"Using a handheld pressurized steam cleaner at 212°F melts greasy kitchen grout, blasts grime out of shower door tracks, and sanitizes mattress ticking without harsh chemicals or soaking."

The science

  1. Heat loosens grime

    Steam can soften and dislodge soil on suitable hard surfaces, especially in tracks and grout joints.

  2. Sanitizing is conditional

    A steam tool's outlet temperature does not establish the temperature or dwell reached throughout mattress ticking. Avoid a broad sanitization claim without a validated process.

  3. Moisture must leave

    Steam can deposit water in textiles. Dry mattresses fully with airflow and follow both the mattress and steam-tool care instructions.

Do this instead

Follow product and surface manufacturer instructions. Never mix cleaners.
