1. Why should we clean the radiator?

After long-term use of radiators, dust, bacteria and impurities will accumulate inside and on the surface, which not only affects the heat dissipation effect, but may also cause allergies or respiratory problems. Here are the main benefits of cleaning your radiator:
| Cleanup reason | specific impact |
|---|---|
| Improve heating efficiency | Dust accumulation will hinder heat dissipation and heat up faster after cleaning. |
| Improve air quality | Reduce the spread of dust and bacteria, reducing the risk of allergies |

2. Steps and methods for cleaning radiators
According to recent discussions across the Internet, cleaning radiators can be divided into the following steps:
1. Preparation
Turn off the heating system and ensure that the radiator is completely cool. Prepare the following tools: soft brush, vacuum cleaner, rag, neutral detergent, old newspaper or plastic sheet (to protect the floor).

Use a vacuum cleaner or soft-bristled brush to remove dust from the surface of the radiator, especially from crevices. For stubborn dust, wipe it with a damp rag dipped in neutral detergent.
