Okki Nokki Record Cleaning Machine

Introduction
I have always taken what I consider as good care of my records. I only touch the outer rim and label, I always clean with a brush before playing (and sometimes after). However, I still have some records that I suspect would benefit from a really good clean - especially some of my oldest ones and also many bought from new recently which appear to suffer with mould-release residue.

So what are the options? You can go for a manual approach, which involves lots of different brushes and lots of time and patience - or you can look at a Record Cleaning Machine. I have always fancied the latter but the price of such machines is rather off-putting. The thing that most made up my mind was that my brother-in-law gave me a large batch of records that had been lying around his loft for the past 10 years. These were in a terrible condition as many had been left out of their sleeves (he was never any good at looking after records himself) but they held a great nostalgic value to me as I grew up listening to many of them and some you simply can't get anymore (even on CD). The option of an RCM (Record Cleaning Machine) also opens the door to buying quantities of cheap used records from charity shops, car boot sales, etc.

I pondered a great deal over which RCM I should go for. Fortunately, a friend who I correspond with recommended the Okki Nokki RCM. This appears to be pretty much equivalent to the VPI 16.5 (minus its lid but plus forward and backward rotation) but at a considerable lower cost. I did a little more investigating and found this to be highly recommended by its users so off I went...

The price of the Okki Nokki is pretty much fixed at a standard price in this country (UK) at 295 (at time of writing). However, I found that a Hi-Fi dealer called The Emporium also throw in some freebies such as spare felt pads for the vacuum arm, free anti-static record sleeves, and a spare vacuum arm for 45's (I never play 45's so they sent me a spare bottle of the Okki Nokki cleaning concentrate instead). I found Nick at the Emporium to be most helpful and cooperative. I ordered the RCM on the Friday and told to expect its arrival on the Monday and that's exactly what happened.

The Okki Nokki is manufactured in Germany and is supplied throughout Europe (I don't know if it is available elsewhere or not). It's manual is supplied in three languages (English, German, and Dutch?).

Above left, you can see the RCM as it comes out of the box. Above right are the standard parts and accessories that come with it. The unit comes with:

Each bottle of concentrate is to be added to 1 litre of purified water.

Basics
Assembling
Assembly couldn't be easier. Apart from inserting the power cord the suction arm needs positioning into its opening.

A velvet pad is stuck to each side of the slot in the suction arm. These should be checked regularly for wear and dirt build-up. I was supplied with some spares by my dealer free-of-charge.

A cylinder protrudes from each side of the suction arm that correspond with slots in its housing. These are used when the arm is swung around to its active position and allow it to be lowered onto the record at the correct angle.

Preparation
Before cleaning, you will have to mix some cleaning solution. The cleaning solution that is provided comes as a concentrate and has to be diluted. This should be done in the cleanest water available.

I got some distilled water from the local chemist. Distilled water is very cheap - cost me about 20 pence per 500ml. The bottles were extra (£1.65 each) but can be taken back to be re-filled.

Each bottle of 50ml concentrate creates 1 litre of solution. The picture shows 2x 500ml bottles.

I don't know much about the Okki Nokki solution itself - other than it is alcohol free and can therefore be used on 78-rpm shellac records.

There is a lot written about cleaning solutions and an amount of research and experimenting is recommended. The manual recommends that if alcohol solutions are used, they should not exceed 25% alcohol.

Operation
The front panel sports two switches. The first is the rotation switch - this has 3 positions, allowing clockwise or counter-clockwise rotation.

The second switch switches the vacuum on and off. Nothing much to report here - they are switches and they work as they should - just make sure you don't switch from one direction to the other without stopping for a second first to avoid putting too much stress on the motor.

I was impressed by the amount of power that the motor appears to have. It allows you to use quite a lot of pressure onto those hard to clean records without complaining.

Emptying
You are, of course, sucking up liquid that ends up inside the RCM so this will need emptying every now and again. The manual recommends doing so every 30 to 40 sides. It says that the machine does automatically shut off when an internal capacity of 350ml has been reached but I would suggest getting into the habit of emptying regularly so that you don't end up thinking you have a faulty machine only to discover that it is simply full.



On the rear of the unit you can see a 'fluid release tube'. This has to be gently pulled out and the red stopper removed before tilting the machine backwards so that the fluid can be drained into a suitable container. Once emptied, replace the red stopper and re-insert the tube.

I was quite surprised the first time I emptied the RCM. I wasn't expecting so much dirt to be evident. This goes to prove its effectiveness at basic cleaning!

In Action
I tend to clean each side of a record twice - first in the reverse direction when I 'scrub' the record and lastly in forward direction; although this could be looked at as simply a rinse. I like the idea of beginning the clean in reverse direction, as it is opposite to the way it will normally have been cleaned and therefore theoretically easier to clean any dirt that has been laid down and pushed into the groove by either the stylus or brushes etc. I'm sure that other users will have their own regime of cleaning but finding the best way for you is part of the fun.

You will not remove all moisture from the record's surface with the vacuum - this is because the felt pads on the vacuum arm will inevitably get damp and leave a slight smear of liquid on the surface; especially around the place the arm is lifted from the record. The amount will increase with the number of cleaning cycles done before allowing the pads to dry. It is therefore important that once cleaned, a record is allowed to stand in air so it can dry thoroughly before playing - a plate rack is good for this, allowing you to stand the record upright.


Cleaning with the Okki Nokki

Applying Gruv Glide

On some records - especially ones that are prone to static charges (some are more prone than others for some reason and can remain so even after cleaning), I also coat with some Gruv Glide. I have only started using this since I got the Okki Nokki because it's great for such things. I am quite impressed by the results - only a very light coating is necessary to neutralise static in most cases and I have not noticed any sonic degradation or residue build-up on the stylus. It also acts as a lubricant, possibly extending the life of the vinyl slightly? Many years ago, I used a Zerostat gun for removing static - today I haven't got the patience for this (I used it as you are supposed to - with long drawn-out squeezes rather than using it like a pepper mill as I have seen many others use it) and think they are vastly over-priced nowadays. Besides, the Gruv Glide works for a much greater period, of course.

Conclusion
The Okki Nokki appears to be well built and more than up to the job at hand. The motor power seems more than adequate and allows you to put a good deal of pressure onto the record when necessary without causing any obvious strain. When you consider its price, it is a real bargain. I have been using the unit for a few months now and haven't had any problems with it - it does what it's supposed to do.

I'm still not 100% happy with the cleaning however, but I think this is more to do with the cleaning solution, and perhaps brushes, that I am using rather than the machine. I have seen from emptying the Okki Nokki that it is removing plenty of dirt. However, because I have so much of the supplied cleaning solution left, I have not been experimenting with other formulations although I do have a list of ones that I want to eventually try that I have read about on the Internet - that will be another story!

I can recommend the Okki Nokki as a machine to have a serious look at if you are thinking about an RCM - it does what it's supposed to do, it's cheap, and it's well built.
