How is the spray cleaner when used on dry erase marker that's been left on the whiteboard for a long time?

I have found through the years, that this Expo spray cleaner is the best when it comes to eliminating old marker. I've not had any issues with the cleaner removing any dry erase marker, no matter how long it has been on a whiteboard or a dry erase surface. I will just say it does not remove permanent marker, though, nor does it remove dry erase marker from a different type of surface. A fellow teacher once mistakenly wrote with a dry erase marker on a projection screen and this did not work to remove it. But if you use it for its intended purpose, it should work great.

It takes it right off assuming it hasn't already been erased once. On a whiteboard you will always end up with some background smears if you don't spray and wipe it often, but the Spray works very well. I have heard Windex does the same though and that may be the cheaper rout.

Yes, this basically has 3 different ways for kids to use it. The white board is for the dry erase markers, and the other side is for chalk. You can then roll the paper down to use and the board behind it then would be a type of hard easel board for the paper to rest against. But if you don't have any paper. you still have a chalk board and dry erase board. Now if you are talking about painting on the dry erase board, I would make sure I used only washable paint and try it on a little area. You may also want to make sure you do not leave it on for to long it may cause some stains. If that does happen you could try a mixture of bleach and water. I hope all this helps.

1st--I haven't ever labeled the container.....I know what's in it and if it's useable by appearance and feel/smell. BUT I imagine a "dry erase" marker pen, as used on white boards, would work.

We use that expo dry erase spray and that works out pretty good. Doesn't erase to well without it...

I have sprayed it with all purpose cleaner and used paper towels a few times. It was colored on with marker and I used the scrubbing side of a lysol wipe and the marker came off and did not damage the surface at all. It is durable.

It will remove almost anything from anything. :-) The only concern might be the surface of the whiteboard. Some of the whiteboard surfaces aren't made of the best materials and this product might damage it. Maybe try it on a small corner of the board to test it out. I've used this cleaner for years for all sorts of things including automotive, motorcycle, and even that really tough two sided backing they use to hold emblems on cars. It works great. Sometimes you have to let it soak a minute or two or give it a couple tries if it's really thick stuff.

The liquid chalk markers work great for this board. I used them the whole school year. I also used the plastic covers because the chalk is not weather proof. They clean off easy with water, mild cleaner and a rag.

Hi, Thanks for your question. Many of our customers are using our markers on chalk paint with success, however we do not recommend doing so. The reason being is that chalk paint - and all painted surfaces - are porous. This means the surface has microscopic holes which will allow ink to seep into the pores. Once you try and wipe the ink off a chalk painted surface, you may find it leaves a faint mark. Generally this mark can be removed using Windex, an ammonia based cleaner, or a lot of people have had success with Mr. Clean Magic Erasers, which are designed for removing marks off walls without removing paintwork. Given the variability of different surfaces and different brands of chalk paint, we would not recommend using our product on such a surface in case you experience issues with its removal. Other porous surfaces which should be avoided for the same reason include wood, concrete, & tiles. Also if using on a chalkboard, please check to ensure it is a solid slated chalkboard. What you will find is that if the chalkboard has a soft wood backing (often pine or similar), then it is most likely painted with chalk paint which may cause the above issues. Manufacturers of chalk boards often do this in order to save cost, and as you will appreciate whilst we guarantee the performance of our markers, we cannot guarantee all chalkboard surfaces are safe given there are so many different brands and types. We trust this is of assistance. Regards, Paul Davidson Chalk This Way

- I don't believe the residue of the markers will ruin new carpet; however, what might happen, as it did with me, the marks will not erase. The dry erase marker will actually permanently stain the area you tried to make dry erase. It is likely you will have to paint over the dry erase paint with the original room color. A better option is to just purchase a large dry erase board. You can purchase them at Wal-Mart, ect. To get a huge dry erase board for a reasonable price, check out Office Depot. It will cost more than the paint, but you go the route I did with the paint, the huge dry erase board will be less expensive. The dry erase paint is an enormous mistake. - I don't believe the residue of the markers will ruin new carpet; however, what might happen, as it did with me, the marks will not erase.

I used it on a whiteboard. It has been there for about a year, and I just peeled off a piece and there was no residue. Hope this helps :)

We use on chalkboard painted menus. It wipes off fairly cleanly. Over time, a residue builds. If the surface is very shiny, you've got a good chance.

To be honest, I haven't had a problem with any brand including dollars stores. Eventually it will get dirty like any whiteboard so i end I end up cleaning with that expo solvent stuff but the important thing is to figure out which side is the erasable side and which is not. Sounds like it would be obvious but I've mixed them up twice now so check before you use the paper!

They are also dry erase crayons now, but you need to use a spray to clean them off nicely.

There is a wet marker you can buy from Michaels or any place like that for like seven dollars or so that goes on wet and drys in a few seconds. Wipes off with a damp paper towel. Works fantastic, is very precise and crisp. I love my chalkboard and the markers are the way to go.

Yes. I am a teacher, and I go through boxes of these every year. Like Tom said below, it depends on the surface you have. The main whiteboards we have on the wall are pretty good for up to a few days. Anything left on after that will have the custodians asking if you used a permanent marker. The Quartet board I got from OfficeMax won't wipe off without cleaner no matter how hard I pray. Our DrawIt wall works the best surprisingly, I leave things on it for months at a time and I don't need anything. The glass works well too, but you won't get the vivid color you get on the wall, which is the only things the students at the back can see the colors on. Yes.

If used on an erasable "white board" it doesn't leave residue. I haven't used it on other surfaces.

if you have chalkboard paint that is painted on a wall and the wall behind the paint is porous (like drywall) you may have trouble removing the chalkers. Also if the backing on the chalkboard you use is porous, you may have issues with it erasing as well. I suggest that you test the chalkers on an inconspicuous spot and leave it overnight before using them on a large area.
