Quick answer: a steam generator needs two kinds of cleaning. Descale the base regularly using its built-in system (rinse Tefal’s scale collector, drain Philips’ Easy De-Calc, or run Morphy Richards AutoClean) when the reminder light comes on, usually every 1–2 months in hard-water areas. Clean the soleplate when cool with a damp cloth and a little washing-up liquid, and never use scourers. Always unplug the unit and let it cool fully first.
Before you start
- Unplug the steam generator and let the base cool for at least 2 hours (the boiler holds very hot water under pressure).
- Work over a sink or a towel.
- Check your manual, because the steps vary by model.
Tefal Pro Express (scale collector)
- With the base cold, open the scale collector flap on the side of the base.
- Unscrew and pull out the collector.
- Rinse it under the tap to remove the scale, then refit it firmly.
- Reset the descaling light if your model needs it.
Philips PerfectCare (Easy De-Calc)
- With the base cold, hold it over a sink with the Easy De-Calc knob facing down.
- Unscrew the knob and let the water and scale flow out.
- Refit the knob and refill the tank.
Morphy Richards (AutoClean)
Follow the on-base AutoClean reminder: with the unit set up as the manual describes, run the AutoClean cycle to flush scale out. No cartridges are needed.
Russell Hobbs and others (anti-calc cartridge)
Rinse or replace the anti-calc cartridge as directed in the manual. Cartridges have a limited life in hard-water areas.
Cleaning the soleplate
- With the iron cool, wipe with a damp microfibre cloth and a drop of washing-up liquid.
- For residue, use a paste of bicarbonate of soda and water on non-coated plates, avoiding the steam holes. See how to remove sticky residue.
- Clear steam holes gently with a cotton bud.
- Steam over an old towel afterwards to flush any residue.
What not to do
- Don’t pour vinegar or descaler into the base or tank unless the manual allows it.
- Don’t use metal scourers or abrasive cleaners on the soleplate.
- Don’t open the boiler while it is hot.
Frequently asked questions
How often should I descale a steam generator?
When the reminder light comes on, typically every 1–2 months in hard-water areas or every 10 or so sessions.
Why is brown water coming out of my steam generator?
Scale and residue in the boiler. Descale it using the built-in system, then run steam over an old cloth until it comes out clear.
Can I use distilled water in a steam generator?
Check your manual. Many are designed for tap water, and some recommend a tap/distilled mix in very hard areas.
Should I empty my steam generator after every use?
Empty the removable water tank, yes. Philips’ steam generator manuals recommend emptying the tank after every use because standing water can grow algae and leave deposits. Do not try to drain the boiler each time: on Tefal and Philips models you open the scale collector or Easy De-Calc knob only when the descale light comes on, and only once the base is cold.
Why does my new steam generator leave white bits or smell on first use?
A faint smell or wisp of smoke on the first few uses is normal. Philips states that some parts are lightly greased during production and this burns off after a short while. White flecks are usually loose scale or mineral deposits flushed from a new boiler or from the water, so steam over an old towel until the output is clear before you iron anything good.
