racist dish brush?

There's this picture going around about a dish brush and people are saying it's racist. The original caption was something like "I'm gonna fight someone", so I thought it was a joke, but people actually believe that there's something wrong with it.
I personally can't see how it's racist though?
A lot of people are saying things like "they're saying black women should do all the work and cleaning"
But what do you guys think?
