@willgolf There should be some left on the other end of the connection. Doesn’t hurt to reapply though if connections have been remade a few times.
1260 does seem to help USB and HDMI connections.
The case is useful for neat storage, but AI’d save the money if you already have 1260.
i would think the 1260’s thin applicators would work for cleaning female ports, but what has HF said about whether or not cleaning is a necessity with the new stuff?
