I put hot tap water and a little dish washing soap like dawn in it, put lid on. Then shake a couple times and depress the button and pour out the soapy water. Repeat with hot plain water to rinse. Works great!

I've had my kid's cup for about 3-4 years and have had to throw 2 away because the seal wore out. The inside of the lid and the rubber seal around the top of the cup can get gross, so they need to be washed well after each use. I use a baby bottle brush to clean the cup and the tiny brush that comes with it (the one used for nipples on a baby bottle) to clean the lid. For Coffee mugs you could try vinegar to clean the lid. I love these cups.

I've used the dishwasher without problem, except have to shake out some water after it's clean...the only problem I've had is losing one! Never had one break while I've owned it. Like the idea of a water pik, but think it's unnecessary.

Looking for new spill-proof mug but after reading all the comments on how to clean, the lid and it's parts sound very much like the OXO spill proof mug. LOVED my OXO mug for being 100% spill proof and kept my coffee hot for 6+ hours but the lid was a pain to clean. Unscrew the center, remove the two rubber rings and I would soak in very diluted clorox cleanup, then use toothbrush, pipe-cleaner and Dawn to get in to those difficult areas, then rinsed in hot water multiple times, then reassemble. Both seem like a hassle to keep clean for a spill-proof mug. May I should forget spill-proof and just try not to be clumsy with my coffee mug.

I, too, put hot water with a dab of dawn inside and screw the lid on, shake shake shake and open the button to pour out the sudsy water. I then unscrew the top and use q-tips to clean the grooves and bits of the lid. I have owned 2 of these mugs for a few years now and LOVE them. I tried using a bottle brush in the lid but couldn't reach the gunk well enough, hence the q-tips.

I sit my lids in hot, Hot, HOT (but not boiling) water with a scoop of OxyClean or 2 parts peroxide/1 part hot, Hot, HOT (but not boiling) water and let them soak for about 15 minutes. Make sure the water completely submerges the lid and maybe open and close the lid a few times while submerged. The oxy power eats away at any protein residue (milk, cream, etc.). Once this is done, rinse them really well. I do this every 1-2 weeks. Also, don't screw the lid on if either the lid or the container is wet/damp inside. This is a breeding ground for mold and/or stinky smells.I've had mine for about a year and have not had any issues once I started cleaning them this way.

If you go to the Contigo website they have a set of cleaning brushes you can buy. I haven't bought them, but they even show you how to apply them to clean the product.

The Lid does suck to clean so rinse while everything is still wet with clear water by putting the lid on, shaking vigorously and pouring it out while holding the button. Even with that, My drinks were starting to taste like dirt because of stuff collecting in the closure. I used a piece of wire to keep it open and put the top in the dishwasher which seems to have done the trick since it was able to get into all the nooks and crannies that aren't exposed or accessible﻿ when not held open.

There is a little piece of white plastic that connects to the underside of the top that keeps liquid from coming out unless there is suction. You can remove the white piece and then the milk free flows. I have forgotten to put the white piece back on several times after cleaning, then the milk flows everywhere.

I've had mine for a few months and have run it through the dishwasher multiple times (I generally hand wash all of my dishes) and mine are still looking great! Youtube directions on how to clean the lid and it's actually super easy to take apart and rinse.

In general, it is very easy to clean. Pop the top off, dump everything in the trash, and wipe it out. The only part that is sort of gross is the part under the water bottle. It gets sort of disgusting, but is still not difficult to clean - just sort of yuck.

Yeah. We dishwash the crap out of these. I like to give them a rinse after they've been through just in case there's any soap residue, but they can definitely take the abuse. Get a dishwasher nipple cage and you're all set. Be careful though, if you put them in the diswhasher with a big bowl of spaghetti and red sauce, you get orange nipples for the next few cycles. Great for halloween.

You really cannot clean it properly. I use only for the time my child has nasal congestion and throw it out after he is better. Between use during the time of nasal congestion I use antibacterial soap to clean the outside and then suck bleach water into it shake it around and let it sit for at least 10 minutes. These are great! Just throw them out after the child is well again. Hope this helps!

I clean mine semi-regularly FIRST by washing out with Dawn dishwashing soap & hot water, rinsing, THEN filling it with very hot water plus two denture cleaning tablets. I leave it fizzing for a couple of hours (or overnight), then rinse it well. This works well with all my thermal mugs, water bottles (glass, metal, ceramic, etc). I also soak the lids in the solution.

The packaging says "not recommended for dishwashers"...especially the lid liner, gasket liner and lid. You will find that this is pretty much self cleaning and does not really need to go in a dishwasher. I just rinse mine in warm soapy water and let dry.

I wash it all the time...nothing happens to the bottle...But I think the lid is not dishwasher safe at all. this is an awesome bottle if only the lid fits tighter and water doesn't leak if the bottle is not upright. Otherwise the stainless steel bottle is THE BEST :)

I noticed that the inside of the lid is corroding too, but I still use it because no rust is present. However, the corroding can be reduced by washing the lid at least once a week by hand, not in the dishwasher. Yes, it is safe to use them.

I use it on all cold liquids, I just let it soak if milk is used in it to get the milk out of all the nooks and crannies. :) I use a Dr. Browns bottle cleaner on the straw, looks like a pipe cleaner. Works great for the straw and the mouth piece.

I haven't had any trouble and i have been using glasslock products for years. I have never gotten mold on the lids. I run everything through the dishwasher between uses. Maybe they should practice safe food storage, you really shouldn't have anything stored long enough to grow mold....right??? Gross!! then you don't have to worry about it staining the container. Free advice &gt;&gt; Don't eat over their house ;)

I always wash both in the Dishwasher. I've had Randolph mugs for 2 years, and they're well used daily. The color on some of them is scratched and some bubble a bit (perhaps caused by the dishwasher) and on some the color is just wearing off. The surface of the Uncolored ones are still perfect. Also, a couple of them are dented where we've dropped them on hard floors. But they all still work just fine. I just remove the lid and open it, then toss both parts in the top rack of the dishwasher. Have also put the base in the bottom rack too when there's no room up above.

I rinse mine off in hot water as soon as I pour the milk out and set it on a dish towel to dry. Never had to put it in the dishwasher. It is coated on the inside. I love mine. 1 cup of microwaved whole milk, pour in, put the lid on and push the handle up and down about 30 times lift off, pour in cup of pre sweetened coffee, rinse insert and wash the pot by hand. Enjoy. It is the best. Nothing to break. You can also make foaming hot chocolate.

We normally rinse it after each use. To clean more thoroughly we use a vacuum bottle brush we bought from an ACE Hardware store. This is just a long handled round brush. We also regularly rinse the lid; note the lid can easily be partially disassembled so you can thoroughly wash the inside areas of the lid with soap and water. On the lid, under the handle of the valve for pouring, you can see a little round tab sticking out that might seem to serve no purpose. Push firmly up on that tab (not on the valve handle) and the round cap on the top or the lid, kind of like the lid of a big pop-top pill bottle. When you are done, just line the top with the bottom and snap them back together. We normally rinse it after each use.

We have had ours since September and whether you are a teenager or and adult you have to try pretty hard to get the interior of the lid dirty. Otherwise, remember that there are electrical connections that even though they are battery operated and of no real danger they will short out should they get washed. All of this is visible so you shouldn't have a problem knowing what to do. Maybe if you give the responsibility of clean to the teens they will be more careful with the way they use the trash can.
