Things You'll Need:
- Trisodium phosphate (TSP-available at home-centers).
- Telescoping scrub-brush (also available at home-centers).
- Bucket (large enough for brush head)
- Hose(s), spray nozzles
- Work gloves and/or rubber gloves
- Ladder (possibly)
- Drinking water, other comfort items.
-
Step 1
Mix the cleaning solution:
Read and follow manufacturer's label instructions for working with and mixing the TSP powder with water (for cleaning), in a bucket large enough to accept your brush-head. -
Step 2
Preparation:
If your house is a ranch style, you might not need a ladder, depending on the lay of the land around the building.
If it is not a ranch, you most likely will need a ladder.
Be sure to practice safe ladder use. -
Step 3
From the ground and/or ladder, hose a section of the house down to rinse off surface dust, pollen, etc.
-
Step 4
Once an area is wet, dip your brush head in the TSP/water solution and brush the siding, starting as high as you can reach with the telescoping brush.
Start by working an area about 20 feet wide and work the entire height of the siding for that width if you can.
As you learn the process, you may choose to increase your working area, but try to avoid too large an area, as the cleaning solution may dry before rinsing, which can create streaks or may require repeat brushing. -
Step 5
Working from top to bottom, thoroughly brush the area you are working on.
Use both horizontal (side-to-side) and vertical (up-and-down) motions, to ensure thoroughness. -
Step 6
Once you've brushed thoroughly, rinse with clean water.
Repeat this process for the entire house.
