Here’s a home maintenance tip I borrowed from the equestrian world- When your outdoor cushions start looking dirty, stained, or shabby, load them up and head to the nearest car wash. Most car washes provide strong clamps on the wall for floor mats that work great to secure your pillows and cushions and keep them off the ground. (If you DO happen to have horses or livestock and you haven’t tried this trick, it’s fantastic for cleaning saddle pads, winter horse blankets, and other things to large, bulky, or disgusting for a washing machine)
The softened water and high pressure spray at a carwash will return gross lawn furniture seat cushions to sparkling in minutes. I’ve even had great luck doing this with cushions that were starting to mildew from being wet and shady too long- one trip to the car wash and letting them fully dry in a sunny spot in my yard had them looking and smelling like new again.
This trick also works great to clean thinner-style dog beds (but definitely NOT the cedar stuffed kind!).
Keeping your car dry on the trip home can be the hardest part. I use an XL Tub Truck (aka a “muck bucket”), but using a laundry basket or even large trash bags should protect your car.
