Good product but with some confusing information

The are two parts to my review but first let’s get the positives down. Product feels strong and we’ll made and is compatible with the excellent kliclok system. Now let’s get to where the info given is confusing. Products of this nature are always going to need to be cleaned thoroughly after use, so it’s paramount that this is thought of when designing a product like this. In the description it states “This item made from high-quality stainless steel material” and “feel free clean it with household detergent” which seemed great but then confuses me by saying this further down ”SOMETHING IMPORTANT YOU NEED TO KNOW: 
Please do not wash this adapter with strong detergents in case of rusting”. I would expect stainless steel materials to be a lighter silver colour (not dark like this), strongly resist rust and be very easy to clean, just like the 304 stainless steel that there extension bars are made of (which are excellent products btw). So the jury is out until I see how well it responds to being cleaned and if it ends up rusting in the places I can’t easily dry i.e inside the spring.
