5.26 dome cleaning is done twice a year, as the dome can get pretty dirty with weather and all the trees

5.26 a simple mixture of dr. bronners sal suds, borax, and a small amount of bleach does the job

5.26 the best solution so far has been double-sided sponges (with a mild scouring side and a soft side) to scrub the dirt and old rags to wipe it clean

5.26 ladders, a long hose, and a tall person help get the crown scrubbed

5.26 all windows must be cleaned with soft cloths to avoid leaving scratches

5.26 back to full brightness by the end of the day
