…from the neighbors. I live in an apartment, and the harsh chemicals and solvents caused some complaints from the neighbors when I cleaned several of my guns at once. I have only treated my pistols at this time, and I am blown away how easy clean up is. What used to take a 15+ patches now takes 3-5 once they come out carbon free. Then I reheat and repeat the application…no more burning of the skin and eyes and no more stink from harsh chemicals. I can’t wait to see the results on my black power rifles.
