I love these products, the cloths work really well and leave a streak free clean on many household surfaces such as glass, tiles, stainless steel.
The black diamond sponges are excellent on oven doors with a little water, effortlessly removes built up baked on grease.
The koh product is just brilliant for cleaning kitchens surfaces with no sticky residue like some other products leave.
I would totally recommend this range of cleaning products to anyone serious about cleaning and caring for the world in which we live.
