Cleaning VCR heads
I have just finished reading the sticky thread, and I noticed someone mentioned they cleaned their play heads using their finger nail.
I was wondering how safe is this, I know the recommended is to use chamois swabs or paper and IPA, but I don't have any of these and probably won't be able to get any for a while. I don't want to break the heads off, so I just want to check it's okay as this is my first VCR I've ever had - and only - so I don't want to break anything. Thanks |

Re: Cleaning VCR heads
Hi, VCR heads are fragile and easy to damage. If in doubt use a tape cleaner or a soft lint free cloth, with IPA or meths, with little pressure while rotating the head by hand slowly. Let the head dry for few mins before playing a tape, as moisture on the head will cause the tape to stick to the head and damage the tape as well as the heads. This is why if the VCR is moved from a hot to a cold location you should allow time for condensation to evaporate. Any one remember i think Sanyo Betamax with the auto sense condensation circuit that stopped it working if triggered. Try explaining that to a customer that you had just delivered it back to after a workshop repair. Hope this helps.

Re: Cleaning VCR heads
Hi, thank you for your help. Would some tissue paper be okay to use, or would it be too abrasive?
I cannot get hold of any IPA so I'm in a bit of a jam. Thanks |

Re: Cleaning VCR heads
A business card GENTLY applied with head rotating and no IPA if desperate,you can get a load cheaply from Ebay of nail polish removal cloths.Perfect with IPA.
Clean from r/handside with the head going anti clockwise.

Re: Cleaning VCR heads
Years ago in the bush in Nigeria we used the local gin if we ran out of IPA. This was on 21 track seismic data recorders and didn't do them any harm. So, if you are desperate try gin or vodka, you can always drink it afterwards!

Re: Cleaning VCR heads
Back in the day I've used whatever was to hand in desperation. Clear spirits like vodka and gin did the job ok. Whatever you do though never use an up and down motion as you will break the head chips. And don't use cotton buds.

Re: Cleaning VCR heads
Indeed; tissue paper is also a bad idea as it creates dust and will shed quite easily. A good demonstration here on how to clean video heads (skip to around the 7:30 mark).

As others have said, i kept the paper/card still and rotated the drum many times until it was clean. It’s lucky I read up first, as my instinct is to clean with cotton buds. John - That’s good to know, thanks for the video too, I found it very helpful Thanks |

Re: Cleaning VCR heads
Surgical spirit from Boots is also an effective and gentle solvent

Re: Cleaning VCR heads
The last time I ordered a bottle of IPA from CPC they sent an aerosol can. Is this normal practice?
I have also used surgical spirits which does the job. |

Re: Cleaning VCR heads
The biggest issue is ensuring that there is zero vertical movement of the cleaning device/finger as it is applied to the heads. This can normally be achieved by resting/locking your cleaning finger against the immovable base of the head stack. Any vertical movement is likely snap off the very thin video head chips. Conversely I once read that the biggest mistake that most people make when cleaning video heads is insufficient pressure. So it's kinda careful, kid gloves in one respect and a bit of umph in another. I never snapped a head off anyway.

Re: Cleaning VCR heads
Do not use cotton buds! IPA is available on Ebay.

The closest household solvent to IPA is spirit (denatured alcohol). It has a blue colouring agent in it, but in practice that doesn't really seem to be a problem. |

Re: Cleaning VCR heads
I worked in a TV repair shop for many years and all we ever used was Methylated Spirits on a piece of good quality paper. As others have said keep your finger stationary and rotate the head drum.

Re: Cleaning VCR heads
In the African bush we used any clear spirit, usually vodka, and the edge of a newish banknote.

Re: Cleaning VCR heads

Re: Cleaning VCR heads
A plastic bank note is just that, plastic..... as such, non absorbent, and will not take any of the solvent up.
A clean bit of pure cotton sheet would suffice, but nothing fluffy - it's not like you are looking to shift ground in dirt, you are just looking to remove a build up of oxide from the head. You could toddle off to pound land, or somewhere like that and get a cheap Chamois - there's loads of places around London that are only a tube ride away.
