Thank you so much for info on Compressed Air. I had been thinking about buying a can, but won't now after hearing all the negatives. Not worth taking the chance.

I have use compressed air since it first came out. I use it in short spirts and follow up with my brushes and on occasion, q-tips. Have never had a problem. I can often get the lint that's sruck back in the corners that the brushes don't reach. Usually it's just enuf to dislodge a stubborn wad.

I have used the compressed air, but I also have the mini vac. Got mine at Target a few years ago. Also use both on my pc. Haven't asked my fix-it man. Never think of it.

I don't use canned air but I bought a small air compressor to blow out the bobbin area of my longarm machine and I also use it to blow out the bobbin area of my domestic machines. I know of other longarmers that do the same thing..my compressor has already paid for itself if you compare the price of canned air. Ive been doing it for nearly 7 yrs and have never had any problems as a result of using it.

I worked for 13 years as a service technician. One of the things I repaired was sewing machines. We used an air compressor with a nozzle to monitor pressure, to clean out most machines. For the hook area, when there was thread and lint massed up in there I used a very sharp pencil. The graphite helped to lubricate it and the lead was sharp enough to get out the lint, thread, etc. while being soft enough to break before it would scratch.
Today, I am retired and use canned air on my own machine and on others that I will work on for friends.
Just use common sense and you will not have any problems using it. I have never had it cause the lint to get stuck tighter.

i use canned air, but i'm careful not to shake it or it spits moisture. i also make sure that it is not pointed into the machine. i do use my mini attachments for my vacuum too to keep my machines clean. FYI my Dh told me that he's run a keyboard under water that someone spilled coke on. the water won't hurt it but the pop will stick it up but good. go figure!

I use air to clean the machine, then wipe it down. It usually blows the lint in my face, lol.

I just used it today. I know not to use it the computor but didn't know about my machine.
where do you get the mini vacumes? i might get one of those, to use instead.

I use the compressed air for every thing from sewing macines too computers to musical instruments to whatever is dusty. You have to be careful and not hold the air button down for a long period because the moisture will start too come out of the can and the can will get very cold and that moisture(although it has never caused me a problem) could cause things not too work right especially the more expensive sewing machines.

This is another of those topics where you have to do what you think is best. For me, I can't afford to take a chance.
