothing settle on the floor and furniture below and are further spread through the room via air circulation. Shaking outdoor clothing before going inside and placing a special outdoor zone in the hall for outdoor clothing are practical measures that reduce pollen entry via clothing into the indoor environment.

Accessories and small garments
Scarves hats gloves and caps are small garments that quickly collect pollen during pollen season and also load the inside of the car the bag and the jacket pocket with pollen grains. Weekly washing of used accessories during pollen season keeps the pollen load low. Caps with a stiff brim are less easily washable than soft hats; a hand wash with water typically suffices for removing the surface pollen layer from a cap. More on the general approach: removing pollen.
Tumble drying versus outdoor drying during pollen season
Drying clothing after washing is a moment when pollen can be re-applied to the washed clothing. Clothing dried outdoors collects new pollen grains during drying that settle from outdoor air on the moist textile. The moist surface of the clothing increases adhesion of pollen grains to the textile. Drying indoors or in a tumble dryer prevents that re-pollination. Those who dry outdoors during pollen season should preferably hang washing after the morning dew has dried and bring clothing in before late afternoon when pollen concentration in outdoor air is typically at its highest.
Clothes hanger and wardrobe: pollen in the wardrobe
Clothing stored indoors in an open wardrobe or on an open clothes rail is exposed to pollen grains settling via air circulation in the room. During pollen season clothing not frequently washed such as blazers, jackets and evening wear can accumulate pollen grains during the storage period. Storing clothing in closed wardrobes or covering less frequently worn garments with a garment bag reduces that pollen accumulation in the wardrobe. A periodic check of stored clothing with a dry soft brush and shaking outdoors is a supplementary measure for clothing not worn for a long time during pollen season.
Children's clothing and school clothes
Children are often more active outdoors than adults and come into direct contact with grass and flowering plants through play and sport. School clothing and outdoor play clothes therefore collect more pollen than office clothing or clothing worn for quiet outdoor activities. Daily washing of school clothing during pollen season is for children with increased sensitivity to pollen an effective measure that reduces daily pollen exposure via clothing. Children's sportswear should always be washed after use before use the next day.
Pollen and dark versus light textile colours
Yellow and green pollen grains are most visible on dark coloured clothing. On black, dark blue or dark green clothing the yellow pollen layer after outdoor use is immediately visible. On light or white clothing pollen grains are less immediately visible but that does not mean they are less present. For people sensitive to pollen the colour of the clothing is not determining for the degree of pollen contact: dark clothing that makes pollen visible actually provides a useful indication of the pollen load on the garment.

Pollen on head coverings and hats
Hats caps and head coverings are clothing accessories worn directly above the face forming a route for pollen grains that fall from the head covering onto the face and eyes. Cleaning hats and caps with a lightly moistened cloth with ozone water on the outside removes loose pollen grains from the surface. Fabric or felt hats are less suited for wet cleaning; brushing outdoors followed by storing in a sealed box is the most cautious approach for those materials.

Washing clothing as a routine during pollen season
A deliberate washing pattern during pollen season differs from the washing pattern outside pollen season. Garments that after outdoor use would normally be worn several times before washing are during pollen season washed after each outdoor use. That increased washing frequency is for the duration of pollen season an effective measure. After pollen season the normal washing pattern returns. It is useful to track the start and end of pollen season for the most relevant pollen species in your own region to limit the increased washing frequency to the truly necessary period.
Smell and pollen: air freshener versus ozone water
Clothing that has hung outdoors for a long time or that has collected a lot of pollen can leave a scent trail containing pollen components. Conventional air fresheners or textile sprays mask that scent but do not remove pollen grains from the fibres. Ozone water applied to the outer layer of the garment reacts with the organic pollen components and chemically breaks them down which also reduces the smell those components cause. Washing at 40 degrees is also in this context the most effective method for fully removing pollen residues and the associated smell. More on removing pollen indoors: removing pollen home.
