The evidence does not specifically name stainless steel or establish the product’s chemistry, so compatibility with specialty finishes is not confirmed.
Why
Windex Original is identified by the manufacturer as a hard-surface cleaner, and no stainless-steel prohibition is provided. Normal use on ordinary stainless steel is reasonably expected to be compatible.
What to do
Use only as directed on the label; apply to a cloth or surface, avoid prolonged dwell, and wipe dry. Spot-test first on coated, brushed, or specialty finishes.
pH
Not stated in the provided evidence.
Relevant chemistry
The provided evidence identifies it as a hard-surface cleaner but does not establish pH or specific chemistry classes.
