I just use a clean dry cloth to wipe down my machines. I don't use any cleaning product because I am afraid the liquid will cause me heartbreak if it leaks into the machine. I'm interested to see what others are doing.

Wal-Mart carries a cleaner called Purple Power...you mix it with water to use even thought it is a liquid form....spray it on a soft cloth and then clean your machine. don't spray on the machine..I worked in a sewing machine repair and service and that is what we used. Hope this helps.

For my machines that have a plastic body I use a microfibre cloth that doesn't require chemicals. I wouldn't want to use anything that causes the plastic to turn yellow over time. For my metal body machines I squirt a tiny amount of clear window cleaner onto the cloth if necessary otherwise I do the same as above.

I use a paintbrush to remove dust all over the body. If the Plastic does not feel smooth I would use a very small squirt of all purpose furniture polish on a cloth and rub the machine. It is not liquid. It is the same polish I use to clean my marble tops and it makes it shiny and smooth. Have done this for a long time and has not seen any color changes (going yellow). I also cover my machines if not used. So they are actully just open when I use them.

I always use baby wipes, also on the inside, they pickup all the extra machine oil and dust, I cut apiece off, and push in corners with the sharp end of the machine brush...wendy

I have always just used a damp cloth to wipe over the machine housing but do like the answers below. Thanks for asking. Marian

For stubborn marks I use a magic eraser.

Thanks for asking the question! I picked up some good tips! Deb

I use one of the fuzzy on one side clothes you use for car windows. The other side is a very low nap. I dampen one corner with water. making sure to get any excess water out. Carefully wipe down plastic exterior. Use the low nap side to polish/dry off any dampness. It shines like new when done. On the rest I use a long natural bristle brush and a small flash light. this is to remove any dust or debris in the bobbin area.I also have a magnifying glass to help see in the dark spaces.I have a brother 2500d.
