Bissell FreshStart Clean-Out 3556 cleaning solution for CrossWave, 2000 ml

Bissell FreshStart Clean-Out 3556 — wet & dry floor washer cleaning solution for the CrossWave; 2000 ml bottle. This one cleans the machine, not the floor: after dozens of runs a layer of grime and detergent residue builds up in the tank, the hose and under the brush, and that is exactly what produces the stale smell on the next start. A clean-out cycle roughly once a month is the only odour prevention that works without taking the machine apart.
