How do we remove erasable white board marker from the apollo screen?

Are you asking about free motion quilting (FMQ)?

If so, you need a darning foot of some type (a foot that does not press the fabric to the sewing surface).

You need to drop the feed dogs (or if your machine does not have that capability, a feed dog cover that probably came with your machine and set the stitch length to zero).

Then, add lots of PRACTICE!!! I like to draw designs on a white board with an erasable white board marker... The more fluid you can become, the better experience you will have with FMQ.

A whiteboard is a non-electronic variation of the traditional "rewriteable" schoolroom blackboard, but is white instead of black and of a material that can be written on with colored markers (known as dry erase markers). Dry erase markers are easier to erase than the chalk used on a blackboard (which sometimes requires a wet rag for thorough erasing).

there is a liquid called stoko slig which is used to remove permanent marker they are on the web i think they based in stafford hopes this helps

Correct, that board is toast. The is the one thing that any circuit board can not handle is lightning strikes. Buy a new one.

Try pledge or hand sanitizer let dry before using again pledge or household polish works best. Good Luck

As I already printed several hundred CD/DVD the leading marker on the tray was badly marked. Tried to clean it with an eraser but I got very bad result. I tough I could paint it with some white paint but instead I use micro correction tape and white the marker. I had it working for 10 CD in a row, not bad for a cheap patch.

Where can I order a new CD/DVD tray?

Here are some solutions to consider. Try in an inconspicuous place first.
1) Use a clean WHITE pencil eraser. Yes WHITE pencil eraser. Some people use a pink eraser and then a white eraser over that for faster removal. Wipe residue off with a damp cloth.
2) Use White Petroleum Vaseline Jelly over the stratches. This may have to stay on an hour before wiping off.
3)You may also get commercial LCD scratch removers on the 'net.

An LCD screen should only be cleaned by using a damp(not wet) with water microfine cloth. Never use household cleaners of any kind.

use marker erase fluid or any quality cleaner product
just remember that it is a LCD screen so don't press hard when removing the mark

try and write over it with a dry erase marker. I know that if you write on a dry erase board with a permanent marker then completely cover it with dry erase marker then erase it it will remove it.
