Pressure washing is a highly effective method for cleaning block paving driveways. By using a pressure washer, you can remove things like dirt and tyre marks. Here's how to pressure wash block paving: Start by clearing the area of any loose material and debris using a stiff broom.
Pavers look well laid (other than the ugly edging). As you have planned, start with a good pressure wash, and maybe even a gentle acid wash, and replace the sand with some fresh sand (or even better, some mortar). As other have said, some better edging will greatly improve it.
Try using a paving cleaner or weed killer first to kill weeds and remove ingrained dirt. Pressure washing block paving should be used to gently clean and rinse the surface. It should not used to blast the paving clean at maximum power & force.
On the contrary, warm, soapy water works just as effectively. Empty some washing up liquid into a bucket with warm water. Next, dunk a sponge or brush into the suds and start cleaning your paving slabs, working in a diagonal motion to avoid scrubbing too harshly on the joining compound.
White vinegar is one of the best solutions to removing algae growth from your block paving. White vinegar is not only eco-friendly but a powerful cleaning solution too: Vinegar will effectively kill and remove algae. It also doubles up as a weed killer (ideal for the gaps between the pavers).
The most tried and tested way to get rid of moss or green algae from block paving is with bleach. This versatile cleaning agent works on a multitude of stains and problem areas, helping to restore your decorative paving to its former glory.
1000 to 1500 psi pressure is easy to mange and will not cause damage to pavers and paving stone. A low pressure washer is also safe for mortared flagstone and slate patios and walls. You will have to be more careful as the mortar between the joints can crack and be washed away.
A weekly rinse with a jet wash, power washer or even a bucket with some washing-up liquid to create some soapy water will make the maintenance of your block paving over the warmer months far more manageable.
For a household solution, baking soda is safe to use on natural stone, and it kills spores. Be sure to brush the baking soda away within 24 hours for a clean and moss free area. For a tougher natural method, mix equal parts vinegar and baking soda to eliminate growth.
Concentrate spraying sealer over the joint. One liberal coat will seal, protect and lock down your interlocking concrete paving stones. Excess sealer on the surface must be back brushed or back rolled into the joints. A second coat should be applied to give additional protection and increase gloss.
To remove general dirt and debris, regularly hose down your paving and sweep with a hard-bristled outdoor broom. When the paving is heavily soiled, scrub the area with a hard-bristled brush or broom and a general-purpose cleaner (a pH neutral/slightly alkaline, non-abrasive cleaner can be used).

One of the most important things to remember when pressure washing your block paving is to use the correct amount of pressure. Too much pressure can damage the paving, while not enough pressure will not remove all the dirt and grime.
I'd recommend diluting some liquid pool acid, apply it sparingly to the stubborn areas, let it stand for a few minutes, then rinse it with a fine spray from your hose until you feel that's all flushed away. Going over it again with the pressure cleaner should have it looking a treat.
