Why is wd40 so expensive these days?

A large can of wd40 seems to cost like a bomb you'd think it would be like $3 for a large can (not a nozzle tube can) but where I'm from its just insane prices to the point the college I went to to learn automotive were mixing their own form of wd40 using recycled car oil and something else & telling us it's wd40 which probs saved them like 13k a year in costs.. is there like a global share market for wd40 or something which is somehow trying to pay millions of people in shares because it's seeming like it's got liquid gold in it..


WD-40 Multi-Use Product - Multi-Purpose Lubricant with Smart Straw Spray. 11 oz. (12 Pack) by WD-40 $49.88 ($4.16 /can) https://www.amazon.com/WD-40-Multi-Use-Product-Multi-Purpose-Lubricant/dp/B00JIHTCR8/ Recycled oil is not the same thing.


Same reason HC is soooo expensive. .


If you want to make it yourself, you would need to run a sample to use a GCMS. And, if you then find out the ingredients, don't expect to pay the same price for volume at Home Depot that the WD-40 manufacturer gets when it buys the ingredients by a tanker car.


Because a lot of R&D went into its development. Water displacement 40 is made to a very specific formula and not just made up with mixing petrol with old engine ils etc etc
