Could I borrow a pressure washer for a weekend? (Ciudad de México)

I'm Lorenzo in Ciudad de México. I'm clearing an overgrown plot to grow vegetables, and I need a pressure washer for a single afternoon. Buying one for a single job doesn't make sense and the rental price is more than I can manage right now. If you have one gathering dust in the garage, I'd be grateful to borrow it. I'll collect it from you, look after it, clean it and bring it back on the day we agree. I'll leave a deposit if you'd like, and I'm happy to meet somewhere public the first time. If you could also show me how to use it safely, that would be an extra kindness. Many thanks, and I'm happy to answer any questions.
