Stainless steel is a hard, nonporous surface and generally fits the product’s intended use, but the evidence does not explicitly name stainless steel or establish the chemistry.
Why
Normal use on stainless steel is reasonably compatible based on the manufacturer’s broad hard, nonporous surface claim. The product is a cleanser and polish, so improper or prolonged use could potentially affect finishes.
What to do
Use only where thorough rinsing is possible; follow the product label, rinse thoroughly, and test an inconspicuous area first, especially on coated or specialty finishes.
pH
Not stated in provided evidence.
Relevant chemistry
Chemistry is not established by the provided evidence. Intended to clean and polish most hard, nonporous surfaces.
