During the cold months, radiators are essential for maintaining a warm and comfortable environment. However, with constant use, they accumulate dust, grease, and debris that reduce their efficiency and affect air quality.
Proper cleaning not only improves the performance of your heating system, but also prolongs its lifespan and prevents unpleasant odors.
Below, we explain how to efficiently clean a radiator with professional cleaning products that really make a difference.
Basic steps to clean a radiator correctly
-
Gather the right products
Before you begin, turn off the radiator and let it cool completely.
Prepare everything you need: disinfectant detergent, degreaser, microfiber or PVA cloths, a mop or duster, and cleaning gloves. -
Protects the floor and wall
Place a towel or absorbent paper under the radiator to collect dust and moisture. -
Removes surface dust
Use a mop or duster to remove visible dirt, going between the cracks and along the back. -
Vacuum the inside of the radiator
If you have a vacuum cleaner with a fine nozzle, run it over the base and inside to remove accumulated lint. -
Clean with a damp cloth
Dampen a microfiber cloth with warm water and a little all-purpose cleaner. Wipe gently to avoid damaging the paint. -
Apply degreaser to difficult areas
In kitchens or greasy environments, use a professional degreaser. Let it sit for a few minutes and wipe it off with a clean cloth. -
Clean the valves and connections
Wipe the valves and sides of the radiator with a damp cloth. Avoid dust or metal residue from accumulating. -
Dry all surfaces thoroughly
Using a dry cloth or towel, remove all moisture to prevent rust. -
Clean the wall and the floor around it
Take the opportunity to wipe the surrounding area with a floor cleaner or all-purpose cleaner. This will prevent dust from settling again. -
Use compressed air or a dryer on cold mode
If there are hard-to-reach areas, compressed air or a cold dryer can help dislodge dust without damaging it. -
Avoid abrasive products
Do not use metal scouring pads or products containing ammonia or strong solvents; they could damage the radiator's finish. -
Controls the humidity of the environment
Excessive humidity can lead to mold. Use gel air fresheners or moisture absorbers to keep the air clean. -
Refreshes the environment
After cleaning, apply a professional air freshener from La Corberana to leave a lasting feeling of freshness. -
Maintain a regular cleaning routine
During the heating season, clean your radiators once a month to maintain their efficiency. -
Bleed the radiator once a year
Open the valve to release accumulated air before winter. This will improve heat circulation and reduce energy consumption.
Methods to clean a radiator efficiently
1. Manual cleaning with cloths and multipurpose cleaner
The most common and effective method for regular maintenance.
It consists of cleaning the surface of the radiator with microfibre or PVA cloths moistened with disinfectant detergent or multi-purpose cleaner .
Allows you to remove dust, grease and light residue without damaging paint or metal.
Ideal for homes, offices and frequently used spaces.
2. Cleaning with compressed air or hairdryer in cold mode
Perfect for radiators with narrow or hard-to-reach gaps .
Compressed air (or a hairdryer in cold mode) expels accumulated dust from the interior and rear without having to disassemble the radiator.
Afterwards, simply wipe with a dry mop or cloth to collect the loose dirt.
3. Vacuuming
A quick and very hygienic method.
Using a fine nozzle or a small brush , the vacuum cleaner removes dust and lint from both the outside and inside of the radiator.
It is ideal for homes with pets or in environments where a lot of dust accumulates.
4. Steam cleaning
Recommended for deep cleaning.
A steam cleaner removes grease, dust, and bacteria without chemicals, using only pressurized hot water.
It is effective and environmentally friendly, although it must be used with care to avoid damaging old paint or sensitive joints.
5. Cleaning with professional degreaser
If the radiator is in a kitchen or area where grease accumulates, this method is the most effective.
Apply a concentrated degreaser from La Corberana , let it sit for a few minutes and remove it with a damp cloth.
Dissolves grease without damaging the finish or leaving residue.
6. Exterior cleaning with a duster or mop
Ideal method for frequent maintenance .
Use a microfiber duster or an extendable mop to remove dust from the exterior of the radiator once or twice a week.
Prevents dirt from accumulating and makes deep cleaning easier later.
7. Cleaning with disinfectant detergent
Perfect for radiators in hospitals, schools, gyms or high-traffic areas.
Use a professional disinfectant detergent , formulated to eliminate bacteria and viruses, ensuring a healthier environment.
Apply with a damp cloth and then dry with a clean cloth.
8. Eco-friendly cleaning with vinegar and water
For those who prefer a natural alternative, you can clean with a mixture of warm water and white vinegar (equal parts).
It is a disinfectant, eliminates odors and leaves no chemical residue.
However, it does not replace the effectiveness of professional products when there is persistent grease or dirt.
9. Cleaning with washable protective covers
Some homes and businesses use decorative or protective covers for radiators.
These covers can be removed and washed, reducing dust buildup and making general cleaning easier.
It is a preventative rather than a corrective method, but it is very useful for keeping the radiator clean for longer.
10. Comprehensive professional cleaning
For old, rusty radiators or those with a lot of dust buildup inside, a thorough professional cleaning is ideal.
Cleaning companies use specific products, industrial vacuum cleaners, and steam equipment.
At La Corberana, we supply the chemicals and accessories used in this type of cleaning, both for professional and advanced domestic use.

Conclusion
Each method has its usefulness depending on the type of radiator, the environment and the frequency of cleaning.
The key is to combine frequent maintenance methods (duster, vacuum cleaner, cloth) with deep cleaning methods (steam, degreaser, disinfectant detergent).
With professional cleaning products manufactured in Spain by La Corberana , you can keep your radiators in perfect condition and improve heating efficiency, air quality, and the overall hygiene of your space.
