PITTSBURGH -- Target 11 investigators Stacia Erdos and Rick Earle went undercover and discovered local hotel workers not following correct procedures when cleaning glasses found in hotel rooms.

Target 11 set up hidden cameras at three Pittsburgh area hotels.

The three hotels were the Radisson in Monroeville, the Sheraton Four Points at the airport and the Marriott Springhill Suites in West Mifflin.

At the Radisson in Monroeville lipstick and toothpaste stained glasses were left in the hotel room to be cleaned.

The hidden cameras captured the housekeeper spraying a pink liquid into the glasses, rinsing them in the bathroom sink then drying them with a towel.

She then used the pink cleaner to finish cleaning the rest of the bathroom.

The lipstick was still visible on the glass after they were cleaned.

The glasses never left the room

Target 11 investigators showed the video tape to Allegheny County Health Director, Dr. Bruce Dixon.

Dixon didn't like what he saw.

"We'd like to see them washed and dipped in sanitizers," Dixon said.

He also said his biggest concern wasn't the spray used, but what could still be on the glasses.

Dixon said, "If it were infected fairly recently you could get E. coli , staph infections, you could get several viruses."

At the Sheraton Four Points at the airport hidden cameras rolled as the housekeeper only rinsed the dirty glasses in the sink with running water, and then dried them with a dirty towel left in the room.

She continued to use the same towel to wipe down the rest of the bathroom.

Dixon said, "Yeah, I think this is much more likely to result in problems for someone who uses them. That couldn't have gotten rid of any kind of germs on that glass."

The county health department inspects restaurants and if this had been done in a restaurant Dixon said they would be fined.

The third hotel tested was the Marriott Springhill Suites, which was the only hotel to actually clean the glasses correctly.

Housekeeping collected all the glasses and removed them and replaced them with clean glasses.

While none of the hotels would talk to Channel 11 on camera, Rick Strunk, the Executive Vice President of the Greater Pittsburgh Hotel Association did.

Strunk said, "That obviously would not be considered a good practice in our industry."

Strunk says the industry standard is to wash all glasses in the dishwasher.

"I think remedial action should be take place with the employee to make sure they're doing their job properly," Strunk said.

And the Radisson did take action.

The housekeeper who sprayed a pink liquid into the glasses no longer works there and the firm that supplied her has been terminated.

The Vice President of Operations said, "Absolutely in violation of our hotel's standard operating procedure."

The General Manager of the Sheraton Four Points, where the glasses were wiped with a dirty towel told Channel 11 over the phone, "It is our policy to take the glasses out of the room and put them into a dishwasher to be cleaned."

Dixon said there are no guidelines or laws in Pennsylvania or Allegheny County regulating how these glasses should be cleaned or sanitized.

But other states do have guidelines and the health department checks to see if restaurants sanitize their glasses.

When asked if he thought the health department should inspect glasses at hotels, Dixon said, "I don't think there's any question about that and we're going to raise that issue with our housing division and perhaps put some rules in place that requires that."
