HITACHI Washing Machine Tub Cleaner SK-1500 for a clean washing machine tub - Brand: HITACHI - Contents: 1500ml - Purpose: Washing machine tub cleaner - How to use: Add to the washing machine - Notes: Instructions for use are included Thank you for viewing. I switched from a Hitachi washing machine to a TOSHIBA one, and I tried to use this cleaner with my TOSHIBA drum-type washing machine. I peeled off the plastic wrap, but I haven't used a single drop. Before putting it in the washing machine, I checked again to see if it was compatible with the TOSHIBA drum-type, and it turned out it wasn't, so I stopped using it.
