Yes, i use the NPS 1260 on all cable connections. Have applied it to the male end of my XLR cables. With good results, just be careful you only get it on the pins with no spider webbing between pins. Have used it on speaker cables both ends, speaker jumpers both ends, some on speaker binding post, power cord prongs and the MC 05-to the Pro wave guides.
I did see Rick and crew apply it to the female ends of XLRs and to the female end of power cords (unplugged of course).
I believe the sell ends on the 16 of July. But would check their web sight for sure or call them.
The HF cleaning clay was used to clean any debris of the cables that the magnets pulled in. (small metal filing).
Good luck
