Oprah's worth around $3 billion, but she's still pretty damn frugal when it comes to cleaning her undies.
We got Oprah in NYC and when we asked what she hates splurging on ... she was locked and loaded with a very candid tip about panties and hotel cleaners: DON'T DO IT.
Watch ... O's got a much better option, which might sound like she's bragging about her bank -- but actually makes solid cents.
The yarn about her panties in a French alley is pretty classic too.
