Hey guys I was just in the midst of cleanin my deck and ran into a jam. My rubber pinch roller has a decent amount of tape residue on it and the usual soap and water remedy has failed me. Do any of you guys have a "chemical X!" to help with the residue?

I'm worried my demag isn't functioning, if I try it out would I be at risk to further magnetize my heads?

Sorry newb question but do you normally demag the eraser head?

Thanks guys,

If it's not working right...then don't use it. Last thing you want is to magnetize the heads more, and then not be able to demag them.

I might get some opposition to this...but frankly, I think the need for demagnetizing can sometimes be overstated. To just demag on some set time schedule may not be the best approach, as some people seem to do.

Use a magnetometer to check the Gauss levels at the heads and transport (you get one with the R.B. Annis kit). If you are seeing anything under 1 Gauss needle deflection from your "normal" position as you bring the meter/probe next to the heads...then don't degauss.
I usually see less than 1/2, and running the demag does NOTHING, as that is probably just the overall magnetism of those metal parts due to the earth’s magnetism in my area.

Straight from the engineers at R.B. Annis :
1 Gauss and over, it's time…over 2 Gauss, your heads/transport are now retaining heavier magnetism.

But if you have less than 1 (or less than 1/2, like I do)…demag one time and check it again…if you see NO change, then that is constant magnetism from the earth on your metal parts…and you will never be able to remove it, so don’t just keep demagnetizing…’cuz you can do more damage than good!!!
You first need to know what “normal” amount of magnetism is coming from the earth that is affecting your metal parts, and then see how much deflection from the “normal” position before you demag.

I figured this was the obvious answer, but I wanted to test it out to check if it worked but was wondering if it was possible to magnestize them even more with a bad demag before checking.

Thanks for the help,

What is the link to "R.B Annis"? I am interested in getting the Magnometer.
