Scrape off any excess droppings from the cushions and then wash the spots with soap and water, being careful not to spread the stain.
I read that you can make a mixture of 1 TBS vinegar, I TBS dish soap and 2 cups of warm water. Put the mixture in a spray bottle and spot clean by dabbing with rag until clean.
Dish soap, scrubbie sponge and garden hose. I do it all the time as I feed the birds.
So welcome John! Enjoy your summer! 🌞😎🍍
