Hi you lot, I need to pick your brains and apologies if this question has been asked previously.
On occasions I get asked to wash patios which is nice for the money, but is not a job I particularly enjoy, apart from getting filthy (and aching back), I sometimes find the end result varies.
I am using a Honda 200psi petrol jet washer (a step up from the petrol Karcher 3000GS I previously used). I don't use any pre-treatment, is this where I'm going wrong as I have seen before on these forums mention of "Hypo" (I presume Sodium Hypo-chlorite), and laundry washing powder. What's best and is the Hypo in a powder or liquid form and how is it applied? (ie. quantities, time left on before washing etc.). Being a bit of an environmentalist, I have also seen a product called Algon organic, has anyone got any experience of this product?
Cheers, Pedro
