The short answer
Initial Skimming
When ash falls into your pool, the first step is to remove as much as possible from the surface. Use a leaf net or skimmer basket to scoop out large clumps. Work slowly to avoid breaking them into finer particles that sink.
Ash can be alkaline, so wearing gloves and a dust mask while handling it is wise. If you see a thick layer, consider draining some water to reduce the load. This step is straightforward and can be done without special tools.
Vacuuming Techniques
After skimming, vacuum the pool floor. Set your vacuum to the waste or backwash setting so the ash goes out of the system rather than clogging the filter. Move the vacuum slowly to avoid stirring up settled ash.
If you have a robotic cleaner, check if it has a fine filter for small particles. Otherwise, manual vacuuming gives you more control. For very fine ash, you may need to repeat the process a couple of times.
- Use a leaf net first for large debris
- Vacuum on waste setting to bypass filter
- Brush walls and floor to loosen stuck ash
- Check and clean the skimmer basket frequently
- Consider a pool clarifier to help settle fine particles
Brushing and Filter Care
Ash can cling to pool walls and the floor. Use a pool brush to scrub these surfaces, focusing on corners and steps. After brushing, give the water time to settle so the ash drops to the bottom for vacuuming.
Your filter will likely need attention after this cleanup. Backwash a sand or DE filter, or rinse a cartridge filter thoroughly. A clogged filter reduces water flow and circulation, making the pool harder to clean.
Water Chemistry Balance
Ash can affect your pool's pH and alkalinity. After cleaning, test the water and adjust as needed. The goal is to keep pH between 7.4 and 7.6 and alkalinity in the 80 to 120 ppm range. This helps prevent corrosion or scaling.
If the ash came from a wildfire, it may contain more than just wood residue. In that case, a more thorough water test for metals or other contaminants is a good idea. Your local pool supply store can help with testing.
When to Call the Pros
If the ash layer is deep, or if the pool has been sitting with ash for days, the job may be too much for a typical homeowner. Heavy ash can clog filters and require repeated draining and refilling.
Local water damage pros have industrial vacuums and filtration systems designed for fine particles. They can also assess whether the ash has affected your pool equipment. If you're in Redmond, a professional cleanup might save you time and prevent long-term damage.
- Deep ash layers that are hard to remove
- Filter clogging repeatedly despite cleaning
- Ash mixed with other debris like leaves or dirt
- Concern about water contamination from wildfire ash

Can I use a regular pool vacuum to remove ash?
Yes, a regular pool vacuum can work, but you must set it to the waste or backwash setting. This sends the ash out of the system instead of through the filter. For very fine ash, a vacuum with a fine filter bag may be more effective.
Will ash damage my pool filter?
Ash can clog a filter quickly if it goes through the normal cycle. Using the waste setting helps avoid that. If ash does get into the filter, backwash or rinse it thoroughly. Repeated clogging may indicate you need professional cleaning.
Is it safe to swim after cleaning ash from the pool?
After you remove the ash and balance the water chemistry, it is generally safe to swim. However, if the ash came from a wildfire, test the water for metals or other contaminants. When in doubt, wait or consult a pool professional.
