The Chemistry Behind Pystene Descaling Products

Citric acid is particularly effective because:

1. It forms complexes with metal ions (chelation), which helps pull minerals away from surfaces
2. It has multiple acid groups that can react with scale deposits
3. It's strong enough to dissolve scale but mild enough not to damage many surfaces

Lactic acid is particularly effective because:

1. It has good penetrating properties that help it work into thick scale deposits
2. It tends to be less corrosive to metals than some stronger acids
3. It's effective at removing both mineral deposits and soap scum
