FAQ

Can I run a richer mix than 20:1?

Stay with the official ratios unless the product label specifies otherwise. Over-concentrating can clog the metering tip.

How much concentrate is 20:1 in metric?

About 47 mL of concentrate topped with water to 1 liter for the BOSS jar.

Do I need warm water for the BOSS foamer?

Warm water helps dissolve thick soaps, but ambient water works as long as you shake the mixture before use.
