Allergy Season Cleaning Tips for Willamette Valley Homes

The most useful allergy season cleaning tips all do one of two things: keep pollen from getting inside, or remove it from the places it settles before it gets stirred back up. In the Willamette Valley that means entryways, bedding, floors and air filters, cleaned more often from late spring into early summer when grass pollen runs high.

Why the Willamette Valley is tough on allergies

The valley grows a lot of grass. Oregon State University's field crops program describes the Willamette Valley as the grass seed capital of the world, and notes that it produces almost two-thirds of the total cool-season grass seed grown in the United States. You can read more on OSU's Willamette Valley grass seed page.

Add lawns, pastures and roadsides, and grass pollen season is a big deal here. A local allergist told OPB that grass pollen season in the valley typically runs from late May to July. Read the OPB report on the Willamette Valley allergy season for more on how weather affects it year to year.

Tree pollen comes earlier in spring, so for many people in Salem, Albany, Corvallis and Eugene the sneezing starts well before grass season and carries through it. Cleaning will not replace medical care. If your symptoms are severe, talk to your doctor or an allergist. What cleaning can do is make your home a place where you get a break from pollen.

How pollen gets into your home

Pollen does not need an open window to get inside, although that helps it. It comes in on:

• Clothes, hair and shoes after time outdoors
• Pets, especially dogs who roll in the grass
• Open windows and doors on warm, breezy days
• Air leaks around doors, windows and vents
• Grocery bags, backpacks and outdoor gear set down on furniture

Once inside, it settles on floors, beds, upholstery, curtains and every flat surface, and it goes airborne again every time someone walks across the rug or flops onto the couch.

Allergy season cleaning tips for every room

Entryways

1. Put a mat outside and inside every door you use.
2. Take shoes off at the door and keep them there.
3. Have a spot near the entry for jackets and bags that have been outside.
4. Wipe dogs down with a damp towel when they come in.
5. Vacuum or shake out entry mats often. They fill up fast in spring.

Bedrooms

• Wash bedding weekly in the hottest water the fabric care label allows. Pillowcases matter most, since your face is on them all night.
• Shower and change before bed on high-pollen days, so you are not carrying pollen into the sheets.
• Keep pets off the bed during peak season if you can manage it.
• Keep bedroom windows closed during the day when pollen counts are high.
• Cut the clutter. Stacks of clothes, piles of pillows and open shelving all hold dust and pollen.

Floors and furniture

• Vacuum with a HEPA-filter vacuum at least weekly, and more often on rugs and carpet near entries. A weak filter blows fine particles back into the room.
• Mop hard floors after vacuuming to pick up what is left.
• Vacuum upholstered furniture and the underside of cushions.
• Damp-dust surfaces with microfiber instead of a dry duster, which just moves pollen around.
• Wash throw blankets and decorative pillow covers along with the bedding.

Air and windows

• Replace your HVAC filter at the start of the season and check it monthly. Use the highest-rated filter your system is designed for.
• Run a portable HEPA air cleaner in the bedroom.
• Wipe window sills and tracks. Pollen collects there, especially on windows that were open.
• Wash or vacuum curtains a couple of times through the season.

A spring cleaning checklist built for allergy season

The best time for a big reset is right before grass season, so your home starts clean. A deep spring clean should cover:

1. Ceiling fan blades, light fixtures and the tops of door frames
2. Blinds, curtains and window tracks
3. Baseboards, vents and return grilles
4. Behind and under furniture, including beds and couches
5. Mattress and upholstery vacuuming
6. Closet floors and shelves
7. Entry mats replaced or deep cleaned
8. A fresh HVAC filter
9. Pet beds washed
10. Bathroom and kitchen surfaces, including exhaust fan covers

After that, a regular weekly or bi-weekly clean keeps pollen from building back up through the season. Our guide on how often you should get your house cleaned can help you pick a rhythm.

Where professional cleaning helps

The last of these allergy season cleaning tips is the simplest: allergy season is when a lot of people are least able to do the cleaning themselves. Vacuuming and dusting stir pollen up, and the person with allergies is usually the one who feels it. That is a good reason to hand off the work.

Our residential cleaning service covers regular weekly, bi-weekly or monthly cleans, deep and spring cleaning, and window and baseboard detailing. We bring our own supplies and equipment and use eco-friendly products as standard. If anyone in the home is sensitive to particular products or scents, tell us at the walkthrough and we will work around it. Our post on green cleaning products that are safe for kids and pets goes into product choices.

Offices feel allergy season too. Shared spaces with carpet, fabric chairs and doors opening all day collect pollen fast. Our office cleaning programs include carpet vacuuming and floor care, run after hours, and use lower-irritant eco-friendly products in spaces where people spend forty hours a week. For larger facilities, our janitorial services put a dedicated crew on a fixed schedule. We serve homes and businesses in Salem, Albany, Corvallis and Eugene.
