Hey Guys

Have a drive way that is down years, I bought house about 8 years ago. I regularly cleaned with my electric power washer but never got it really clean. I bought a more powerful one this year and spent 2 days really cleaning it, took a mountain of muck off it but still the blocks have black stains on them and also white dots etc.

My friend have a huge petrol washer so just got that and spent the last couple of hours washing it, also added in some paving cleaner stuff I got for karcher cleaner. Took some more dirt off the blocks but still dirty.

Any idea's what I could do next to clean them? is there some sort of cleaning fluid I can put on it that will clean off the ground in dirt?
