@enrisanti, Greetings friend, we are very happy to have you in the Home Repair Club.

The Oster blender you are talking about is undoubtedly a powerful and durable machine. You are right that brush corrosion is something that happens over time, and it is important to keep the motor running smoothly. The explanation you give about carbon corrosion and the signs that warn us of the need to change it, such as sparks and a burning smell, is very clear and effective.

Advice In terms of advice, your content is very complete, but as mentioned, it would be great to include a demonstration video with written explanations to achieve the highest score.

Although our mentors are not mentioned, we hope you will mention us in future tutorial posts. It is still important to thank them for their support.

Thanks for sharing your knowledge; Greetings friend, we are very happy to have you in the Home Repair Club.
