Silicone Lubricant Spray, Smart Straw, All-Weather, 400ml

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.

Easy to use, works well, very pleased

I've used the standard WD40 spray for many applications over the years. I'd never tried the Silicon spray so I thought I would try it out. I have to say that I am impressed by the results. I bought it chiefly for freeing up PVC window and door hinges and locks. It has worked perfectly on all points. I even sprayed the lock on the PVC back door which gets used multiple times throughout the day and has been a continual source of irritation with the locking mechanism sticking and taking force to close and lock. I'd tried various products to free up the locking system but nothing worked particularly well and never lasted. I gave the key holes, handles and locking mechanism a good basting with this Silicon spray and wow it worked first time! The whole mechanism works smoothly and perfectly for the first time in years. I had contemplated getting a complete new locking mechanism. Thanks to £9.17 can of WD40 Silicon spray I've saved myself a lot of money and hassle. I've also successfully used the spray to help drive out moister and protect a range of electrical fittings including a connector on an outside waste water pump fitting that had been shorting out. I sprayed our metal curtain poles to ease the flow of metal curtain rings over the poles. The curtains have been sticking and snagging for a couple of years. I'd tried freeing things up by spraying the poles with various furniture polish sprays. These didn't work well and failed after a couple of weeks. I sprayed the silicon onto a cloth and wiped the curtain poles over with the spray. The difference was immediate and lasting with the curtains rings now flowing freely and easily along each pole. I can actually close and open each curtain with one finger whereas before it took some effort even with two hands! This spray has worked for every job I've used it on. In my experience and opinion this is an excellent product that can be used for wide range of applications. Highly recommended and I will definitely be buying again!

Brilliant product! bought to mainly use under my treadmill belt as had a very thin like straw attachment nozzle to spray in small spaces only need a very little amount goes along way also I have used throughout the house on other things it’s a very good product doesnt give off a massive smell either and a big size bottle for the price

Did efficiently what i bought it for, excellent product.

I've had my MX5 for 7 months now and ever since I've had it, the seatbelt hasn't retracted. Some times it'll go slow, other times I'll not move an inch. It was cleaned, rails cleaned, guide replaced, no difference. I saw a forum post about using silicone spray to solve the issue, I picked up some of this. Cleaned the belt before with an APC then let it dry. Blasted this all over the belt and the guide, pulled it in and out a few times and fingers crossed, it's solved the issue. It's not sticky or greasy, can't really feel it once it's dried. Magic!

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.

Very quick delivery, excellent product, good value.
