Some people end up cleaning their dryer vents with the first thing they find in their house- a brush. However, if you’ve researched thoroughly, you would have realized that this can be a case of concern. Manually cleaning vents can cause a lot of damage. The vents can stretch or tear, due to which there will be excess lint buildup, and airflow will decrease. As mentioned above, this can prove to be a safety hazard as fires usually start in dryers because of lint. It could also lead to clogs, meaning that you’ll have to pay a ton to get it fixed later on.
