bluehorizon Clean It - cleaning liquid for contacts

A hi-fi chain is only ever as good as its weakest link - and this link is often invisible. Oxidation, dust, manufacturing residues such as silicone oil and simple corrosion are deposited at every connection point: on RCA cinch sockets, speaker terminals, jack connectors and mains contacts. The result is increased contact resistance, which makes the signal noisy, compresses the dynamics and dulls the spatiality - often so insidiously that you only notice it once it has been removed. This is exactly where Blue Horizon Clean-IT comes in: a professional contact cleaning fluid that has been specially developed for use in audio components.

Clean-IT was developed by Blue Horizon - a British company based in Winchester, which was founded in 2008 by Keith Martin, the founder and managing director of the renowned power conditioner brand IsoTek. Clean-IT is backed by over a century of cumulative experience in the audiophile accessories industry. The formula works on four levels simultaneously: it cleans, conditions, lubricates and preserves - and thus permanently protects contacts from renewed oxidation. The result is not sound coloration, but a signal path that can finally work unhindered.

Electrical connections are inherently imperfect. Even brand new plugs and sockets are treated with silicone oil during the production process, which remains as an insulating residue on the contact surfaces after drying and impairs conductivity from the outset. In addition, dissimilar metals - such as gold-plated plugs in nickel-plated sockets - trigger electrochemical reactions that further increase the contact resistance. Clean-IT addresses precisely this problem: the formula specially developed for audio applications quickly dissolves oxidation products, grease and dirt particles and at the same time stabilizes different metal pairings to ensure optimum contact over the long term.

The four-fold effect of Clean-IT makes it fundamentally different from simple spray cleaners: it cleans contamination, conditions the metal surface, lubricates the connection point for more secure mechanical contact and preserves the contact surface against renewed oxidation. This lasting protective effect means that the treatment does not need to be repeated after each season - the effect is long-lasting.

The British trade magazine Hi-Fi Choice independently tested Clean-IT and came to a clear conclusion: the contact resistance on treated connections was reduced by up to 50 %. What sounds like dry electrical engineering has direct sonic consequences in practice - the noise is reduced, the dynamics open up and instruments appear spatially more precisely located. Anyone who has never treated their system with specialized contact care will experience the difference not as a subtle nuance, but as a noticeable leap in quality.

Particularly revealing: Clean-IT doesn't just work on old, neglected equipment. Brand new components also benefit directly - because the silicone oil residues from production mentioned above are present from the outset and are only completely removed by targeted treatment. This makes Clean-IT a sensible initial treatment for every new device that is integrated into the system.

Application is extremely straightforward: Using the enclosed applicator brush, Clean-IT is applied thinly to all metal contact surfaces - RCA cinch plugs and sockets, speaker terminals, jacks, banana plugs, mains plugs and all other connections between devices and cables. Then connect the plugs as usual and wipe off any excess liquid with the cleaning cloth provided. No waiting to dry, no rinsing, no effort. One bottle of Clean-IT is enough for several complete system treatments.

Clean-IT is safe on all metallic connection materials used in audio technology: Gold, silver, rhodium, copper and nickel - making it compatible with virtually any audiophile cabling and equipment terminal, regardless of manufacturer or price range.
