Is the 4-pack worth it over spray cans?

If you use WD-40 regularly for soaking, dipping or refilling spray bottles, the four gallons cost less per ounce than aerosols. For occasional use, a single spray can is easier.

Do the gallon cans come with a spray nozzle?

No. The Smart Straw is on the aerosol cans. Gallon cans are for pouring, soaking or dipping, so plan on a spray bottle or tray.

Can I use it on guns, bikes or power tools?

It works for light lubrication and moisture displacement on bikes and tools. It is not a substitute for gun oil or bearing grease, and it can leave a residue.

How should I store four gallons?

Keep the cans sealed, upright and out of direct sun. WD-40 has a long shelf life, so the pack lasts years in a garage or shop.

When is the price lowest?

Bulk packs tend to dip during store promotions and holiday sales. The current best is $129.00 at The Home Depot as of November 6, 2026.
