TSP usually removes the grease. Muriatic won't work if there's grease/oil/wax in the concrete.

Re: bbq stains on the balcony

You could also try engine cleaner from the DIY center.

Re: bbq stains on the balcony

I install and renovate quite a few terrace decks, what I find works best is dish washing liquid applied neat and scrubbed in with a stiff bristled brush. Then add a bit of water and continue to scrub then rinse off liberally with water, it may not completely remove the stain but will break it down so it will fade in the sunlight. The same technique works really well on WPC decking.

Nice. Everyone should have dish washing liquid at home. Happy scrubbing!

Re: bbq stains on the balcony

cover it in salt, then wet the salt with a bit of water. Let it sit 24 hours. The stain should be bleached out.

That is really effective on gazzilions of things too. Brake cleaner, then petrol are my follow on suggestion if that doesn't work.

So in summary:

Washing up liquid,
brake cleaner,
petrol,
light it,
piss on it.

I have done this on my patio. Worked fine. For paint stains, olive oil worked well. Followed by washing up liquid for the oil stains... Nice and clean now.

Re: bbq stains on the balcony

I've tried the dishwasher liquid trick and also tried a spot with brake cleaner but both didn't help much. As the dirty area is in a part that has no direct sun, I either need to go for something more agressive or be patient.

What kind of stains are they? Is it fat from dripped food or smudges of charcoal?

My grandma used to use a paste of washing powder left on hard-to-shift stains. Maybe you could go one further and use a paste of Vanish. She used to leave it for a couple of hours then scrape it up and wash it down. If it doesn't remove it completely, it might sufficiently break it down so you can shift it with other products.
