Many thanks, will give it a go

What sort of dirty is it? When we milked the collecting area could get greasy and we used brick acid to return its 'sharpness'. Otherwise anything hot thrown on it will help....hypochlorite is good.

I use hypochlorite mixed with shampoo. The shampoo makes it foam so it's less likely to run off. It also makes it smell nicer if you're in public areas. It needs time to work so best done on a damp day or it just dries out.

Will a rotating nozzle not clean it?

Anything acid is going to Attack the surface, so I would not go anywhere near milkstone remover

I like this idea, would you put it on with pressure washer, or spray it on with a hand held sprayer ?

I put it on with a hand held sprayer but through a pressure washer at low pressure should also work well.

 

[Pennine Ploughing]

I have both, so will use hand held sprayer, many thanks

Liberal sprinkling of council road salt will leave you with a sparkling new surface! If a tad rough!

A hot pressure washer if you can borrow one of someone It’s amazing how much better they are at cleaning compared to cold water

Brick acid

To add acid is very dangerous please use appropriate ppe

I've cleaned some hard used lambing shed floors back to very presentable condition with a hot water, high pressure low volume pressure washer, no chemicals. I'd hire an electro-diesel unit with a ceramic bead rotary head.

Kilco Ecofoam is good as long as you have a foam attachment on your pressure washer
