Purchased to address the electrical 'crackle' heard through the speakers when rotating the volume and balance controls of an old unused amplifier. Accessing the internals and squirting cautiously into the control barrels, rotating the controls back & forth to distribute the fluid across the contacts (and then allowing to dry before testing) has transformed the amplifier back to being crackle-free. The only downside is that of purchase quantity vs amount required for this task - 2x 200ml purchased and i probably only used 2-5ml.

As an experienced user of this type of product find it very good value against much more expensive ones

Sceptical but quickly convinced , as long as you squirt in the right direction the offending part starts behaving as it should, in this example it was a noisy volume control, dried with an hair drier before switching back on !

I play and collect vintage electric guitars, any electrical noise from potentiometers or switches is a big No No, so I use spray contact cleaner at the first sign of any problems, it works a treat and really extends the usefulness of sometimes very old electrical parts, a few of my guitars date back to the early sixties or seventies and are completely original. If you think about it, some of the parts have been used and abused for sixty-plus years and do occasionally show signs of wear, some require replacement, but mostly a small squirt of contact cleaner does the trick, without doing any damage, so spray contact cleaner is a must have item for me, along with the guitars of course.
