Is Brake Cleaner Safe for Plastic? Seeking Advice!

Technical Discussions
1

I’ve been doing some maintenance on my car, and I came across the topic of using brake cleaner on plastic parts. I’m really concerned about whether it’s safe to use that stuff on anything plastic, especially since I’ve heard mixed opinions.

Key Points of Concern:

  • Compatibility: Does anyone know if chlorinated brake cleaner is worse for plastics compared to non-chlorinated options?
  • Damage Risk: I’ve read about brake cleaner melting or degrading plastic components. Has anyone had a bad experience with this?
  • Alternatives: If brake cleaner isn’t safe, what are some alternative cleaning solutions that work well on plastic parts?

What I Need:

  • Your personal experiences and any tips you have.
  • Recommendations for specific products or methods that won’t harm plastic.

I want to ensure I’m cleaning without causing damage, so any advice would be greatly appreciated!

I’ve read that brake cleaner can be very harsh on certain plastics, particularly ABS and PVC. It’s always a good idea to check the specific material before using it.

That’s so true! I’ve seen PVC parts become brittle after exposure to brake cleaner. It’s definitely a risk.

Polycarbonate is slightly more resilient, but it can still suffer from chemicals. Always test on a small area first!

Good point! It’s definitely a good idea to do a patch test before going all out.

What about nylon? I use it often and haven’t seen any issues, but I wonder if brake cleaner would affect it.

Nylon usually holds up well, but prolonged exposure could weaken it. It’s always best to apply cautiously.

I’ve never thought about the type of plastic! So complicated. Who knew cleaning could be this risky?

It’s a good reminder that not everything works for every material. Always read labels and do your homework!

Agreed! And if in doubt, consider using soap and water for safer options.

12

Why does everything have to be so complicated? Can’t we have just one cleaner for everything?!

LOL, right? It’s like a cleaning conspiracy at times!

Does anyone have experience with acetone? I’m wondering how it compares for cleaning plastic parts.

15

Acetone is even harsher and can dissolve some types of plastic entirely. Definitely steer clear unless you know what you’re dealing with.

16

It’s funny how a product designed to clean can actually destroy things. Makes you think about unintended consequences.

17

Totally! It’s like a cautionary tale in every can of cleaner!

I would suggest using isopropyl alcohol! It’s safe for most plastics and effective for cleaning without leaving residue. Just test it on a small area first.

I’ve had great success with vinegar for a non-toxic option. It works well on plastic and doesn’t cause damage.

I agree with belindashaw about isopropyl alcohol. It dries fast and helps remove grime without hurting plastic. I’ve used it many times without issues.
