[Solved] How to "dissolve" the old, "sponge" double-sided tape?

For many years, I had roller shutters installed in my apartment, with side slats glued to the glazing beads (for better blackout). For some time, the blinds not only fell apart, but did not suit the household members. I decided to disassemble them and replace them with pleats.

The problem arose with these dimmer bars. They were of good quality (assembly quality was also good) and were stuck on a thick, "sponge" double-sided tape. After being torn off, the tape practically remained - in the form of a "sponge". I carefully scraped off the remains of this sponge. It's not all gone and there's tape glue underneath - I treated it with chemicals:
- a preparation for removing stickers
- WD40
- extraction diluent
- and even a nitro thinner

It barely comes off, only after stubbornly rubbing it and rubbing it with a rag. I grumble, and I won't clean it. Anyone have any idea what else I can do with this? I attach photos 1- before scratching, 2 - after scratching, 3 - after chemistry.

I don't know on what basis it is based.
In my opinion, alcohol based reagents should do the trick.
It was a "good" idea with this WD.

Some standard from the market for PLN 15.


I've already searched the entire internet and many people recommended WD40. Nitro advised me against it, but nothing would help me, so I even decided to try it. But I am still standing still: /

And that is why such "effects"
Buy a decent dedicated spray, not some water-based crap and additionally expensive. Must contain solvents.

Are you saying it can handle it, and gasoline and nitro sucks ...?

Spirit 95% is doing well.

If it does not come off with an extraction solvent or nitro - then alcohol or acetone remains, or a gel remover for old paint coatings may cause the tape to "swell" and it can be removed with a plastic spatula (so as not to scratch the frames).

You have to be careful with everything - it's best to make a gentle sample, I was washing the stickers with acetone from the windows and nothing happened with the plastic, but the nitro was dull.

Try some mayonnaise again. Lubricate and wait 24 hours until it turns yellow.

Of course. Gasoline is good for degreasing and evaporates quickly, as does nitro, and the solvents in sticker remover are slow-evaporating hydrocarbons that stay longer on the surface of the adhesive, dissolving it. After covering with the remover, wait a few to several minutes.

spirit isopropanol
Acetone
nail polish remover
Orange acid

If the glue is still sticky, stick a piece of cloth which is soaked with the above chemicals and then wiped with a cloth.

You can try to stick the silver MacGyver tape, press it well and tear it off after a while

In the company, we often struggle with these sponge tapes, they have various adhesives and some have to be wiped off with a special rubber disc attached to the drill, it rubs off the glue like a pencil eraser.

And with fats, be careful not to saturate the wall, because then you will never paint it with anything else.

It does not dissolve these adhesives well.

They evaporate too quickly, but they will destroy / dull the paint coating or the frame material.

And what is it, because I have not heard about such a chemical compound yet

"orange acid" because it smells like an orange, it is LabelOff's aromatic hydrocarbon compounds that make it in its composition

I know about it, but I would never call it "acid" (unless my friend used some translator )
This is exactly what it is limonene which has absolutely nothing to do with any acid.

I know this pain, I fought with Velcro from mosquito nets but in my case it went from the preparation to stickers for car windows + mechanical persuasion. Hot steam works well with old stickers, but hardly anyone has access to such equipment.

Once upon a time I had contact with an ideal agent for such old tapes and it was a medical agent, unfortunately the composition was not given. The agent evaporated instantly (a few or a dozen seconds) but it was sensational. It was some kind of spray spray for chronic wounds or something like that.

I probably also had contact with this and I even have some orange-scented cotton pads somewhere to wash off the remnants of the adhesive from the dressings, but with this spray agent what I wrote above is pale.

Try pb95. If it does not help, then probably only mechanical removal.

This sponge is probably polyurethane, so the material is quite chemically resistant.
You have to try to tear something off and then remove the glue.
Try isoporopanol (that is, isopropyl alcohol).
Safe in contact with the skin, does not stain, does not leave marks, evaporates quickly, does not destroy plastics, but generally dissolves adhesives. For this cheap. In chemical wholesalers. costs about 10-15 PLN / l.

I had a similar problem with the window frames but it was related to adhesive tape ...
The tape stuck on the outside under the influence of the sun even "vulcanized" with the plastic frame.
This preparation helped me:


In general, he cleaned everything up - even the old emulsion from the last century ...
I'm not saying that you will splash and everything will run off ..... you also have to scrub, but the torn piece of glue does not smear and does not stick again.
Shake the container (two-phase agent), spray it, wait a few minutes, then spray it again and scrub the soaked ones.

I clean such things with vegetable oil. I lubricate and then a paper towel or rubbing finger. The whole thing is that the glue is 3ma. when you lubricate with oil and rub, you break the structure of the pollution and oil enters. The glue has nothing to do with 3mac. You can wipe it off gradually anyway. Cheap but time-consuming method.

Because of the "porous" structure, you must first mechanically remove as much as possible.
Then with a preparation for removing stickers.
Fresh orange peel can be used as a substitute. Breaking it, sprinkle the juice that peels the glue. It should dissolve.

Good morning.
I use the N-Butyl Acetate reagent to remove extremely resistant stickers from jars, bottles and once also a secondary tape as described here. = 416 or Cyclohexanone - short description (It is also used as a solvent for insecticides, wood paints, paint and varnish removers, stain removers, as well as natural and synthetic resins and varnishes; as an additive to detergents, metal degreasers, and, among others, as aviation fuel additive. Cyclohexanone is well absorbed through the skin, respiratory tract and gastrointestinal tract. The main metabolic pathway leads to cyclohexanol, which, after conjugation with glucuronic acid, is excreted in the urine. .) Acute exposure is characterized by irritation to the eyes, nose and throat. Two people experienced somnolence and kidney disease, but they were also exposed to other compounds. Liver dysfunction was found in the group of people employed for over 5 years. here is the safety data sheet - https://www.carlroth.com/downloads/sdb/pl/C/SDB_CP27_PL_PL.pdf
As you can see, these are not very user-friendly reagents and when using them, you need to be very careful to protect your eyes and skin so that there is as little contact as possible and, of course, rubber gloves. But they have the advantage of simply removing the glue. It is best to break mechanically as much as possible the adhesive tape, make a tampon of cloth and cotton wool and soak it with solvent and rub. If anyone is allergic to odors this mask is either NOT USED.

As I mentioned, they are different adhesives and what I wrote about it works for most of them.
The window is made of PVC and acetone doesn't touch it - and nitro leaves a tarnish

Orange acid - ask Uncle Google, or read the chemical composition of solvents for stickers, adhesives, or on some hand washing pastes, especially used by motorists, lubricants, paints are perfectly clean, in medicine and cosmetics is also very popular.

I think it was ATER (diethyl)

Added after 4 [minutes]:

"Compulsively smelling or consuming ether is called etheromania." - Wiki
but it was ... you could be wrong

Perhaps it so happens that I found an empty package that I left behind when I need a super remedy for annoying glue marks.
It was exactly like that. Link

If someone decodes the chemical composition of this preparation, please let me know because the product is a revelation.

I would like a reliable link, please.
Buddy, this is a technical forum and I don't use any pseudo-technical nomenclature here.

In my case, the preparation recommended by my friend proved to be successful SIEKIERA_666 . I bought it to clean the roller shutters and cleaned the window frames made of PVC. I also removed the remnants of the tape from the internal blinds, but I had to work hard on it. I recommend the preparation.

I, however, have such a preparation for stickers (the smell resembles a liquid for cleaning the heads of printers).

I can do it, but the medical one was much better.

Normally up muzg promotes as I read about washing off IPA adhesives or alcohol.

"Żre" everything, including polycarbonates. I think even the nitro solvent should get the glue off the ground - just give it a little work before it evaporates. With acetone (the same as nail polish remover) I wouldn't even come close - it dissolves PP and PE.
