Hey Robin. For disinfecting non-food contact areas such as the office equipment you mention above you aren't required to wipe it off after the 10 minute contact time. However, after that time you can wipe if necessary. The product won't leave a residue when used at the correct dilution rate provided on the label. Thank you for your question. We appreciate you considering our product.

Hi Elisa. Our registered kill claims are only valid on hard, nonporous surfaces and we don't recommend spraying directly on to food. Elisa, give us a call at 1 (866) 999-7484 between 8-5 CST Monday through Friday, and provide Code MMC48 to the representative. We can have a Member of our product team give you a shout to discuss in more detail if you'd like. Thanks!

Hey Herb. Yes it is safe for those applications. It won't harm wood or aluminum. Thank you!
