Using this bun pan rack is really easy. First, just roll it to the spot where you need it using the smooth - moving casters. You can lock it in place with the caster brakes when you find the right position. Then, start loading your full or half - size sheet pans onto the ribbed slides. The slides are spaced 3 inches apart, so it's simple to fit the pans in. When you're done using the pans, nest them together to save space. As for maintenance, keep it clean by wiping it down with a damp cloth regularly. Avoid using abrasive cleaners that could scratch the aluminum surface. Check the casters from time to time to make sure they're moving freely and the brakes are working properly. And that's all there is to it! With this rack, you'll have an efficient and convenient storage solution for your sheet pans.
