Good thing I had seen any advertising for this product, otherwise I would not buy it because I would never have believed in life that one can achieve such cleaning results with a little water and without detergent. But obviously there are sometimes wonder, at least in the plaster area. I have so in record time my old washing machine, the relocation caused a year in the garage was, cleaned spotless. The now shines like new! And with just a bit damp cloth. So I'm just excited and looking forward to the new fields of application. This purchase I can only recommend. Remains to be seen how durable the product is and how long to keep its properties.
