Best answers to questions should be directed to the folks at Gunzilla. Then....you should always read any warnings and/or instructions. I've seen and heard many things on the internet for anything. Dissolves plastic....do not store in direct sunlight....etc. Well....one thing I can say is that it won't explode in your hands. Honest truth. I don't know how I got by for 20+ years without it actually. I bought too many products and spent too much time using them for the same reasons I use Gunzilla now exclusively. Honestly.
My Glocks almost take care of themselves. But I've put Gunzilla to the tests with the AR15s and Ruger 10/22s which are about the most fouling and lubricant dependent firearms I own....................and it has not only made my life easier on cleaning, but it has raised my confidence with reliability. Look back several years here on the forum and you'll find I was a skeptic at first. Times change.
