Can I use this to clean my tape recorder heads?

Kontakt-Chemie Kontakt IPA Isopropanol-Alkohol, 200 ml - Elektronikreiniger/Entfetter - Reinigungs- und Wartungsprodukte - PK Elektronik Onlineshop: Weller Entlötstationen, Lötstationen, EGB/ESD, Ultraschallreiniger, Präzisionswaagen, Laborwaagen, Zä

On the can says:

"a high purity isopropanol for removal of dirts, oils, resins.. of PCB's, magnetic heads, fine mechanisms, etc. For magnetic heads, use a swab drenched in Kontakt IPA, otherwise spray directly onto parts"

The link is in German.

For cleaning tape heads you need just isopropyl alcohol and cotton buds.

Sorry about that.

The link says:

"The high-purity CRC Contact Chemie contact IPA isopropanol alcohol dissolves greasy dirt and water resistant ink. It is particularly suitable for the purification of video and tape heads, rubber rollers or small gearboxes, optical lenses, mirrors and high-gloss metal surfaces and the cleaning of drive components. "

The store that sells the regular isopropyl alcohol is out of stock.

Is this the same? (isopropanol = isopropyl?)

I'll use the cotton buds.

Isopropanol = isopropyl alcohol. I personally suggest 90% or higher.

.if you get it from the local pharmacy or supermarket there is too much water in it as it's 70% or less

we used 99.5%

guessing above 90% would be okay

This spray is used to clean electrical components, and it mentions tape recorder heads.

It's basically isopropyl with carbon dioxide but I can't find the percentage of alcohol.

What happens if it's less than 90%?

Go to the hardware store and get some Denatured Alcohol.

Use the highest purity you can...as Sigma pointed out it can be found at 99.5%...Also, I would like to change my previous reply. Don't use < 95%.

Why use such a high purity?....because the balance is usually water. NOT TOO GOOD FOR ELECTRONICS!!! It is impossible to have 100% isopropanol due to hydrogen bonding.

And whatever you do, make sure you don't use "Rubbing Alcohol"...

Kontakt IPA is 99,7 % pure alcohol, 0,2 % water. The rest is unclear. Due to the Brochure of Welcome to CRC Industries Europe
More pure than this you can't find.
Still curious what's the other 0,1 % ...

It is likely this 0,1 % is oil residue left from the chemical production. In the long run possibly not so good for your heads or tapes.

To be on the safe side perhaps better to use distilled pure alcohol which goes to a max purity of 96 %. The rest is most likely water, which evaporates.
if I'm wrong, please correct me.
