Here’s how often you really need to wash reusable water bottles

Stanley toters beware: You might need to wash your water bottles more often than you think.

A content creator who goes only by Jacey on TikTok revealed she only cleans her reusable water bottle, equipped with a straw, “once in a blue moon.”

Her viral confession amassed 2.7 million views and a chorus of critics who scrutinized just how hygienic drinking out of a rarely washed cup can be, claiming the creator was consuming “mold.”

“Girl math is never washing your water bottle bc if I only put water in it how is it dirty???” she wrote on the clip featuring footage of her contently sipping out of the reusable straw.

But instead of being met with allies, Jacey — who later admitted she does, in fact, wash her water bottle “once a week or two” — encountered a slew of criticism in the comments, as concerned viewers urged her to wash the bottle for fear of bacteria and mold growth.

“It will grow mold eventually trust me,” cautioned one user.

“Your backwash goes down the straw to the bottom and after awhile, it grows mold and the bottom will be slimy,” another explained.

“I did that too but then I looked inside the straw and almost threw up,” warned someone else.

“I did this the first couple of days I had my hydro and It straight up had mold on the sides WASH IT,” implored one person.

But others found Jacey’s admission relatable, blaming it on laziness or arguing that a simple rinse sans-soap will do the trick.

“How long are you guys leaving your water in there that it could grow mold I just refill it every day SORRY,” wrote one person.

“I haven’t cleaned mine for about… uhhhh…. like half a year,” confessed another user.
