It’s the most aggressive scrubber you can buy. It does rust though so be careful with that…
Also, it can actually scratch glass (even un-rusted)…very fine lines, much finer than what a razor/ fabricating debris can do. Almost invisible really…but they can show up
Do agree. I have seen it. Of course some guys are scratching windows with soft terry towels. It is NOT the wool or cotton towels that are scratching. Glass is becoming more problematic.
Look for some fascinating info at the IWCA convention this February. I really wish I could be there!

Warnings
Ammonia solution
Non-porous surfaces, such as metal, glass, and plastics
Gives off intense fumes, dissolves brass (including the brass ferrules on paintbrushes and airbrushes), blackens aluminum, and should not be used on wood
Isopropyl alcohol, AKA rubbing alcohol
Both non-porous surfaces (including plastics and unvarnished, unpainted wood) and clothing
Has no common side effects, but infrequently causes irritation and redness on skin. As with all of these products, avoid topical contact
Denatured alcohol
Non-porous surfaces, including plastics and unvarnished, unpainted wood
Contains methanol (a poison)
Acetone
Non-porous surfaces, such as glass and metals. This is so strong it will not require much scrubbing (perfect for airbrush nozzle tips)
Gives off intense fumes—use in a well-ventilated area. Not safe for plastics or synthetic fabrics
Lacquer thinner
Non-porous surfaces, such as glass and metals, and unvarnished, unpainted wood
Toluene and methanol are toxic; toluene can have long-term health effects. Look for thinners that contain ethyl acetate instead of toluene. Not safe for plastics
