For our Sony digital HD reel-to-reel machines, we used Everclear grain alcohol for head cleaning.

And here, lint-free Tech Wipes. Spin the head, hold the wipe steady. No up-and-down. No q-tips/swabs except for guides or stationary audio/control track heads.

Are your Sony machines HDD-1000 type?

Yes, they were HDD-1000.


[Off topic]: Charlie Rhodes (who was formerly head engineer of video test equipment at Tektronix, and during testing ran the Advanced Television Test Center (ATTC)), devised a frame format converter that would take any of the proposed scanning formats, slice it into rectangles, and piece it into the Japanese 1125 interlaced frame so the HDD-1000 could record and play it. Tektronix built a small quantity and sold them to proponents.
