Do keep some towels around just in case your bucket suffers a major spill. Play it extra safe and lay one out to set your bucket on while you work.
Photos, posters, or other artwork. Shelves, coat hooks, or other functional items. Electronics, like wall-mounted TVs or speakers.
Keep in mind that you’ll be carrying that bucket around the room with you. Depending on the size of your bucket, adjust the amounts as needed to keep it only halfway filled to avoid spills.
Use soft sponges (as opposed to a more abrasive kind meant for scrubbing burnt food), especially if your walls are painted. Using tougher sponges could ruin your paint’s surface. Sponges in bolder colors may leave their color on the wall.
Extremely dirty walls may require a ratio of 2 parts vinegar to 3 parts water.
If your walls are painted, abrasive agents like baking soda may damage the paint, especially if it’s latex-based. If your solution starts ruining your paint job, you may need to apply a fresh coat rather than clean.
Additionally, you should use a second sponge for rinsing. As with the rinsing water, replace as needed if it becomes too foul as you move along.
If you’re working on a ladder, you may want to work on even smaller sections since you may be going up and down in between the washing, rinsing, and drying.
