Cleaning and Accessory Maintenance
Tank Cleaning (remove mineral deposits) – Do once a month
1. When the steam cleaner tank is cold and unplugged , use a13MM wrench and remove the
drain plug allowing water to drain from the system.
2. Remove the safety cap by pressing down on the cap and turning it slowly counter-clockwise.
3. Take 1 cup of vinegar and 3 cups of water together. Add this mixture to the steam cleaner tank.
Let mixture sit for 2 to 3 minutes, fill tank with clean water turn machine upside down over sink
and drain. Refill with clean water and rinse until all mineral deposits are rinsed out.
Drain Plug
VERY IMPORTANT – NEVER ADD CHEMICALS INTO THE TANK! Adding any form of chemicals or
fragrance to the tank will void the warranty and could result in malfunction or damage to the system.
For most jobs, you do
NOT need to use cleaners. However, for cleaning surfaces that may have an oil base
mixed with dirt, we recommend heat activated Vapormate (Available at www.homedepot.com or
www.ussteam.net ) cleaning agent, which is 100% all natural, and formulated for EXTERNAL use with the
steam cleaner.
Accessory Cleaning – Do after each time used
Always wash accessory brushes with warm, mild soapy water after each use. Get in the good habit of
cleaning brushes before the dirt dries on them. All accessories can also be cleaned in the dishwasher,
except for the flexible hose. Accessories can be sanitized by steaming them with the steam hose and the 1-
hole nozzle.
Water Conditioning
It is recommended to supply the steam cleaner with clean low mineral content water (distilled water) to help
prevent scale build-up. Even though the US Steam System is engineered to minimize scale formation, scale
development depends on the hardness of your water and the number of hours the equipment operates.
Most tap water sources are full of minerals, which form scale during operation leading to component failure.
Your water utility can tell you about the mineral content of your water. For optimal performance and
component longevity, water should have between 10 and 30 parts per million (PPM) total dissolved solids
(TDS) and should have a pH (acidity rating) of 7.0 or higher.
Using distilled water, especially in areas with hard tap water, will provide longer life to the unit,
higher steam capacity, and reduce maintenance requirements.
If you notice a reduction in steam production, check the unit for scale build-up. Heavy scale reduces the
unit’s ability to boil water, and may cause the boiler to overheat and burn out. (See “Maintenance” section
for information about removing mineral deposit build up.)
