What materials are the products made from? Are they safe to use with white vinegar or hot soap?

Everything we produce here at Ankomn is made from special Polycarbonate, which is incredibly stable and has a high resistance to corrosion and contamination. It can withstand temperatures of -20 to 85° Celsius or -4 to 185° Fahrenheit, so they can be used safely with most substances including white vinegar, and safely cleaned in hot water.
