Every single piece is removable, making this the most hygienic straw tumbler there is. All Resa Flip lids, straws, and interior components are top-rack dishwasher safe.
Most Resa Flip bodies are top-rack dishwasher safe, with a few exceptions. Check the bottom of the sleeve on your tumbler for washing instructions.
When washing your lids, remove the SlideSeal™ slider by pushing back further from the open position until it disconnects from the lid. With the SoftSip™ straw, ensure the nub on the straw assembly is facing you. Tilt the SoftSip™ straw piece to the left to disconnect it from the lid (for deep cleaning, pull the silicone straw piece off, as well). Turn the lid over and remove the ColdKey™ stainless steel straw by twisting with the tabs until the notch aligns with the vertical grooves; pull down to release the straw. For deep cleaning, the gaskets under the SoftSip™ straw piece and the cold key straw, as well as the sleeve, can also be removed.
