Weeds and block paving

Good evening all.

It’s that time of year when weeds start to appear in cracks within block paved areas.

What is the best, practical method of killing these weeds please?

If it’s a weed killer as l would expect, what do you use?

TIA

Sodium Hydroxide granules aka caustic soda or drain cleaner.

Just brush the granules into the cracks & nothing will grow.

Whatever you do, don't use it as a general weedkiller in your garden proper - it will render the soil infertile!

Thank you for your suggestions. Happy to try both salt and caustic soda.
