I don't have wood mounted stamps anymore, I removed them from the block and then added cling foam to them. Never had a complaint about it. Recently I purchased a couple soon-to-be retired rubber stamps from Lili of the Valley (in the UK) and they are unmounted rubber (which I knew). I was planning on putting them on cling foam, but am rethinking that idea. I have all my stamps (clear and rubber) in Avery Elle stamp pockets and LOVE those. But some of the rubber sets are too thick for the pocket and it is causing them to split open.
I also use my mini Misti for 99% of my stamping, and love it.
I know there used to be a product you could put on the back of the rubber stamp to have it cling to a block without the foam. Is there something different I can do, so I can take my rubber stamps off of the cling foam?
Here is one of the stamps I got from Lili of the Valley.
You can use a repositionable glue directly on the rubber - Alene's Tack It Over and Over is good, and so is Tombow Mono Multi (white bottle with green caps). I've been using the Mono Multi because it's my go-to for most things that I use liquid glue for, so I usually have a bottle nearby. Just coat the back of the stamp with a THIN coat and let it dry, and it works just like the cling foam.
I know that there are other repositionable glues that people have used with good results; you can also use Scotch poster tape; I also remember there was someone who just swiped the back of the stamp with some lip balm. There's also a cling cushion that I can't remember the name of offhand, that you can apply to your block instead of the stamp. I prefer the repositionable glue because then the stamps will stick to my storage sheets as well as the blocks.
warrior1991 - Most of my background stamps still have the cushion on them; I never mounted them to the wood blocks in the first place and just coated the back with the repositionable glue. Sentiments, it depends. I've found that as a general rule, the smaller stamps actually stamp better without any kind of cushion. It's almost like the cushion makes them kind of unstable. If I have a set that comes with cling cushion on them, I don't take that off. It's only the stamps that I'm taking off wood blocks that I sometimes remove the cushion entirely, or stamps that I've purchased that are bare rubber (no cushion or cling) that I don't necessarily add cling cushion.
As far as if I decide to sell or give away a stamp/set? Hasn't happened yet. Having stamps off the wood blocks is a mixed blessing/curse. They don't take as much room to store, so there's less incentive to weed them out.
I remembered hearing years ago about microwaving the stamps for a few seconds to loosen the foam. is that still something to do? Some foam is not coming off the stamp.
Microwaving can help; so can shoving them in the freezer for a bit. I liked the freezer better, because I could put a big bunch in there and take out one at a time to work on, while the rest stayed cold. I've used Un-Du on some that the microwave/freezer didn't work with. But once in a while you come across some that are held together with some kind of insane adhesive that was apparently developed for the aerospace industry and doesn't want to let loose for anything. And unfortunately, the only way to find out that you're dealing with this demon adhesive is when the foam comes off in chunks, so now you can't just say "oh, I'll leave the foam on this one". Those required scraping with some kind of plastic scraper and then rubbing at the remnants with my thumbs.
Thank heavens I didn't have many of those.
If, by chance, you have any old TAC sets, with red rubber cushion - don't take those off the cushion unless you absolutely have to! The adhesive on those is some of the stickiest stuff I've ever seen and it has reinforcing threads in it (almost like the sticky side of duct tape). Un-Du works on those, but you end up with a heck of a mess in the end; sticky stuff and sticky threads all over the place, and it's a challenge to keep it from transferring onto the working side of the stamp.

cbet and scrapnnana Do you take the cling off of the sentiment stamps too and from background stamps?
If you decide to sell or give away a rubber stamp/set later, do you add cling back on or it goes as it is?
I took all of mine down to the bare rubber. I keep my stamps. All of them. Having them down to the rubber makes them easy to store and to find, even though I have more than I am willing to admit here. I keep them in the old PSBs. I can look through my entire, huge collection very quickly. I store certain types together (such as fall & Halloween in one binder, Christmas in another, florals in one, etc.). That helps.
cbet how long do you have the stamps in the freezer?
Sometimes for 15-20 minutes, sometimes overnight if I got caught up in another project and forget I was working on them. I did put them in plastic bags, figuring that would keep the rubber from the drying effects of whatever keeps the freezer frost-free.
I watched a couple YouTube videos about using a heat gun to soften the adhesive to get the foam off. So far that is working. But I still have some stamps that the foam came off, but the adhesive is left behind. Would putting the stamp in boiling water help with removing the adhesive, since the Un-do doesn't work for that on many of them?
Does Un-do get old? On the bottom of the back label it says DATE:020109
On many stamps, the foam comes off, but leaves all this adhesive behind. Un-do does not take it off. Suggestions?
I used an adhesive eraser and lots of elbow grease.
I would not boil rubber stamps. Too much heat can ruin them. I have some by one company that kind of melted, and I am not sure why. It was in a room that got very warm in the summer, but not that warm!
