Here's what's in my kit:
• Microfiber cloth (to blot liquid from a carpet)
• Soda water (to dilute a carpet stain before blotting)
• Spray bottle with 50:50 vinegar water (for any sticky surface)
That's it! I make sure I have these things close by so I can quickly dispatch a carpet spot or sticky countertop without much fuss. Speed counts, so address the spill right away, but remember to do it gracefully. Try to avoid adding to the embarrassment of the spiller, because we've all been there!
