Preventing plastic containers from staining??

I know buying new containers is a pain, but America's Test Kitchen did a plastic food container review and found these to be the best: https://www.amazon.com/Rubbermaid-Brilliance-Storage-Container-3-Pack/dp/B07D84R2HP/ref=sr_1_6?crid=39WGOUBAT2PG1&keywords=rubbermaid+brilliance+food+storage+containers&qid=1574087702&sprefix=rubbermaid+bri%2Caps%2C171&sr=8-6

They have the look of glass, but are super-light, BPA-free plastic. From the video looks like they didn't pick up any stains either
