Silicone Spray Lubricant, 400ml with Smart Straw, All-Weather Rust Protection Silicone Lubricant, Repels Moisture, Dust, and Grime for Rubber Seals, Doors, Windows, 1-Pack

I bought this WD-40 Specialist Silicone Spray to use on doors, windows, and rubber seals, and it’s been extremely effective. It quickly reduces squeaks and friction, leaving everything moving smoothly again with minimal effort. The Smart Straw makes application much more precise than expected, allowing me to target small areas or switch to wider coverage when needed. Once you get used to it, it’s very easy to control. It works particularly well on rubber seals, helping to keep them flexible and protected while also repelling moisture and grime. I’ve also noticed it helps prevent sticking on doors and windows. The 400ml can is great value and lasts a long time, making it a reliable product for regular household maintenance. A high-quality, versatile spray that performs exactly as expected, offering smooth lubrication, protection, and long-lasting results.

A friend recommended this to me. I was having issues with the lock on my front door. A couple of sprays of this and everything worked smoothly again. It doesn't seem to cause any issues. The straw nozzle makes it easy to direct the product.

I used this WD-40 Specialist Silicone Spray to lubricate all the door locks and hinges around my home in preparation for the winter weather, and it worked great. The spray goes on smoothly, leaves a clean, non-greasy finish, and immediately stopped squeaks while keeping everything moving freely. The Smart Straw makes it easy to apply accurately, even in awkward spots. It’s reassuring to know it offers all-weather rust protection, and overall it’s an excellent product that does exactly what it’s meant to do.

Good quality sprays

Works well

Cannot go wrong with WD-40 but this silicone formula is excellent for specific uses that requires lubrication as well as water protection, great for rubber seals and great value for money, nice large can

A friend suggested I try this when my patio doors were almost stuck and screeching badly. I sprayed the runners and they started moving smoothly again straight away — no noise, no effort. Since then, I’ve used it in the garage on garden tools and other moving parts (grass cutter, hinges, etc.), and everything feels smoother to use. The can is a good size, and the little straw nozzle makes it easy to get into tight spots. Pros • Fixed my noisy patio doors instantly • Works well on garden tools and hinges • Easy to apply with the straw nozzle • Big can that lasts Cons • Strong smell if spraying indoors Verdict Didn’t expect much, but it really does the job. Handy to keep around for doors, tools, and anything with moving parts. (Photo 1: can with nozzle closed) (Photo 2: nozzle extended with straw tube) (Photo 3: normal spray nozzle shown)

"Who are these losers reviewing WD40 on Amazon", you might ask? So did I! Well! My hanging blinds have been sticking for months and driving me insane. I assumed something was warped or broken, then ChatGPT suggested I try silicone spray... whatever that was... well I saw this WD40, gave it a generous spay, and now it's gliding better than if Torville and Dean birthed a bald eagle. This stuff LUBRICATES. My blinds have never been zippier, I feel like a real man now I have THREE specialist cans of WD-40 in my cupboard. No price is too high for how good I feel about this purchase! The only issue I have is that it doesn't smell quite as good as the original, yet it has a captivating, evocative musk of its own. Highly recommend!
