Updated . How we count
Share of shoppers who stated an outcome for cleaning. Ranked by the lower bound of a 90% confidence interval, so a product needs both a good share and enough reports to rank high.
Both Ello cups draw frequent cleaning complaints: 28% of Ava reviews and 26% of Jones reviews say they're hard to clean or grow mold. Simple Modern reviews raise no such complaint.
Praise and complaints are the points shoppers repeat most, shown as a share of each product's counted store reviews.
Simple Modern
Best for fuss-free daily washing
Washing it was no trouble for 15 of 15 shoppers who brought it up, and none mentioned mold or trapped gunk. 21% also say it holds up well over time.
Contigo
Mostly a quick wash: 12 of 16 shoppers said this travel mug cleans up easily. The other 4 said gunk or mold built up, and reviews copied from Contigo's site come in at 5 of 6, which we show but don't count.
BruMate
Fewer shoppers talked about cleaning this straw tumbler (9), and 7 of 9 found it easy. 10% of its reviews say it's hard to clean or gets moldy, and reviews copied from BruMate's site are less upbeat at 3 of 5, which we show but don't count.
Ello
This travel mug drew the biggest group of cleaning reports (20), and it's close to an even split. 11 of 20 said it was easy to clean, while 9 said gunk or mold built up.
Ello
Cleaning is the main complaint: 11 of 16 shoppers said it was hard to clean or got moldy. Reviews copied from Ello's site are all positive (6 of 6), which we show but don't count.
The 5 products ranked here carry 3,408 reviews at Target. We read the newest reviews of each product (up to a thousand per listing), kept the ones that talk about cleaning, and counted up to 40 per product, posted between Aug 2020 and Oct 2026.
A review counts only when the reviewer used the product themselves. We drop reviews written in exchange for a free product or a sweepstakes entry (1 on this page), and products that are no longer sold.
Target also shows reviews first posted on brands' own websites. We show them on product cards but never count them, because brand-site reviews run more positive than store reviews of the same products.
Because we searched for the problem, people who had it are overrepresented. Compare products with each other rather than reading a share as your own odds.
We count what shoppers report. Nothing here is safety advice: use heaters, fans and other appliances as the maker's manual says.
Amazon buttons appear only on products that most shoppers here say fix the problem (at least 60%, with enough reviews to trust it). Everything else gets no buy link.
An AI model labels each review against a fixed list of points, and we spot-check the labels before publishing. We publish counts, never the reviews themselves.

Take the lid apart as far as it goes and wash each piece, the rubber gasket included. Let every part air dry before you put it back together, since moisture trapped under the gasket is where buildup starts.
