Before using this product, all food products and packaging must be removed from the work area and placed under protection. It therefore falls into the category of cleaners for electrical equipment: “ use permitted as a solvent for cleaning of instruments and electronic devices which do not tolerate aqueous cleaning solutions in and around food processing areas, provided that the cleaning product is not intended to come into direct contact with food. Its Kb value is 62.3 KbV, so it is considered neither as a mild solvent, nor as an aggressive solvent and is therefore a good compromise for cleaning electrical components efficiently, without risk of damaging them.
Unlike some contact cleaners on the market, WD-40 Specialist Electrical Contact Cleaner leaves no residue or deposits that could build up and possibly cause problems, such as a short circuit. In addition, it prolongs the life of electrical equipment and is compatible with all plastics, rubbers and metals. It provides excellent cleaning performance, with minimal fuss, and removes dirt, dust, condensation, and flux residue with ease and without damaging sensitive electrical/electronic components. Our WD-40 Specialist Contact Cleaner is fast-acting, non-conductive and non-corrosive that is suitable to use on all sensitive electrical components. What is WD-40 Specialist Electrical Contact Cleaner and how do I use it? They are therefore potentially dangerous for electrical circuits. These solvents are so aggressive that they can accidentally damage certain materials such as plastics, soft metals, and rubber. Kb> 100’s = powerful (or very aggressive) solventĪ cleaning solvent with a high Kb value (> 100) is too aggressive for sensitive materials. A higher Kb value means that the solvent is more aggressive in its ability to dissolve certain materials. The Kauri-Butanol value is an international standard that measures the cleaning power of hydrocarbon solvents. Therefore, a contact cleaner must be less ‘aggressive’ (low degreasing power) to avoid damaging sensitive electronic components. Unfortunately, you cannot have both strong cleaning power and rapid drying. There is a balance between degreasing power and drying time. In these cases, the dielectric strength ensures that ‘breakdown’ cannot occur. The reason why dielectric strength remains an important factor in the case of WD-40 Specialist Contact Cleaner, is when equipment or devices are energised before the contact cleaner has completely evaporated. WD-40® Specialist Contact Cleaner has a dielectric strength of 33,800 volts. The material can’t withstand (nor insulate) an electronic current if the breakdown voltage is surpassed. What is Dielectric strength?ĭielectric resistance measures the ability of a material or a liquid to withstand an electric current before reaching its breakdown voltage. And when we speak of ‘contact’ it means an ‘electrical connection’ or the socket itself. An electrical outlet constitutes a ‘contact’. We talk about contact when two parts made of metals (or materials) conductors of electricity are connected to pass the current. So, what is an electrical contact cleaner? Well, let’s break it down… What is a contact? Whether it is oil, grease, corrosion, or a food substance that contaminates an electrical or electronic component, a contact cleaner can be used to effectively dislodge all of these foreign elements so that the components can be put back into place, in their original condition. Therefore, the purpose of using an electrical contact cleaner is to perform cleaning of electrical components so that they can function properly for an extended period. Within contact cleaner, you can use a number of cleaning chemicals however, isopropyl alcohol is the most common. Just what is electrical contact cleaner? What do we use it for, and how can we use it safely?Ī contact cleaner is typically an aerosol filled with compressed air and a cleaning agent. The term ‘contact cleaner’ is not necessarily obvious to everyone.
