If Used Water and Absolute Water are mixed in exactly equal weights, what precautionary ruling is reported in the supplied commentary?

Water Mixtures: When Does Another Substance Dominate?

• Absolute Water is treated as dominant, so Wudu is valid.
• As a precaution, Wudu with this mixture is not treated as valid.
• Dominance is decided only by color, taste, and smell; weight is ignored.
• When both are equal, the mixture automatically becomes Absolute Water.
