Very good cleaner!
I mainly use it for cleaning my motorcycle and bicycle, either dry with a cloth or before washing.
I used to use paraffin oil but it didn't clean as well and left marks.
I prefer this one, using it with caution.
For the chain, I have bought a different cleaner.

Yes, it does clean well wherever it is sprayed BUT:
after a few sprays, it starts to leak at the base of the plastic cap (at the point I am showing you in the attachment), resulting in a mess all over the place and it also falls on my clothes.
No matter how hard I tried, I couldn't stop the leakage. Apart from that, it has a special nozzle, etc. It's better with the classic red "button" that these products used to have.
I won't buy it again because I can't collect whatever is leaking. I want to spray in specific areas, not like watering the lawn where it goes wherever it wants.

I was impressed with my old outboard motor

I was swayed by the many positive reviews. The product does not remove rust. There are infinitely better products out there. Money wasted!

I bought it because my wife asked for it for the oven. She also spoke with the WD40 company first for confirmation. They told her that it is also suitable for the oven (cleaning from grease, etc.). She used it. The smell from the oven lasted for days. Every time she opened it, it was suffocating. It does the job it claims, but don't use it in the oven. You will want to throw it away afterwards!

It does its job well. However, it requires a relatively large amount each time to easily clean old oil/dirt, and it finishes relatively easily despite the fact that the degreaser packaging is larger than the other wd-40 products. So it is relatively expensive for its duration but worth it.

I bought it to remove all the old oil/grease from the bicycle chain. With a good spray and rubbing, the chain became like when I took it out of its packaging. I put fresh oil again, and it became buttery like in the beginning. Very good product.

For the bike chain degreaser that I bought, it's OK. It takes 3-4 minutes to let it work but afterwards you can see the dirt and grease running on the ground with it. Does the job!
