I just looked at my can of Wipeout. It's old, last can of a case I bought a long time ago. But it says "contains no ammonia" on the front. Not sure if I had ever read the back before. Probably did, but long ago forgot. Anyway... On the back it says it's effective for 24 to 48 hours and will cause no harm when left in the bore that long.
Course, I think tobacco companies used to say the same thing about smoke in your lungs, so... But, I've been leaving it in for long periods, for I'm not sure how long but has to be 15 years now. No issues I've ever become aware of.
Think I mentioned earlier, when it comes to hard carbon, I still resort to JB though. That stuff needs some mechanical action to break loose. Have never found any chemical that will remove it. But, even in my very over bore hotrods, I've found regular soaking with Wipeout, I rarely see that kind of hard fouling that requires brushing and or JB. Not never, but rarely.
