The Remnant Difference
Steri-clean Company
Superficial Sanitization
Standard cleaning only treats visible surfaces, leaving hidden pathogens and odors trapped deep within.
Remnant
Deep-Level Decontamination
We eliminate biohazards at the molecular level, using advanced ATP testing to guarantee 100% decontamination.
Whether the call comes from Spokane, Spokane Valley, Liberty Lake, Cheney, Airway Heights, or Mead, a technician is close by.
Why Drug Cleanup in Spokane Has to Be Done Right
Spokane County recorded 346 confirmed overdose deaths in 2024, with fentanyl involved in roughly 80% of them, and most of those happened in homes occupied by working adults. That's a meaningful detail for anyone who owns property here, because contamination after an overdose, an arrest, or long-term use doesn't always look obvious. Trace residues settle into carpet, drywall, and HVAC systems, and they stay there until the right cleanup is done.
If law enforcement has identified a property as a former meth lab, the situation is more serious. State law requires the property to be decontaminated by a certified contractor and cleared by testing before anyone can move back in. Renting it out, selling it, or returning to it without that step creates real legal exposure for the owner and a real health risk for the next person who walks through the door.
Our Step-by-Step Drug Cleanup Process
Site Assessment
A technician evaluates the property, reviews any law enforcement documentation, and identifies the type and scope of contamination.
Containment Setup
Sheeting and air filtration close off the affected space so airborne particles and residues stay contained during the work.
Soft Good Removal
Mattresses, upholstery, carpet, padding, and porous items that have absorbed residue are extracted and bagged for disposal.
Surface Decontamination
Walls, ceilings, hard flooring, and fixtures are washed with chemistry suited to the specific drug residue present.
HVAC and Air Treatment
Ductwork is cleaned or replaced where needed, and HEPA scrubbers run until airborne contamination is cleared.
Clearance Testing
Surface samples are pulled and analyzed to confirm levels meet Washington decontamination standards.
The Equipment and Products We Use
Drug residue work needs gear most cleaning crews don't carry. Our technicians wear Tyvek suits, full-face respirators, double-layered nitrile gloves, and sealed boot covers, because fentanyl and methamphetamine residues can be absorbed through skin or inhaled in trace amounts. Negative-air HEPA scrubbers run the whole time to keep particles from drifting into the rest of the home.
Cleaning chemistry is matched to the drug involved. Methamphetamine and fentanyl don't break down the same way, so we don't use the same product for both. Surfaces are sampled before and after to confirm levels are safe, and the results are documented for the property owner. If meth lab clearance is required, the work is done to the standards Washington uses for reoccupancy.

Still Have Questions?
What is crime scene cleanup?
Crime scene cleanup is a specialized service for restoring properties after traumatic events. Once law enforcement releases the scene, hazardous materials like blood and bodily fluids remain. Biohazard cleanup companies handle these risks, ensuring safe disposal and decontamination of hazardous materials.
What is biohazard cleanup?
Biohazard cleanup includes crime scene and trauma events, medical and accidental incidents, drug-related hazards, animal-related biohazards, and hoarding. Our expertly-trained cleanup technicians are stationed across the Pacific Northwest to rapidly remediate properties and vehicles impacted by biohazards.
What is unattended death and suicide cleanup?
Unattended death and suicide cleanup involves the professional removal of biohazards such as blood, bodily fluids, and other contaminants left behind after a traumatic event. These situations often carry serious health risks due to decomposition or exposure to pathogens, and require specialized cleaning, disinfection, and odor removal. Remnant handles these scenes with discretion, compassion, and care—restoring the space safely and thoroughly. Our team ensures the affected area is properly cleaned, sanitized, and ready for safe reentry.
What is blood cleanup?
Blood cleanup is the professional removal, disinfection, and proper disposal of blood and any materials it has contaminated. Because blood can carry harmful pathogens like HIV, Hepatitis B, and Hepatitis C, it’s classified as a biohazard and requires specialized training, protective equipment, and proper handling protocols.
