Well guys the man does have a point. I had some vinegar mixed with water that i used for a few things here. I pour some out and put some triflow minus the garlic and again the man has a point. The only thing is the inclined chemist will have to analyse if the chemistry would do any harm to the rubber.
but seriously this works great, it cleans those white pinch rollers like butter.

An update to the above. I was trying out this thing on some used parts and it seems to work great. Only thing is it seemed like the mixture looked like oil mixed with water at first. I was a bit curious at how it made everything look clean and new. Then i thought if it was oil residue that was causing that effect. So i went to giggle and below is a explanation. Sitting at my bench, the mixture does have a smell of vinegar and if garlic is added then the aroma might be too much. But it does remove dirt.

An emulsion is a suspension of two liquids that normally do not stay mixed, like oil and vinegar. Normally, if one pours oil into vinegar, the oil will float on top of the vinegar. Oil is less dense than vinegar. However, the main reason why this happens is because oil is a non-polar substance, and vinegar is a polar one. Substances with dissimilar molecular structures do not interact easily.
In order to keep this separation of liquids from occurring, it is necessary to whisk the oil and vinegar together, forming a temporary emulsion. Still, the temporary emulsion will eventually separate into two layers of the original liquids. For a permanent emulsion, an emulsifying agent is necessary to molecularly hold these immiscible liquids together.

That's called a colloidal suspension. The two substances seem to mix, but never really do. Given a few minutes it will separate back out into layers.

Hello brother
not all believe in simplicity

Re: to alcohol or not to alcohol

50-50 soft soap and water to clean rollers, covers, cabinets. Depending on fragrance, smells nice too. Alcohol on original cover and for pen/white out marks. Besides alcohol can be expensive,

Re: to alcohol or not to alcohol

try this
small garlic with a drops of vinegar and drops olive oil

True ?

Garlic is sulphur based,Vinegar is water + acidic acid, and olive oil is a natural hydrocarbon base oil.
In simple terms ,you have a miscible water+acid mixed with a non-miscible oil ????
Once the water and acid have cleaned the area, you will be left with an oily residue. The oil will make everything look shinny new.
You might be better off using grandma's cleaner. ie. cup full of vinegar mixed with half a cup of bleach (Sodium-HypoChloride). If it's a mouldy area, add a couple of drops of clove oil.

Well you never know till you give it a go, it might work on natural rubber compounds... I might even try it one day....

Re: to alcohol or not to alcohol

I have two flip cap bottles of cleaner in my tool case.
1. 1 x bottle of Methylated spirits.
2. 1 x bottle of Spray-an-Wipe (Ammonia based) cleaner.

Use of the above cleaners depends on which machine I'm working on.
It all depends on the roller I wish to clean. I will often use water with a squirt of alcohol to speed up my work day.

I will sometime use water and alcohol on a coarse scour pad to clean really grubby rubber rollers.

In saying the above. I would like to know the MFD rubber compounds used for various climates and different countries. I live in a warm tropical climate. The rubber compound used in other climates might make a major difference to the cleaner I would use.

The MSDS sheet for menthylated spirits is quite alarming.

Re: to alcohol or not to alcohol

The MSDS sheet for menthylated spirits is quite alarming.

I actually use in most part "Ethanol" not "Methanol". Very near the same solvent properties though.
Methylated spirits is a mixture of both Ethanol and Methanol in various ratios, depending on the manufacturer.


Your right about the statistics for "Ethanol" use it is quite alarming, especially when mixed with Coke & ice cubes in a glass...

Well, Mr. matrix, was just looking out for you there when i saw the MSDS for the stuff, just had to push the red button. You know the saying, if it works for you, then by all means.

Re: to alcohol or not to alcohol

The reason i stay away from oil based cleaners for the rollers are, if they are not completely cleaned off the rollers, then the oil can be transfered to the drum, dev, transfer belt and it make a simple cleaning job into a troubleshooting print quality problem. Most of the guys seem to like wd40, so i guess it works well. Has anyone tried KRUD CUTTER ?.

Thanks for the post. I have seen this happen as well, usually the engineer gets carried away and spray and prays and the oil is transferred through the machine and is a bugger to clean out. WD40 on a rag only is my rule.

Re: to alcohol or not to alcohol

thanks everyone for all your input and suggestions and your time to respond. I think I have enough info to make a decision and majority rules . I am going to say no to alcohol and only keep a small supply for those one off times when its actually needed.

we need to remember and treasure those special moments at work when we really enjoy what we do...trade those old machines in and smash the crap out of them...

Re: to alcohol or not to alcohol

I would be afraid to transfer alcohol. Better to drink it with a hot piece of steak and a roast potato. I love that kind of food, but I'm getting fat

Re: to alcohol or not to alcohol

i have been using D-Ink on rollers for years. i have had times i use windex and it doesn't always clean well enough. usually if i break out the D-ink then i am back in business.
