IK foam sprayer users? cleaning advice requested

[icj_45e]

Hello all, just purchased my first IK Foam 1.5 sprayer for applying Adam’s Wheel & Tire cleaner. IK says to empty the sprayer and rinse with water after every use.

Any IK foam sprayer users here? Do you really have to rinse with water after every use?

Thanks
