How do you clean stone pavers?

I had hoped that all I would need to do was hose down our sandblasted granite pavers but the grout is attracting some dirt, particularly as our garden isn't established yet. I think I need to invest in a pressure washer.

 

We recently used baking soda to get a stain off our sandblasted granite paving. It worked reasonably well. Just leave on for a few hours and then hose off. I believe that the quicker you get onto it the better your results will be. - Jason

 

I've noticed our new natural stone pavers have some stains on them. I presume it is the oil from guests applying sunscreen near the pool. I've tried blasting with the pressure hose but it didn't have much of an effect. We're also finding the grout gets a little grubby and the pressure washer alone isn't doing the job. I'm wary about using any chemicals for fear of ruining the stone. I am starting to think we made a mistake when the paver advised not to seal the stone. The paver suggested that it wasn't necessary, in fact that it was detrimental as the stone would have a permanent "wet-look". - Joker

 

Just wondering what the PSI rating is of your pressure cleaner that you're using? I find the more powerful works better on grout or other stone work, cement, general cleaning. I think my Gernie is around 1700psi? And it works fairly well. - Robessa
