MG Chemicals 408C Rubber Renue, Rejuvenate and Restore Rubber Belts, Platens and Rollers, 125ml Liquid Bottle

Used it a couple of hours ago on a 1948 Sterling Continental typewriter's rock hard, and pitted with "full stops", platen. At the time of application, it cleaned and left a stickier platen to the touch than my tried and trusted Platenclene spray. Very happy. Two hours later, the shine has gone as has a lot of the sticky feel but the platen looks and feels better for it. Still happy. I'll give each of my machines a little go with some as and when they come into rotation. Word of warning, the chemical smell is VERY strong. (Like TCP on acid). Use sparingly and in a ventilated room to avoid "issues".

Yes, it's very expensive. But I took a chance and bought it to refurbish the pinch rollers on my 50-year-old Sony TC-788-4 reel-to-reel tape deck. They were glazed, shiny and hard, and would not move the tape correctly. I did two rounds of applying the Renue according to the instructions, with a good cleaning with alcohol after each round of Renue. I got a LOT of black residue off, so I knew the Renue has opened up the rubber surface. Afterwards I did a very light scuffing with fine grit sandpaper. The capstans are now a nice matt color, and they are working nicely. Be sure to use this stuff outdoors or with an exhaust fan; it's very volatile. I wore nitrile gloves. I should have used an eye covering because my eyes watered for a day after using it. After closing the jar, I put it in a thick sealed plastic bag to help contain the fumes. Just be careful, but the stuff really works.

A redonné de la qualité ey de l'élasticité au pinch roller de mon revox. Super.

I was introduced to this product when I bought my second car by a body shop employee. It does what is is supposed to do. Just know this stuff is caustic in one form or another and it "does what it is supposed to do", so be responsible with its use and disposal. Great Product, saved the restoration of an old fishing vessel, brought the rubber flange back to life, very happy since the ports were not replaceable.
