Can Brake Cleaner Damage Plastic Electronics Covers? A Comprehensive Guide
Brake cleaner is a powerful solvent designed to quickly and effectively remove grease, oil, and other contaminants from brake components. However, its potent cleaning ability raises concerns about its potential to damage delicate plastic parts, especially those covering sensitive electronics. The short answer is: yes, brake cleaner can damage plastic parts, depending on the type of plastic and the cleaner's formulation.
This article delves into the specifics, providing you with the knowledge to safely use brake cleaner around sensitive electronics.
Understanding Brake Cleaner's Composition
Brake cleaners typically contain solvents like acetone, methyl ethyl ketone (MEK), or other petroleum-based chemicals. These solvents are highly effective at dissolving grease and grime, but they can also dissolve or degrade certain types of plastics. The specific composition varies between brands, so always check the product label for details.
Types of Plastics Affected
Not all plastics are created equal. Some plastics are highly resistant to solvents, while others are easily damaged. Common plastics found in automotive electronics covers include:
- ABS (Acrylonitrile Butadiene Styrene): Generally resistant to many brake cleaners but prolonged or concentrated exposure can cause damage.
- PP (Polypropylene): Often more resistant than ABS, but still susceptible to damage depending on the cleaner and exposure time.
- PC (Polycarbonate): More resistant to solvents than ABS and PP, but still not completely immune.
- PVC (Polyvinyl Chloride): Can be easily damaged by brake cleaner.
Identifying the exact type of plastic on your electronics cover might be difficult without detailed documentation from the vehicle manufacturer. However, you can usually find a recycling code (a triangle with a number inside) molded into the plastic. This code can give you some indication of the plastic type.
Signs of Brake Cleaner Damage
If you've accidentally sprayed brake cleaner on a plastic part, watch for these signs of damage:
- Cracking or warping: The plastic may become brittle and crack or deform.
- Discoloration: The plastic might change color, often becoming hazy or dull.
- Surface degradation: The plastic's surface might become rough or pitted.
- Embrittlement: The plastic becomes less flexible and more prone to breakage.
Safe Practices When Using Brake Cleaner Near Electronics
To minimize the risk of damage:
- Test in an inconspicuous area: Before cleaning anything near electronics, test the brake cleaner on a hidden part of the same plastic type to see how it reacts.
- Use sparingly: Apply the cleaner sparingly and avoid excessive spraying or prolonged contact.
- Keep it away: Whenever possible, avoid spraying brake cleaner near sensitive electronics. If you must clean nearby, use a targeted application and shield electronics with plastic sheeting or masking tape.
- Proper ventilation: Use brake cleaner in a well-ventilated area to avoid inhaling the fumes.
- Choose a less aggressive cleaner: If possible, opt for a less aggressive cleaner, such as a citrus-based degreaser, for cleaning near electronics.
Alternatives to Brake Cleaner
For cleaning near sensitive electronics, consider gentler alternatives such as:
- Isopropyl alcohol (IPA): Effective for removing light grease and grime.
- Citrus-based degreaser: Environmentally friendly and generally safer for plastics.
- Compressed air: Useful for removing loose debris.
Remember, prevention is key. If you're uncertain whether brake cleaner is safe to use near specific plastic components, it's always best to err on the side of caution and use a less aggressive cleaning method. Damage to plastic electronics covers can be costly to repair, so careful handling is crucial.
