Should be a little more upfront and admit it is you selling this product. Think that makes your recommendation null and void. Sorry.
Bit expensive isn't it 
Hi Garyj
Many thanks for your comment. Well I am not directly selling it, its my partner who is selling it, and reason for the price, is because its highly concentrated product, for example if you use it without any dilution 500Ml can clean two medium size conservatory with ease depending on condition.
