How to Prevent Limescale Build-Up?

There are many things you can do to ensure that limescale does not build up in your steam generator iron and cause any blockages in the steam holes of your iron. Prevention is better than cure. Here are some tips to help prevent limescale build-up:

Tip 1: Be cautious about the type of water you are using. This should be distilled water or demineralized water. This type of water is purified and won’t contain any minerals. You can buy distilled and demineralized water at a supermarket or a drug store.

Using water from the faucet will mean you need to descale your iron much more frequently. There is an issue, however, as specialized water can be expensive. If you do not wish to purchase water often, an alternative is to use a water filter. You’ll need to get one that removes minerals as a lot of them don’t do this, so you’ll need to double-check.

How to Descale a Steam Generator Iron?Tip 2: Keep the soleplate of your iron clean. The steam holes on your soleplate can easily be blocked by dust residue. Limescale can increase when water is blocked in the steam holes. You can remove the dust particles on the soleplate with a soft sponge once your iron has cooled down. This will also prevent you from having to descale your iron regularly.

Tip 3: Use the correct temperature when ironing your clothes. Ironing your clothes at a temperature that is not suitable for the type of material that you are ironing will cause small bits of dust to melt on the soleplate.

This causes water to build up in the steam holes, which then leads to limescale. Ironing your clothes at the correct temperature will prevent this from happening as often. All clothing items have a label attached to them that indicates the temperature at which they should be ironed at. Clothing with prints on them requires special attention as it can easily melt due to the material that it is made from.

Tip 4: Empty the water tank. Once you are done ironing, and there is still water remaining in the water tank, make sure to empty the water. Storing water in the water tank can cause deposits as the water evaporated.

Make sure your steam generator iron does not have any water in it when it is stored for long periods. If you use your iron every day, then this will be less of an issue.

Replacing Your Steam Generator Iron

As with any type of electrical appliance, there will be a time when not even regular maintenance is going to solve its issues. If you go through these cleaning processes and still have an issue with your iron, then it’s probably worth getting one of the best steam irons available on the market.

If you are looking for a new steam generator iron, check the Rowenta DG8520 Perfect Steam model that offers 1800 watts of power and 5 bars of pressure. While that is great, it may be a little over your budget. If so, the PurSteam 1700W Steam Iron is a brilliant affordable alternative.

This could ultimately save you time and money, as your iron will last longer, and you won’t need to be spending money on repairs or buying a new iron every few months.
