Q. What are health and safety considerations when selecting and using a medical device cleaning agent?
A. Human health and safety considerations include detergent toxicity, corrosivity, reactivity, and flammability. These considerations can be evaluated by reviewing a Safety Data Sheet for the solvent, chemical, or detergent with which you intend to clean. Learn More.

Q. I just received your chapter on cleaning SOPs and I look forward to reading it. In parallel, I was hoping to get your thoughts or a bit of advice on how to create and implement cleanliness specifications/processes for machined (PTFE) plastic parts. Cutting fluid for the machining center is basically a water soluble vegetable oil-based fluid. The use of this plastic manifold and cover is within an electro-mechanical-fluidic subsystem (“Delivery Module”). This delivery module accumulates a quantity of 59wt% Hydrogen Peroxide that has been … Click to Read The Full Question and Answer.

Q. How do you clean wax marks on optical lenses which are difficult to remove?
A. Use either 1% Alconox or Liquinox in a heated 160 deg F ultrasonic bath followed by a deionized water rinse to clean optical lenses during manufacturing.

Q. We need to find an alternative cleaning solution we can use to sonicate metal (hardened steel) tools with that won’t rust them.

A. Hardened tool steel is prone to flash rusting on exposure to water and humidity with dissolved oxygen if there are no corrosion inhibitors present. You can clean tool steel in a warm Alconox solution (less than 120 deg F or less than 45 deg C) followed by an ambient temperature rinse (circa 70 deg C or 20 deg F) and a rapid …
