Spanjaard is very well known product in SA, and their extensive range has been used by anglers and boat owners for many years.
I have been testing the Lectro Kleen spray on my boat and jetski electronics over the last 6 months to see how really effective this product is. I especially focused on the Power Cables for the radio, fish finder and GPS units.
These connectors usually are the ones that get corroded even after just a few trips without properly cleaning them with fresh water and lubricant.
This product has proven incredibly effective and I would highly recommend it. I spray a healthy dose of the product on my fish finder plugs after every outing and there is absolutely no sign of corrosion.
