Spring Cleaning Series: Part 3 of 3

Many of us see spring as the time to refresh our homes after the winter weather wanes. If your to-do list only contains indoor chores, add your outdoor spaces to the mix, so your entire home is ready for the season.

Not sure where to start? We’ve created an outdoor deep spring cleaning checklist you can follow. We’ve broken it down into sections to streamline and de-stress the cleaning process.

Before you start cleaning, we recommend completing the following tasks:

  • Check the warranty and care instructions for any items you own, and follow the suggested cleaning methods.
  • When working with harsh chemicals and pressure washers, always wear goggles, gloves, a facemask, boots, and ear protection.*
  • Block off your work area so curious kids and pets can't wander in by mistake.

*NOTE: Some of the cleaning methods below include bleach. If you prefer a natural alternative, we recommend undistilled white vinegar.

Siding

IMPORTANT: This method works on many types of siding, including wood, vinyl, and others. However, pressure washer psi levels will differ depending on the material. Check manufacturer recommendations before cleaning.

Supplies Needed


  • Garden hose with spray nozzle

  • Mildewcide

  • Garden sprayer

  • Soft-bristle siding brush

  • Pressure washer (use the appropriate psi level for your siding type) equipped with a 25- or 40-degree fan tip

Instructions


  1. Spray siding with the hose to remove loose dirt and debris. 
  2. Mix the mildewcide according to the product instructions in the garden sprayer. 
  3. Test the cleaner in an inconspicuous area first to ensure it won’t harm the siding. 
  4. Spray your siding with the mildew solution straight on (not at an upward angle), starting from the bottom and working up. 
  5. Scrub the siding with the soft-bristle brush. 
  6. Rinse from the top down with the pressure washer. To prevent damage, select the appropriate psi level and fan tip, keep the wand at least three feet away, and move in smooth, even strokes. 
  7. Allow the siding to air-dry completely before replacing decor and fixtures.*

*NOTES: 

  • Avoid cleaning siding in direct sunlight to prevent rapid drying or streaking. 
  • If you have nearby plants or landscaping, move or cover them with a breathable fabric drop cloth beforehand. 
  • Prolonged moisture exposure on wood siding can lead to mold growth.

Pressure Washer Tips

Pressure washers are used in many deep spring cleaning checklists in this guide, so we dedicated a section to safely using these powerful tools.

Which Materials Can Be Pressure Washed?

Browse the chart below to see which materials are safe to pressure wash and which are not.

A chart displays information about which materials are safe to pressure wash and which are not.

Know Your Pressure Washer Nozzle

Pressure washers typically come with multiple color-coded nozzle heads you can attach to the spray wands. The different colors indicate the nozzles’ spray pattern degrees, so you can quickly pick the correct one for your outdoor project. Use the handy chart below for easy nozzle navigation.

A graphic displays information about different pressure washer nozzle colors, spray patterns, and correct uses.

Safety Tips

  • Do not use a ladder when pressure washing siding, as the recoil can cause you to lose balance. Instead, use scaffolding for a safer way to reach high spots.
  • Always spot-test and check the results before cleaning the entire surface to ensure you're using the proper setting on your pressure washer.
  • Use the correct psi when cleaning with your pressure washer.
  • Do not spray surfaces at an angle.
  • Always wear gloves, goggles, boots, a face mask, and ear protection when using a pressure washer.

FAQs

What’s the difference between a deep clean and a spring clean?

A deep clean is a thorough scrub session you can perform when you have an item or space in dire need of tidying up. It takes more time, extra steps, and additional equipment to deep clean something since you're addressing all of it—including the nooks and crannies often skipped during routine cleanings. A spring clean is performed after the winter season ends to refresh spaces. Both are more involved than a standard cleanup. 

What do you throw away during spring cleaning?

When spring cleaning, throw away expired or damaged items. This includes treated or rotted wood, old lightbulbs, and broken glass. If you have things you no longer use that are still in good shape, like gardening tools or plastic planters, donate or recycle them.

What month should you start spring cleaning?

March is typically the month when homeowners start spring cleaning outside. However, if you live in a colder climate and see disagreeable weather during that time, there's no problem with waiting a little longer. On the other hand, if you live in an area with pleasant weather before March, you can start spring cleaning early.
