How do I get rid of smell of spilled weedkiller?

Question

I accidentally spilled about a tablespoon of an old bottle of glyphosate weedkiller on the concrete floor of our back porch yesterday, while clearing out a load of garden chemicals that my dad bought decades ago. I stupidly tried to clear it up by diluting it with about 8 buckets of water (I now know that that is the completely wrong thing to do - you should absorb it to try to stop it spreading before washing the floor). I have washed the floor with soapy water, but it still has a slightly chemical smell and I'm worried that it will be toxic to the cat and/or give of toxic fumes. Anything I can do to fix it?

Weedkillers and other harmful garden chemicals are given an unpleasant smell and taste to stop people consuming them by accident.  The smell is actually relatively harmless.  You have diluted it sufficiently to avoid it being harmful to you or the cat.  You may find that the cat dislikes the smell and won't use or cross the porch.  Give it a few days and the smell will disperse.
