## Description

From the manufacturer

Review: Excellent silicone spray that protects, lubricates, and restores smooth movement - 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.
Review: Brilliant product - 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.
