How To Clean A Radiator With Baking Soda

In this guide, I will explain how to clean a radiator with baking soda.

A radiator is a metal box that sits beneath windows and distributes heat on the other side of the window. Radiators are typically made from steel or copper, but many people choose to paint their radiators with different colors to spice up their home’s exterior.

Radiators are not usually cleaned because they’re only used when there is an issue with heating in your home. However, it can be helpful to clean radiators if you have any issues with corrosion or rust buildup that could prevent them from working properly.

Radiator cleaning should take less than 30 minutes and requires only two ingredients: baking soda and water! To make this cleaner, mix one cup of baking soda into three cups of warm water. Pour this solution onto the radiator

How To Clean A Radiator With Baking Soda?

A home radiator is a very important component of your heating system. The metal pipes that carry hot water or steam throughout the house are routed through this device, which must be kept clear to work properly. There are several ways to clean a radiator with baking soda, but you have to find the one that’s best for you and your home.

Remove the Radiator Caps

Use a pair of pliers to pull up on the circular radiator caps. Use your fingers to pry them out if needed. Lay them aside, away from children or pets, who could injure themselves or swallow these pieces.

Fill Larger Radiators with Baking Soda and Hot Water

Pour a good amount of baking soda into a pan, bucket or other container. Fill the radiator halfway with hot water from the sink. Add about 1/4 cup of baking powder to the mix and stir it up using a broom or paint stirring stick.

Cover the Radiator

Put some old towels over the radiator as you pour in the hot mixture. The towels will catch the overflow, so you can reuse them with all-purpose cleaner or laundry detergent for several cleaning cycles.

Leave the Solution in the Radiator

Cover each of the radiator openings and leave it overnight to work its magic. The baking soda acts as a natural dehumidifier by absorbing water from the air in your home, which is one of the main causes of clogged radiators.

Drain the Radiator

Remove the towels and use them to wipe down any loose dirt or debris in the radiator’s nooks and crannies. Remove any excess baking soda with a vacuum cleaner. Dump the used water into an outdoor drain or a plant saucer. Rinse out the bucket and refill it with a fresh batch of hot water and baking soda.

Dump the Solution into the Sink

Pour all of this used solution down your kitchen or bathroom sink while flushing these fixtures with cold water to help the mixture travel through your home’s pipes more quickly. Rinse out the bucket before refilling it.

Add Clean Water to the Radiator

Pour about 3 litres of hot, clean water into each radiator opening and drain as much as possible using a radiator key or other hooked instrument. The hot water will help dissolve any remaining baking soda residue, which you can remove with a toothbrush or scrub brush made for tubs and showers.

Allow the Radiator to Dry Completely

Radiator caps can be tricky to replace, so you might want to take steps not to get any dust or debris inside these devices. Allow them at least 24 hours after cleaning before replacing each cap securely.

Will vinegar clean a radiator?

Yes. Your local hardware store may have cleaners specifically designed for cleaning radiators, but they are very expensive. A gallon of white vinegar is more affordable and just as effective. One reader had this to say: “I am so glad I’m not the only one who swore never to pay someone else to clean my house again!

I have found that a strong solution of white vinegar will clean a radiator. Fill your empty bottle with a mix of 50 per cent vinegar and 50 per cent water. Shake the bottle well, then pour it in all the openings in your radiator until they are full, leaving it for 30 minutes to an hour. Drain by opening the valves one at a time or using the hooked tool to open the drain screw at one end of the radiator.

Use a stiff brush or old toothbrush to clean any residue in each opening, then rinse with a little hot water and allow your radiator to dry well before replacing the caps.
