Whitney Houston -- Family STRIPS Hotel Room to Thwart Looters

Don't count on finding a scrap of Whitney Houston death room memorabilia -- sources tell TMZ, the singer's family has meticulously stripped the hotel room where Whitney died to preempt would-be looters.

According to sources, the family has removed nearly everything from room 434 at the Beverly Hilton hotel that hasn't been bolted down -- including bed sheets, towels ... even bits of trash.

We're told the family is concerned about people trying to make a desperate buck off Whitney's death -- raiding the singer's hotel room and trying to sell relics of her passing ... whatever they might be.

It's unclear exactly what happened to the macabre souvenirs, but we're told they were all disposed of ... discreetly.
