Tip for Screwing on Lids Easily and Safely: 
1. Place lid on top of mug.
2. Apply slight downward pressure and rotate counter clockwise until you hear a click and lid falls into place. 
3. Proceed to rotate clockwise to tighten down.

Avoid cleansers containing bleach, chlorine, and/or other harsh chemicals.  Always store the mugs and cups with the lids removed.  This will prevent moisture from becoming trapped in the mug or lid, which can lead to the growth of mold.  
 
To maximize the life of your new Contigo® product, we recommend hand washing because it is gentler than using the dishwasher as dishwashing detergents can be abrasive.  For specific information on whether your mug or cup is dishwasher safe, please read the Care & Use Instructions for your product.  All of our lids are dishwasher safe.

 1. Fill your sink with warm water and add dish soap or dish detergent. Agitate the water to form suds.
 2. Place the cup and/or lid into the soapy water so that it is completely submerged.
3. Allow the cup and/or lid to soak for several minutes up to several hours. For cups or lids that are especially dirty, a longer soak will be more effective.
 4. Use a soft cloth or sponge to wash the inner and outer surfaces of the mug. Use a bottle brush as needed to remove any residue from the inside and 
bottom of the mug. Use a smaller, pipe-cleaner-style brush to clean inside the lid, if desired. Refer to lid cleaning instructions below for additional brush

If hand washing does not get the mug or lid completely clean, or if the mug or lid develops stains or odors, we recommend the following:

1. Fill your sink with a solution of 1/4 cup of baking soda and 1 quart of warm water.
2. Place the cup/lid into the water so that it is completely submerged.
3. Allow the cup/lid to soak in the baking soda solution for several hours.
4. For stains or odors that persist after several hours of soaking, try soaking overnight in the baking soda solution and/or scrubbing with a small amount of baking soda on a clean damp sponge. Use caution to avoid scrubbing outside surfaces of painted mugs as this can remove the paint.
5. Rinse thoroughly and either towel or air dry.

• All AUTOSEAL® lids are dishwasher safe. 

If you would like to clean the lids outside of a dishwasher, you may use the hand washing methods listed above and you can try the following:

Always rinse the lid immediately after each use. Store with lid removed to allow parts to dry completely. Rinse drink spout immediately after use, prior to putting into the dishwasher:  

1. Turn lid so the underside is facing up and fill lid with hot soapy water.
2. Tilt the lid towards the drink spout while pressing the button to allow the soapy water to rinse through the drink spout.
3. Repeat 1 and 2 a few times for best results.

Rinse lid vent immediately after use, prior to putting into the dishwasher: 

1. Turn lid so the underside is facing up and fill lid with hot soapy water.
2. Tilt the lid towards the button while pressing the button to allow the soapy water to rinse through the vent hole.
3. Repeat 1 and 2 a few times for best results.
 

To clean the top of the lid

1. Use a non-abrasive sponge or brush head/swab to clean the drink spout in the open and closed position.
2. Rinse while pressing the button to allow the soapy water to rinse through the drink spout.

Clean the underside of the lid with a non-abrasive sponge or swish in hot, soapy water.

If desired, a small, pipe-cleaner-style brush, small arts and crafts paint brush, or a cotton swab can be used to clean the inside of the AUTOSEAL® mechanism.  Turn lid so the underside is facing up and fill lid with hot soapy water.  Run brush head or swab along the following areas to ensure complete cleaning:

1. Underneath and along both sides of the center plastic piece of the lid.  Reference "A" and "C" below.
2.  Along both the inner and outer walls of the threading.  Reference "B" below.
3.  The underside of the spout.  Reference "D" below.

Rinse repeatedly while pressing the button to allow the soapy water to rinse through the drink spout.
