### ⭐⭐⭐⭐⭐ Very good quality

excellent contact cleaner - does just what it says it does

### ⭐⭐⭐⭐⭐ Making Contact
*by A***U on 17 July 2026*

Came to use my battery operated garden equipment after lying idle over the winter period and they wouldn't start or if they did the results were patchy. The equipment was stored in a dry environment but would have been subjected to rises and falls of temperature. didn't expect the electrical internals to the kit to have issues so didn't use the spray straight away. However, I eventually indiscriminately flooded the electrics with the spray using the very handy directional straw, left it for a couple of minutes then manually jigged the cutting blades / chain before reapplying power (DON'T forget to do this with the battery removed / unplugged) and they sparked into life. Can only think that a very small amount of moisture had created a corrosive barrier on contacts (not that I know !) but irregardless the product worked and thus a much more economical solution than alternative choices.
