what is the best(and easiest) thing to use to clean slabs...not jet wash as there is gravel in between slabs?

Answer 1

I tried power washing mine - bad idea as it's a real messy job and and washes out the gravel inbetween. I now put plenty of cheap bleach into a watering can diluted with water of course and then cover the stones and then let the weather take over. It does the job a treat. I don't use a scrubbing brush as it's a large area and too much like hard work and I have found that I don't need to do that. After that it's just a case of keeping on top of the job.

Answer 2

There's lots of proprietary products for doing this, lots seem to be citric acid based. If you don't want to use unfamiliar chemicals, try a little bleach in water and scrub with a stiff yard broom then rinse with clean water...uses calories and gets you a clean slab without using gallons of drinking water.

Answer 3

Buy one of those pump up sprayers. They are 1 and 2 gal. I put about 1 teaspoon liquid dish soap and 1 cup bleach. Wet the slabs first with your hose. Pump it up, spray it on,and let it sit for about 30 minutes. Then rinse well with hose.

Answer 4

Use a product called Patio Magic. Mix it in a watering can, water it on and leave it. It naturally eats it's way through the dirt and grime. You should not wash it off, what could be easier.

Answer 5

Use a solution of Armillatox (which is a natural product) and a stiff brush.
