Bissell Cleaning and alternative cleaning liquids

[noname]

I've got a Bissell Powerwash Prowash 1698 upright carpet cleaner(cleaning liquid goes in separate compartment), Works great. The only downside is the cleaning liquid at £15 per bottle. Do i really need to use this, or is there another alternative , and if so is it as good/ will it damage the cleaner

Thanks

Go to a janitorial supplier and get something from the Prochem range of products. You may still pay £15 for a bottle but it is likely to be a bottle x10 the size of the Bissell equivalent.
