To alcohol or not to alcohol?

Re: To alcohol or not to alcohol?

While I wouldn't want to drink Sel-Sol, it is pretty benign. The MSDS sheet lists mild skin irritation if used excessively, but no special measures are needed while using. And it does a great job at cleaning and preserving both rubber and neoprene rollers.

It's not what is listed on the MSDS sheet i am concerned with, but what i have seen this product do. As you said it does a great job with not only rubber, but removing toner, glue and will not harm plastic. I have seen this product soften epoxy. It has no irritations to the skin and no odor. But why i have stopped using it, is the penetrant factor and how quickly it does it. You can't help it at times, as the product will get into your skin and pores and eventually who knows where it ends up. Just my concern. Plus if it is not used correctly, say left on too long and with too much applied it will get between the roller and hub and the roller will spin and especially the transport rollers, you can get call backs and be stumped. If used correctly and with caution[chemical gloves], it is great. I personally keep a little for removing labels from drums ect, but not as a everyday cleaner.

i use alcohol and see no problems, i used varn V-120 blanket wash for 15+ years no problem either.
there is a chemical in it that even rejuvenates the rubber

You know, I've been using WD40 on feed rollers for quite a while, but I never thought of using it on corona wires. I'll have to try that out.
Thanks!
If you have a steady hand and a gentle touch, you can substitute an eraser for the green pad/soapy water initial combo. At least that's the way I do it. They're kind of hard to come by any more, but I've found that pen or typing erasers work best.

Well, I never used WD-40 on Corona wires, but I did use the pen/ pencil erasers as well, in combo with alcohol, especially back when they could smoke inside buildings. It seems as though tar and nicotine were magnetically drawn to corona wires. I swear I serviced an old Sharp SF-760 in an Eagles Lodge and I was either changing or cleaning Coronas every week because the tar and nicotine would cause them to short out. When Sharp came out with the saw-tooth coronas, I would use Styrofoam to clean them, back on the AR-337, 407, 507 series, wait... they started using that main saw-tooth corona on the SF-2022, 2027, 2035 series.

Re: To alcohol or not to alcohol?

it's okay every now and then but long term it dries up the rubber and becomes hard and slick.
