The short answer
Start with Dry Soot Removal
Before any wet cleaning, tackle the loose soot. Use a dry chemical sponge, sometimes called a soot sponge, and wipe the shiplap surface gently with long strokes. Pressing too hard can grind the soot into the wood grain. Work from the top down to avoid streaking cleaner soot over dirty areas below.
Change the sponge surface frequently as it blackens. This dry method prevents the soot from turning into a greasy, hard-to-remove paste when it gets wet. For textured shiplap, pay close attention to the grooves and crevices where soot accumulates. Proper dry removal makes the subsequent wet cleaning much more effective.
Wash with a Gentle Cleaning Solution
After dry cleaning, prepare a mild washing solution. Mix a few drops of a pH-neutral dish soap into a bucket of warm water. Avoid harsh chemicals, ammonia, or vinegar initially, as they can set some smoke odors or damage the wood finish. Test your solution on a small, inconspicuous area first to check for discoloration.
Use a soft cloth or sponge, wring it out well, and wash a small section of the shiplap. Rinse your cloth often in a separate bucket of clean water to avoid reapplying dirt. Work in manageable areas to prevent the cleaning solution from drying on the wood, which could leave streaks or residue.
Rinse and Dry the Wood Thoroughly
Rinsing is a critical step to remove any soap residue and loosened soot. Dampen a clean cloth with plain water and wipe over the washed areas. You may need to change your rinse water several times as it becomes cloudy. For shiplap walls, take care not to let excess water run down and pool.
Allow the shiplap to air dry completely. Open windows and use fans to increase air circulation, which helps prevent moisture from being trapped behind the boards. Proper drying conditions depend on your local climate and indoor humidity. Ensure the wood is fully dry before assessing if odor or staining remains.
Address Persistent Odors and Stains
If a smoke odor lingers after cleaning, the soot may have penetrated deep into the wood or its backing. Surface cleaning alone may not be sufficient. In such cases, specialized odor-neutralizing treatments applied by professionals are often needed to tackle absorbed smoke particles effectively.
Stubborn yellowing or dark stains might indicate that the smoke residue has adhered to the wood finish or varnish. These stains may require targeted chemical treatments or light sanding and refinishing. Attempting aggressive DIY methods could damage the shiplap, so evaluating the extent of the staining is key.
- Test any new cleaner on a hidden spot first.
- Never mix cleaning chemicals like bleach and ammonia.
- Wear gloves, a mask, and eye protection for safety.
- Ensure the room is well-ventilated during the entire process.
- Place drop cloths on floors to protect them from drips.
- Have separate buckets for washing and rinsing solutions.
When to Call for Professional Help
Extensive smoke damage from a large fire often requires professional equipment and expertise. If the shiplap is in a high-ceilinged room, covers a large area, or if the soot is oily and thick, a DIY approach may be inadequate. Professionals have access to industrial-grade cleaning agents and tools designed for porous materials like wood.
Professionals can also assess if the smoke has affected the wall cavities or structure behind the shiplap, which is not visible. They follow a systematic process to clean, deodorize, and verify that the environment is safe. If you live in Meridian, dealing with smoke quickly can help prevent secondary issues in your home's air quality.

Can I use a pressure washer on outdoor shiplap?
Using a pressure washer is generally not recommended. The high pressure can force water behind the boards, leading to wood rot or mold growth inside the wall. It can also splinter or gouge the wood. A garden hose with a gentle spray attachment and soft brush is a safer choice for exterior cleaning.
Will cleaning remove the smoke smell completely?
Surface cleaning might not eliminate deep-set odors. Smoke particles can penetrate wood pores and linger in wall cavities. If a smell persists after thorough cleaning, the issue may be systemic. Professional deodorization techniques, such as thermal fogging or ozone treatment, are often necessary to neutralize embedded odors effectively.
What if the shiplap is painted or sealed?
Cleaning painted shiplap follows a similar process, but be gentler to avoid stripping the paint. Use a mild detergent and soft cloth, testing first. Sealed wood is easier to clean than raw wood, as the finish provides a barrier. However, heavy smoke can still stain or degrade certain finishes over time.
