First, start by washing it. Hot soapy water and a scrub brush will remove dirt and loose rust and paint.
Next, tire check. Flip the wheelbarrow over and check the wheel, if you've had a leaky tire a little more soapy water can help pinpoint the leak. Look for bubbling and listen for hissing. Then you can repair any holes and reinflate.
Once the tire is set, flip it back over. Sand any chips or slivers from the handles, making sure that they're in good shape for new year.
Wipe off any sanding residue and spray them with polyurethane to seal them up.
Now for the inside, make sure that the inside is dry and that all of the loose rust is removed. Then, spray the bed with some rust inhibiting spray paint. This will keep the rust from spreading and seal it up.
Just a few easy steps that you can take to make sure that your wheelbarrow is set for next spring. I'm Mrs. Fixit and it's just that simple!
