Oxo, a well-known brand of kitchen products and accessories, makes a useful mini-sized silicone measuring cup.
The mini measuring cup holds up to 4oz of liquid, plus some overflow.
It’s easy to hold and pour, and relatively easy to clean.
I bought one for use in the kitchen, as I couldn’t find a replacement for my 4oz glass measuring cup with worn-out markings, and another mini measuring cup for use in the garden.
Does it work well in the kitchen? Yes, although I tend to prefer glass measuring cups. For kitchen tasks, the Oxo silicone measuring cup is less susceptible to temperature swings.
I use my garden-dedicated mini measuring cup for measuring out liquid fertilizer, and other such things.
It won’t break, and it cleans easily.
There are less expensive silicone measuring cups out there. I bought this one because I trust the Oxo brand, and because the markings are very high contrast compared to what I’ve seen from other brands.
I’ve used mine to hold water, oil, vinegar, concentrated liquid-based fertilizer, and dry fertilizers, and can’t speak much about its resistance to other types of liquids or materials.
Surprisingly, it doesn’t seem to hold odors, but I cannot guarantee you’ll have the same experience.
I’m mentioning this measuring cup because I have a very large bottle of way oil, and my machine has a small reservoir, making it too easy to overflow smaller funnels. I’m also prepping to change the oil in my vacuum pump. This seems like a convenient way to measure oil out.
I’ve had great experiences with the measuring cup in other uses, and it seemed like a good idea to bring it up for discussion.
I should add that, once I use a measuring cup (or other container) for non-food-safe liquids, it will never again be used in the kitchen, for food, or similar. Don’t mix up containers used for food and containers used for other purposes.
Pro Tip: If you’re going to put non-food-safe liquids in a container typically used for food-safe products, be sure to clearly mark it as such so as to avoid potential confusion or contamination.
In my freshman year of high school, my English teacher drank out of her water bottle, but it wasn’t filled with water. She had a separate water bottle that she filled with alcohol for clearing chalkboards or whiteboard. She was okay after doing a spit-take, and taught us all a valuable lesson that day.
