What did you tell Walther when you spoke with them? What was their reason for not covering under warranty?
This times 100.The guide rod looks like a banana. If it were me, I'd replace it before shooting the gun.
What exactly did Walther tell you when you talked to them?
"Purchased a PDP F-series 3.5" in March. Just cleaned it up this
week and found various issues. Never shot it so all observations are
visual so far. (1) barrel finish shows defects that there are discolorations
on feed ramp and barrel crown area. (2) Discolorations (oxidization?)
from locking block, trigger bar, and metal mechanism next to the ejector
bar. (3) Slides shows many coating defects (cerakote loss?) (4) gritty
trigger feel when the trigger is pulled. (5) recoil rod is longer than
frame causing the slide to tilt up when put together. Pictures available
if needed. Please help. Thank you. /CP
Did you put the guide rod in the ultrasonic cleaner?My original web support request after the ultrasonic cleaning: "
Question or Comment:
"
They then asked me what oil I used. I told them that CLP and then ultrasonic cleaner. Eventually that is the reply I get. Did I use the ultrasonic incorrectly? How come my Canik (gray coated) survived but not Walther? Thanks /CP
I did put the recoil rod/spring in the cleaner.Did you put the guide rod in the ultrasonic cleaner?
I used this cleaner/solution approach on my Canik and some of my AR parts. Unfortunately only the Canik is coated and all other parts are just nitride finish (no coating). They all had no cosmetic issues afterward. So far I agree with your view, there seems no obvious benefit of using ultrasonic cleaning then cleaning by hands and old fashion oil. The dilution percentage, temperature, and timer settings are obtained from the forum/web. The cleaner I have is from Amazon (Vevor brand) that no particular instructions for firearm cleaning.I don't use ultrasonic cleaners, and I've never used Simple Green on a firearm. Does the manual specify against the use of whatever chemicals are in Simple Green?
While I don't personally see the need to use an ultrasonic cleaner on a firearm, much less a new firearm, if this can occur while using common cleaning supplies, it should be known (which it now is), and it should be advised against.
How many other pistols have you subjected to this process? I've been wondering what type of finish/treatment they have been applying to the F-Series pistols made here in the US. Unfortunately, at least the outer finish looks like a step down in quality, as I recall members here using ultrasonic cleaners in the past for Walther pistols made in Ulm with no negative results. I remember a thread in the past where I mentioned that I would have preferred that manufacturing stay in Ulm rather than here in the US. This may be an example of why.
I don't see too much of a bend on that guide rod, but if there is one there, maybe someone can explain to me how an ultrasonic cleaner, the chemicals inside of it, or 140F of heat could make this happen. It looks like a similar recoil spring assembly to the one in my P99c, and I'm pretty sure I've gotten it around temperatures way hotter than 140F. The outer finish on these pistols doesn't do much as far as corrosion resistance (assuming that F-Series slides and barrels are nitrocarburized like the pistols made in Ulm), so I would probably just take the rest of the finish off and leave it.
I would definitely get this pistol to a gunsmith for inspection before even loading it, much less firing it. I'd ask the gunsmith to pay close attention to the channels on the inside of the slide. A loose piece of finish sticking out of the striker channel/breechface, or a loose piece of finish causing the firing pin block to "stick" could be very dangerous here, and could also cause malfunctions in the future.
I've been using "normal" methods of cleaning firearms for decades. I've never had issues due to using more old-school methods, and while I'm not making any excuses here for Walther, I don't see the need to use an ultrasonic cleaner on a firearm. They don't need to be spotless. At least leave the plastic parts out next time.
Are you sure about the dilution of Simple Green and water, and the temperature of this liquid. I noticed that the finish was also taken off of the steel recoil spring and locking block in the picture.
I personally would not run with the coating is not as good on the F-Series just yet.Are you sure about the dilution of Simple Green and water, and the temperature of this liquid. I noticed that the finish was also taken off of the steel recoil spring and locking block in the picture.
I have to agree 100% with everything balance said above. On the Simple Green warning label it states to test it on a hidden spot to make sure there is no reaction. If this was me I would chock it up as an expensive learning lesson and have a good gunsmith look it over. If it checked out ok I would send the slide / barrel out for PVD coating and replace the small parts that were affected with either upgraded ones or new oem ones.I don't use ultrasonic cleaners, and I've never used Simple Green on a firearm.

I did use the compressed air immediately dry them thoroughly when I took the guns out of the zip-lock bags. However, I only had "field stripped" the pistol (slide, rod, barrel, and frame) and put them all in one zip-lock bag when cleaning. The "corrosion (are they corrosions?)" is another concern I had when I was taking pictures, but they seemed "gone" after I oiled them(??).If the whole gun was put into the ultrasonic bath you’ll want to detail strip and wipe all metal with your CLP. I’m assuming that’s the case because of the locking block corrosion. Hopefully the damage is cosmetic only. Even though the guide rod and recoil spring are probably safe, I’d replace them.
I don‘t have an ultrasonic cleaner or use simple green but did a quick search over on the tubes. This guy suggests a special formulation of simple green, distilled water, compressed air to dry, re-lube. Not sure of your process or if it would have made any difference but worth a watch for future reference.
Simple Green Ultrasonic Cleaning (firearms): Life Saver!
I'll admit that I'm ignorant to most things regarding the topic of cleaning firearms in ultrasonic cleaners.I personally would not run with the coating is not as good on the F-Series just yet.
That may turn out that case but this could just as easily be a case of a well-intentioned but overzealous or not quite perfectly performed cleaning gone bad.
