24" deep x 36" wide shelves, looking to store my pads and gear

I use clear plastic tubs with locking lids.

I use the 16qt and (I think) 28qt sterilite clear plastic bins. I mainly stick with the flat top (non-latching) lids so there’s no holes for dust to settle through.
They work well for most efficient use of space. Some of the other brands have odd shapes that don’t do anything to add to storage when you’re trying to make best use of your shelves.

I think my shelves are 48x18; they’re restaurant style wire shelves we got at Costco. 2 of the 28qt bins fit the long way side by side, or 4 of the 16qt bins fit next to each other sideways.

Also, FWIW, I just lay the pads flat in the bins.

I use this to store pads. Fits 2 sideways and several longways, all vertically arranged. If you need a picture I can grab one.

I had a leak in the garage this last winter and moisture got in to my bins. Some of my less used pads got molded. Since then... I put each pad in a stretchable zip lock bag with a Rechargeable Dehumidifier Packet prior in putting them back in a bin.
