RustBlast is dyed, and the dye color varies depending on what is available. The dye is there for one reason: so you can tell RustBlast apart from KBS Klean, which is clear, when both are sitting in spray bottles on the same bench. One color of RustBlast is not better or stronger than another.
Why RustBlast Has a Dye in It at All
Both KBS Klean and RustBlast are commonly decanted into spray bottles for application, and they do completely different jobs in the KBS 3 Step System. KBS Klean is a diluted water based cleaner and degreaser. RustBlast is applied full strength and is an acid etch. Mixing the two bottles up means either degreasing with acid or trying to etch with soap, and neither gets you a coatable surface.
KBS Klean is clear. RustBlast is dyed. That is the whole reason for the color.
Label Your Spray Bottles Anyway
The dye tells you which bottle is RustBlast. It does not tell you what dilution the KBS Klean in the other bottle is mixed at, and that ratio matters a lot: 1 part hot water to 1 part KBS Klean for heavily soiled surfaces, 5 to 1 for moderate, 10 to 1 for light, and 25 to 1 for non ferrous metals. Write the ratio on the bottle. See KBS Klean dilution ratios.
What the Color Does Not Tell You
The dye color carries no information about strength, age, or which version you have. Please do not assume one color of RustBlast is better than another. RustBlast is always applied full strength to a dry surface, whatever color the bottle looks like.
