01 The verdict
Better not. WD-40 on a microfiber couch risks damage, and there is a safer option for almost every stain.
- Avoid It leaves an oil stain that needs solvent cleaning.
02 Why: the two sides
Microfiber couch
Upholstery carries a cleaning code (W, S, W/S or X) on its tag, and that code decides which liquids are safe.
A microfiber couch cannot be rinsed through, so whatever you put on it partly stays in it.
The fibre in a microfiber couch is synthetic (polyester, nylon or similar): tough against most chemicals, but sensitive to heat and solvents, and it holds oily stains tightly.
WD-40
A petroleum-based lubricant and water-displacing spray. pH n/a.
It is an oil: it leaves an oily stain of its own on fabric and porous surfaces.
03 Use instead
Follow the stain file for the specific stain on microfiber couch; each one picks the safe product for that combination.

08 Questions
Is diluted WD-40 safe on a microfiber couch?

None of the 40 files for microfiber couch uses it. Absence from the model does not establish either effectiveness or safety.
How long can WD-40 stay on a microfiber couch?
