Decontamination, done so it actually closes out.

Utah regulates this work specifically

Under the Illegal Drug Operations Site Reporting and Decontamination Act — Utah Code Title 19, Chapter 6, Part 9 — methamphetamine decontamination must be performed by a decontamination specialist certified through the Utah Department of Environmental Quality. This is not a general restoration licence and not a cleaning certification. Ask anyone bidding your job for their DEQ certification before you ask them for a price.

Cleaning is not clearing

The distinction that costs people the most money: scrubbing a property does not change its status. What changes its status is a documented decontamination performed to the state standard, followed by post-decontamination sampling that comes back below the action level, resulting in a certificate of decontamination. Without that paperwork the property stays on the local health department record regardless of how clean it now is.

What the work involves

Scope follows the sampling. Typically: removal of porous materials that hold residue, HVAC system cleaning or component replacement, repeated detergent washing of hard surfaces, encapsulation where removal is impractical, and disposal handled to requirement. Contents are addressed separately — some can be cleaned, some cannot, and pretending otherwise is how a job gets re-opened after clearance sampling fails.

Then it gets verified

Post-decontamination sampling closes the job. When results come back below the threshold, the documentation package goes to the local health department so the property can be released. That package — not our invoice — is the deliverable that matters to a lender, a buyer or a title company.
