The food safety experts at FoodSafety.Gov confirm this is indeed true. "Shelf-stable commercial mayonnaise is safe when stored at room temperature after opening." Its important to note that this all becomes null and void if the mayo gets contaminated by dirty utensils or fingers.
Commercially produced mayonnaise does not require refrigeration because it is highly acidic, contains pasteurized eggs, and is made with high-quality oils, creating a hostile environment where bacteria cannot thrive.
Condiments rich in natural preservatives (salt, sugar, or vinegar) or fermented ingredients don't require refrigeration for food safety. The pantry is ideal for Honey, Soy sauce, vinegar-based hot sauces, fish sauce, and nut butters, as the environment deters bacteria and mold.
Longer than four months is when mayonnaise can go bad and become unsafe to eat. Generally, it's safest to throw mayonnaise away if the best-by date has passed. If it has an expiration instead of a best-by date, you must throw it away once the date has passed to avoid illness.
Cans: up to 100 years
Soft drink cans and canned food tins are made from aluminum, a material that can take between 10 and 100 years to decay, depending on the thickness, and which generates iron oxide. For this reason, it is important the waste recycling.

A small amount of mayo on a soft cloth is surprisingly effective for cleaning houseplant leaves, and yes, they'll smell absolutely fine afterwards.

According to some researchers, plastic water bottles could take upwards of 450 years to decompose. That's equivalent to 5,400 months, or 21,600 weeks, or 1,971,000 days just for one single plastic bottle to decompose.
The United States produces the highest total volume of plastic waste globally, generating roughly 34 million metric tons annually. However, when measuring ocean pollution and mismanaged waste, the Philippines and India are the leading contributors due to limited local recycling infrastructure.
The hardest things to decompose are inorganic, human-made materials. Glass bottles and Styrofoam are generally considered the hardest to break down.
