You’ll need to do a little more than sprinkle some baking soda over your patio chairs to make them look new again, but don’t worry — it won’t take too much effort. All you will need is 1/2 cup of baking soda, warm water, and dish washing liquid. Mix the 1/2 cup of baking soda with a squirt of dish washing soap in 1 gallon of warm water. You want to take special care that the water is warm, not just room temperature or cold, since warm water helps loosen caked grime and dirt. You also want to use a drop or two of soap and no more than that. Adding too much soap can leave behind a sticky residue on the furniture, which will then require you to douse it with water. This can wreak havoc on wooden pieces in particular, which don’t like being exposed to too much moisture, or else they can warp or splinter. You also don’t want to do this on metal furniture, since the baking soda can corrode it.
Once you have your cleaning solution, use a soft bristle brush to apply it to the furniture, which will help remove more dirt and dust than a simple sponge or cloth. Then rinse it off with your hose or a damp microfiber cloth. Ensure it dries in the sun thoroughly, and you’ll be left with a sparkling patio set.
