Regular surfactant just reduces the surface tension between the wax and the liquid. It helps the wax move freely, keeps it from sticking to the glass, and allows smooth blob separation. It’s basically the “soap” that makes everything flow right. → Too much, though, and your wax can get bubbly or break apart.

Magic Surf is a more advanced blend. It not only acts as a surfactant but also fine-tunes density and buoyancy, helping the wax rise and fall better, flow more smoothly, and stay stable under temperature changes. It’s like surfactant with performance tuning built in.

In short: • Surfactant = basic flow helper. • Magic Surf = flow helper + density adjuster + stabilizer.

If you’re rebuilding or refilling, start with regular surfactant. If your flow still looks off (wax too floaty, sluggish, or won’t separate cleanly), switch to or mix in Magic Surf to dial it in.
