SEATTLE -- Big changes are coming for the famous Gum Wall in Seattle's Pike Place Market.
For the first time in 20 years, the market plans to clean all the gum off the wall. Pike Place Market says a total scrub down is needed because of the sugar in the gum.
Market Theater's walls in Post Alley will be steam cleaned starting Nov. 10. The cleaning is expected to take multiple days due to the volume of gum on the walls.
Once the wall is clean, people will be allowed to put gum back up again.
The Gum Wall has grown to eight feet high and over 54 feet wide, with approximately 150 piece of gum per brick.
According to Pike Place, an estimated one million gum wads cover the wall.
The Gum Wall is located in Post Alley, under the market. It was started 20 years ago by people waiting in line for a late night improv show.
Before the clean-up begins, Pike Place is holding a contest for Gum Wall photos. You can find more information here.
