High spec job - chems for concrete, tiles, pavers?

Stains/Surfaces
1

Hi there, I’m cleaning a high spec house and looking for some advice on chems (or no chems) on what looks like concrete slabs and blocks, plus pavers. The owner doesn’t know what the building materials are but I’ve reached out to the architect for some info, so expecting a reply in the next day or two.

Here’s a slideshow video I put together:

For those interested, the white concrete is reinforced fibre concrete.
Anyhoo…
… I softwashed the house using a concrete cleaner. SDS below:
2-Butoxyethanol - 1-5%

Sodium Metasilicate - 3-8%

Non-ionic Surfactant - 5-10%

Water - Balance

And for the yellow stains I spot cleaned and scrubbed using a stain remover. SDS below:

Oxalic acid dihydrate - 1-10%

Water - 90-99%

The owner was chuffed
