Think Twice Before Using WD-40 In These Spots Around

Door Hinges
While WD-40 might stop a heavy-duty hinge from squeaking for a short while, it doesn't contain enough lubricant to work long-term. It can also attract dust and debris.
For a standard hinge, pull out the pins, clean and spray them with silicone spray, then reinstall them. Clean rusty hinges with a penetrating lubricant like PB B'laster.
WD-40 isn't suitable for use on a sticky lock because its lubricating agents can't get inside to loosen it. It also collects dirt that will gum the lock up again.
Instead, use a Teflon lubricant, which remains dry and doesn't attract dust. It's also water-repellent to prevent rusting, which is especially useful on exterior doors.
While there's some debate, many people, including bike experts and repair shops, claim that using WD-40 on bike chains is not good as it can clog the chain with dirt.
To be safe, use WD-40's Specialist BIKE lubrication products from Amazon or a Teflon oil like Tri-Flow, recommended by bicycle repair shops and riding gurus.
While WD-40 is effective for cleaning tile and grout on kitchen floors, avoid using it to clean a tile countertop in your kitchen — rather, clean it with baking soda and vinegar.
Use diluted isopropyl alcohol instead of WD-40 to loosen a sticking game controller button or keyboard key, as the solvents in WD-40 corrode certain plastic parts.
