clean copers with Dry Treat Skanvenja

[jack620]

I need to clean the cement residue off my bluestone copers. I pre-sealed them with Dry Treat Stain Proof and I'm worried that acid washing with damage the sealer. Dry Treat recommend using their product Skavenja (they would, wouldn't they?) which is a non-acidic efflorescence remover. Has anyone used this product? Does it work? I haven't priced it yet, but the Stain Proof was $67 a litre, so I'll bet it's not cheap.

I have a product called Cleaner 304. Great for removing any type of grout haze. Comes in 5ltr. and 20ltr. bottles. Not a harsh acid like hydrochloric. Its a phosphoric/nitric mix which won't burn the pavers.

Drop me a note if you think i can help :2tsup:

Thanks. I actually have about 10L of that stuff left over from cleaning my house bricks. I think I'll just use that.
Cheers
