Customer Questions & Answers
-
Question:
What is CRC Knock’er Loose Penetrating Solvent used for?
Answer: CRC Knock’er Loose Penetrating Solvent is primarily designed for loosening rusted or corroded components. It penetrates difficult to reach areas, making it ideal for bolts, nuts, and other metal parts that may have seized over time due to rust. The solvent effectively breaks down rust and grease, making mechanical work easier and reducing the chances of breaking hardware during repairs. -
Question:
Can CRC Knock’er Loose be used on electronic components?
Answer: While CRC Knock’er Loose is a versatile product, it is best to avoid using it directly on sensitive electronic components. The solvent may affect insulation materials or components that are not designed to handle oils or liquids. Instead, for electronic repairs, consider using dedicated electronic cleaners that do not leave residues or interfere with electronic circuitry. -
Question:
Is CRC Knock’er Loose safe for use on painted surfaces?
Answer: CRC Knock’er Loose can potentially harm painted surfaces, as it may strip away paint or finish. When using this product, it is best to test it on a small, inconspicuous area first. For tasks involving painted surfaces, utilize alternatives designed specifically for sensitive materials to avoid damaging your finish or requiring additional touch-ups. -
Question:
How long does it take for CRC Knock’er Loose to work?
Answer: The effectiveness of CRC Knock’er Loose can vary depending on the extent of rust or corrosion. Typically, it takes a few minutes after application for the solvent to penetrate and start loosening the rust. For best results, apply the product, let it sit for 5 to 15 minutes, and then attempt to loosen the fastener or part. In tougher cases, reapplication may be necessary. -
Question:
Is CRC Knock’er Loose suitable for automotive applications?
Answer: Yes, CRC Knock’er Loose is ideal for automotive use. It works well on seized bolts, rusted engine parts, and other automotive components. Mechanics and DIY enthusiasts alike can use this product to facilitate easier repairs and maintenance, ensuring that mechanics do not struggle with stuck parts during tire changes, engine repairs, or regular vehicle maintenance. -
Question:
Can I use CRC Knock’er Loose in confined spaces?
Answer: When using CRC Knock’er Loose in confined spaces, proper ventilation is crucial. Although the solvent effectively penetrates tight areas, inhaling the fumes can be harmful without adequate airflow. Always work in well-ventilated areas or wear appropriate respiratory protection if required, especially in enclosed environments. This ensures safety while accessing hard-to-reach components. -
Question:
Does CRC Knock’er Loose leave any residue after use?
Answer: CRC Knock’er Loose typically dries clean without leaving a sticky residue. However, it is advisable to wipe off any excess with a clean cloth after application. This helps maintain a clean surface and prevents any potential buildup of particles that could interfere with the operation of mechanical parts over time. -
Question:
Is CRC Knock’er Loose flammable?
Answer: Yes, CRC Knock’er Loose is classified as flammable. It contains solvents that can ignite if exposed to open flames or sparks. Always store it away from heat sources and use it in well-ventilated areas to minimize fire risks. Following these safety guidelines ensures that you can use the product effectively while maintaining safe working conditions. -
Question:
How do I apply CRC Knock’er Loose for best results?
Answer: To apply CRC Knock’er Loose, first, clean the area around the rusted component. Shake the canister well, then spray an adequate amount directly onto the affected area. Allow it to penetrate for several minutes, then attempt to loosen the fastener. For stubborn cases, repeating the application may be necessary. Using a combination of socket wrenches and a firm grip will often yield the best results. -
