Cleaning an AVR after 10 Years using an item bought from an online shop

I decided to clean some of the electronics inside my room. I wanted to try some items that I bought from an online shop and see if they would work well.I found this AVR that we have been using for more than 10 years. I decided to clean this thing because that is where my pc was plugged. Upon opening it using the screwdriver it worked well, I was able to unscrew it with ease.

This was the blower that I used.

This was how dirty the AVR was just look at all that dust. Dust more than 10 years haha

I decided to use the blower to blow off all the dust. It was so fun to use it. It was very strong.

I used the brush to remove the dust that can't be blown by the blower. These items that I bought were very worth it.

Thanks for reading.
