Starting on Monday, Sept. 11, the Montgomery County Department of Transportation (MCDOT) will begin its semi-annual interior washdown to degrease and clean 21 County-owned parking garages in Bethesda, Silver Spring and Wheaton. The cleanings will occur on nights and weekends starting with Bethesda garages in September and concluding with Silver Spring garages on Saturday, Nov. 4. 

Some garages will experience partial closures during the cleanings, including select entrance/exit areas and ramps. The full schedule of garage cleanings can be viewed here. 

MCDOT performs spring and fall washdowns to keep garages clean and help keep grease, oil and debris out of local waterways. Regular cleanings also prevent deterioration from prolonged exposure to salt, sand, oils, gas, dirt, pollen and leaves. 

MCDOT contractors will do their best to perform work around garage traffic and parked vehicles and to post signs notifying customers of anticipated impacts.
