We also now include a special 2 foam roller handle with pad and mini-tray for easier application to vertical and larger surfaces. How long will it take me to do? It takes about 45 minutes to prep a standard tub, and maybe an hour to properly apply the first coat. Then 4-5 hours of drying time and then a second coat.
Once a week, soak the steam unit in 4 inches of white vinegar for 10 minutes. After soaking, run cold water into the steam unit, plugging the bottom hole until the unit is filled. Uncover the bottom hole to drain the water from the steam unit. Continue to flush it with water until the water runs clear and you don't smell vinegar. Fill the water tub with tap water and a teaspoon of bleach. Drain and rinse the tub after 20 minutes.
