Clorox isn't sold directly in outlets in the UK, though a limited range of Clorox products are available - you can see some here. There is also a company called Alibaba that has Clorox products, and you can try contacting them too.

If you want to buy a wider range and be sure that you are getting the genuine product, the best thing would be to contact the company directly. You can do this here - it doesn't look as if you can order directly from the website if you are outside the US, but if you contact them they can tell you what the options are.

Clorox did have a UK division at some point, but it doesn't seem to have one now. However, it's quite possible that the identical products are sold in the UK under another name - this happens quite a lot, and is something else they can tell you about. Good luck.
