Pressure washer - detergent ?

[Deleted User]

Sorry if this is a really dumb question - it's just that I've never used a pressure washer before. After looking at prices, have decided to hire one for a weekend and see how it goes. But I'm just not clear whether or not I need to buy some detergent for it?

I need to pressure wash some outdoor flags, and 2 driveways - both for the first time and they're pretty grubby. So do I need detergent?

Thanks.

There is no need for any thing other than the water itself.

It might help if you wet the area you are going to clean about thirty mins to an hour before hand.

That's a relief ! And thanks for the tip.

No detergent, but a very stiff bristled brush will be useful if they're very grubby.
