I had to clean patio paving last year

Picked up a drum of milking parlour detergent from local co-op and brushed it in.

then powerwashed an hour later

Shining aferwards

Thanks. I have flower beds adjacent to the patio, would that detergent do them any harm? I guess not, as its for a milking parlour

Citizenpain

Possibly would .... It did kill some grass for me..... around the border -- not much though

jrby

thanks for the heads up. need to look for an alternative or else it will have to be elbow grease!

Try the power washer without detergent, works for me.
