RP1712 Moistening Brush - Discontinued
The manufacturer no longer offers this brush. Fits Marsh brand machines including the Electra, Ultra, 4BT, 5HT and all other machines previous to the year 2000.
Make sure to clean the moistening brush weekly with Dawn or Ivory dish washing detergent. Avoid using soaps that contain hand softeners as they usually contain oil. Replace the brush every 2-5 years for best results.
