Minding The Details: Cleaning A Moldy Plastic Cup

Kids will be kids, and ours are no exception.  We bought a 6 pack of reusable plastic Rubbermaid juice boxes on Amazon to avoid the waste and cost of buying juice boxes for school and weekend trips. They are very sturdy and have held up well to frequent washing.

This weekend, we found one beneath the couch. It had held orange juice, so a tiny bit of the sticky sweet juice had coated the inside.

Who knows how long it had been lingering in there, but it had grown some mold on the inside. Each container was about $2.77, and we didn’t want to throw it out.

We first tried hot soapy water, followed by the dishwasher, but the mold was still there.

I scoured the internet and found this article for rice and baking soda. I also asked in the Non Consumer Advocate Facebook page.  The folks there suggested bleach, and one suggested vinegar. We were feeling a little tetchy about bleaching something the kids would drink from, so we decided to try the rice.

We added rice and baking soda to the juice box, and then filled with hot water and a bit of dish soap.

My trusty assistant was generous enough to shake the bottle for me. It took all of 2 minutes. She was disappointed when I would not let her drink the contents. The rice and baking soda served as a scouring agent, and scoured the mold right off.

I then filled with 50/50 vinegar and water to disinfect.

I ran it through the dishwasher and- voila!- it was clean and good as new.

It took me about 20 minutes of research and 5 minutes hands-on time, but we kept $2.77 in our pockets.
