What helps us review a message

Include the full Clean Home Lab page URL.

For a correction, link to a current manufacturer, public authority, or standards source where possible.
Describe the issue without sending passwords, financial data, government identifiers, medical records, or unrelated personal details.

Email provider

All three @czhhsh.com mailboxes use Tencent's domain email service. Message content and delivery metadata may therefore be handled through Tencent's email infrastructure under its own terms and privacy practices.

Clean Home Lab does not claim a Tencent delivery or availability SLA, and it does not promise a fixed reply time. A message may be delayed, filtered, or fail in transit. Keep a separate copy of anything important.

Safety boundary

Email cannot inspect a home, diagnose a product, direct an active emergency, or replace a qualified local professional. For smoke, fire, suspected gas, electric shock, poisoning, serious symptoms, or another immediate danger, contact the appropriate local emergency service, utility, poison-control service, or medical provider.

Privacy requests

Provide enough context to locate the relevant interaction, usually the sending email address and approximate date. Do not attach identity documents unless we first explain why limited verification is reasonably necessary. Anonymous technical or aggregate records may not be linkable to a named person.
