Time for new radio knobs

Post by WingAdmin » Wed May 30, 2018 6:01 pm



I was rebuilding my front brake master cylinder yesterday. When I was finished, I sprayed a bit of brake cleaner on the bottom of the master cylinder, to clean up some brake fluid that had gotten out, to prevent it from dripping on my plastics after I removed all the drip towels. Some of the brake cleaner missed, and landed on my stereo. I wiped it up immediately...but it dries fast, and now my radio knobs are permanently stained:

I've tried several different cleaners, and nothing is touching it - it's into the plastic. Oh well...I've ordered some new knobs to replace them. But I'll be more careful in the future with brake cleaner!!

Wow, that set in fast. Since you're getting new ones, and have nothing to lose from an experiment, I wonder if you were to wet a rag with brake cleaner and wipe it across the top of the knob maybe it would uniformly spread the "effect" of the brake cleaner and there wouldn't be spots that were noticeable. Instead you'd have a solid look of whatever effect it would have.

Brake cleaner !! - or brake fluid - best thing to do is have a spray bottle full of water at your side - this will dilute the chemical and because water is a inert substance if will do your bikes plastics no harm what so ever !! - I always keep a spray bottle full of water near by just in case :o :o :o - so I don't get caught out - we all know what solvents do to already old abs plastics - yes ?? by spraying with water it will defo dilute it … :D :D :D :D

Just - passing on a good tip - here to fellow wing owners … :D :D :D :D

It's odd, because I have NEVER had this brake cleaner do anything to ANY other plastic on my bike before. In fact, in the picture, you can see the fuel door flap right next to the knobs, which is clearly unpainted ABS, and also got splashed - but was completely unaffected.

Brake fluid will destroy ABS pretty much on contact, this is well known - which is why I'm so careful doing brake work on my bike.

Does that not really get your back up, you cover everything, and use cleaner to prevent plastic damage, and tadah.
If at first you don't succeed, hide the evidence.

The Panasonic radio knobs are probably suspect to UV degradation or some such and has changed the composition.

I suspect this is exactly the case.

Just for fun, try spray painting the old damaged knobs flat black, and then once dry, go to your local Hobby Lobby type store and buy some stick on jewels and use them to mark the dots on the knobs.

Jewels like these are what I am thinking :

Yeah, mine had chrome ones on it when I first got it. I ripped them off (along with a ton of other blinding, useless chrome in the cockpit) as it blinded me every time the sun was out.

My 2002 1800 previous owner must have spent over $4,000 on pretty chrome

after I bought it, it did not make 10 miles before I had to stop and use a knife to peel most of it off the top of the bike. that crap was everywhere one could find a vendor that sold chrome.

i just do not understand that mentality.

I was blinded by the reflections of the sun at almost any angle you could ride away from the sun's glare.

Mine was even weirder that that, I had a TON of chrome, but every piece of chrome had wood grain over it. . . . . . ?

I have found that some of the cheaper brands of brake cleaner contain acetone. Found out the hard way. I only use CRC brand. Just saying.

This is the same NAPA brake cleaner that I have been using for years, never had it do anything like this before to ABS!
