Is it safe to lubricate threadmill belt?

farmer jeff

sketchy applicator

Needed a new can of spray silicone to general non greasy lubrication at home and work. The wide angle, spout down, feature, at least on the can I have, does not work. Comes out in a powerful direct stream. This makes it next to impossible to accurately coat anything but a point surface. If you need a wide angle applicator, get the other stuff.

product made my windows squeaky

I cleaned the window tracks with dry cloth, then wiped with moist paper towel, let it dry and sprayed the WD 40 Specialt Silicon based lubricant. While my windows now slide more easily, they make an awful squeaky sound, which didn’t happen before. How do I fix this?!? Please help.


Greatest spray ever

The best silicone spray I have ever bought and used


Water Resistant Silicone will it ever dry ???

Bought last night.. I was drawn to the product as it said " QUICK-DRYING " on the back " DRIES IN SECONDS " So I shake the can for over a minute spray it on, wait 5 minutes... still not dry. 30 minutes still not dry, 1 hour still not dry !! So I go to sleep, work.. after 24 hours still not dry. Im not sure what is going on with this stuff but I must have gotten ripped off cause this stuff does not dry. As I am writing this i still have this stuff all over and it caused spots on my parts. Not happy.

Thank you for reaching out. The speed at which the product dries is impacted by the environment. Cold or warm, moist environments require a longer drying time. Regarding the spots, if the product was sprayed on a surface with a greasy or oily coating, the silicone may bead and leave what looks like spots. If this is the case, clean the parts thoroughly and dry well, then lubricate with the silicone spray. Please let us know if you have any other questions.

Spray problem

I purchased the WD40 specialist water resistant silicone lubricant today and the spray straw doesnt work. The o-ring fell out of the can when moving the straw to its spray position. I am assuming the can top is defective as it doesn’t spray normally either. Disappointed.

Good stuff...

Ive been buying WD 40 for years now Great stuff....Used it on chains to ball bearings to getting old stickers off your car bumper it really has many uses and will always ues WD 40....


Works great on locks and hinges

Used it on locks and hinges. Everything works. It have been like 5 months now and nothing is stuck or sticky. Much more better than the old oil spray. Also good on windows if you have a hard to open window. I recommend try using it. Spray it on the left and right side. Pull the window up and down so it will be well lubricant.
