Caustic soda?

I really cant see why a pressure washer wont do the job.
Main problem with bleach etc. must surely be the run off, if near the lawn or plants.

Are we talking about caustic soda, or the old fashioned washing soda?

 

Caustic soda

 

Wouldn't even know where to buy some?

 

I get a lot of fall out from the local few hundred yards away steel works, so power washing does not remove the greasiness, it is slow and water consuming when metered, I can do 6x6 slabs with 1 lot of water, whole back garden is all hard landscaped, so paths and 2 patios, would be done with 3 or 4 lots of bleach water, then hose down all to run into gravel areas.

 

I dont think we have one of those around here, is it similar to Toys R Us?

 

Could try Nitromors.

 

This sounds like me bathing the dog

 

I'm with the bleach brigade

 

Isn't "stardrops" disinfectant?

 

No I don't think so, it is a gentle detergent. I've used it for long time around the house and garden, think it has been around for donkeys years, cheap as chips about a quid for a bottle and very versatile. Works well on the fungusy mossy build up on patios without the bleachy smell. And no damage to plants.

Well just to confuse the issue you can now buy both.

 

Ooh, I can't keep up
