brake kleener on titanium

A GM dealer's guy tell me today that he saw a service note from General Motors tech dept. to do not use brake kleen on titanium valves (corvette) , it could altered the titanium property. Do somebody heard thing like that before ?

right inside the manley box there is a warning to not use brake clean on there titanium valves!
same deal...

 

could somebody elavorate on this anymore?
If this is true then I have been doing wrong for 20-25 years.....
Not to be a wise guy but to find more facts !

I have been know to use brake clean as a dish washer before!

 

I'am like JP I have been using it for years.also use carb cleaner..will carb cleaner hurt? Dave

I'll try to have this tech note from my GM dealer and i'll post it.

 

What you say is correct. Cleaners with chloride/chlorine compounds can get into small surace imperfections and machining marks, and can actually promote the onset of surface based fatigue cracking (which Ti likes to do anyways). In the aviation industry for example, there are very clear guidlines for washing Ti parts. Supposedly years ago Cosworth was having a rash of Ti component failures which were all eventually linked back to contaminated wash solvent. The same consideration does not apply if the Ti part is surface or deposition coated by some other means.

 

It will be interesting to have some thought from Del-West or Victory about that !

 

Whew, I feel better..maybe...I think. I use non clorinated brake clean.

 

i'm too poor to run ti parts.... but i use lacquer thinner in a spray/squirt bottle instead of brake cleaner

lacquer thinner vs brake cleaner?
-cutting heaviest of oil, grease and grime- lacquer thinner = brake cleaner
-leaves no residue or oily film- lacquer thinner = brake cleaner
-smells pretty (haha)- lacquer thinner = brake cleaner
-price-$10/gal @ wal-mart vs $2-3/can @ most places- lacquer thinner > brake cleaner

may not solve the ti parts problem... just thought i'd throw this out there. and since it's not in a can that is half full of propellant... it seems to last a helluva lot longer that brake cleaner too

 

brake kleen

in addition to the brake kleen with chlorides, watch out for magic markers they have chlorides in them too.. i know i made that mistake...

 

does carb cleaner have that in it??Dave

Broke something with a magic marker?

 

You guys are worried about spraying break cleaner on your valves, I'd bet you guys would blow her up before that even becomes a factor.

 

And I believed I had found why I was blowing the engine

 

marker

there are chlorides in the marker, i used it on areospace Ti... a no no,, they had to scrap it..

 

WD40, is recommended.
