Frequently Asked Questions
Are disposable insulated cups safe to use on a moving boat or RV?
Disposable insulated cups offer convenience and a good heat barrier, but they are only spill-resistant when paired with the correct lids. For underway use, select lids that lock or snap on firmly and choose low-profile cups that sit securely in cup-holders; avoid tall, narrow cups that tip easily.
How do I prevent stainless steel tumblers from smelling like coffee or tea?
Regular cleaning with hot water and soap helps, but for stubborn smells use an effervescent cleaning tablet or soak per the manufacturer's instructions. Keep lids open to air-dry and store tumblers inverted or with vents to avoid trapped moisture that leads to odors.
What size tumbler fits RV and marine cup-holders best?
Measure the diameter and depth of your cup-holders. Many cup-holders accept 2.25–3.5 inch diameters; compact 12oz stemless tumblers and 4–8oz insulated paper cups are typically cup-holder-friendly. Lower-profile stemless designs are less likely to tip in rough conditions.
