LAS VEGAS (KTNV) - What is with the dirt on the Luxor pyramid on the Las Vegas Strip?
A viewer reached out to 13 Action News asking why the cleaning crew hadn't gotten the grunge off the windows.
A MGM Resorts International spokesperson told us the summer months certainly present a challenge in maintaining the pyramid's dazzle. The extreme heat combined with the rain limits the amount of time window washers are able to be out there clearing the dust.
MGM says they've actually increased the amount of cleaning in recent years but it's always a continual process.
