As noted there are a number of previous discussions across the community on the products with the KOH branding.
Canstar’s award based on product satisfaction/popularity noted.
It may be worth reviewing,
Like many other branded cleaning products delivered as a liquid the consumer is paying for packaging/container, a small amount of a chemical, and mostly water. Marketing and promotion costs may also be significant.
I do wonder if there is true value in commercially produced home cleaning products when it’s possible to replace many with simple home products for a fraction of the cost.
Home cleaning using products based on eucalyptus oil, sodium hydroxide, white vinegar, solid soaps (sodium hydroxide), liquid soaps (potassium hydroxide) etc all do different jobs.
