Aggi, I read somewhere not to use compressed air on a computer key board because it forces dust and dirt into crevices where it should not go. I have applied that same rule to the sewing machine. What do you think about this idea? Is it possible it could be driving the dust and fuzz someplace where it could cause damage? I am not sure about it myself, but decided to take the precaution. I have never had a repair on my machine that is close to 25 years old. We all follow our own rules and that is OK..Whatever works!
