I didn't think this topic would be controversial.
There are many things car enthusiasts do re detailing that most car owners never do. Or they pay detailers do do.
I searched the forum & found nothing on this so, I posted.
As stated, I have never cleaned any car carpet, just shake them out occasionally & maybe vacuum if a lot of debris.
I just cleaned & treated my leather interior in 2 cars. I just helped a relative buy a used car which has cloth seats & had been offering suggestions; ck CTP, Ck tread depth, make a schedule so they know when maintenance items s/b done, etc. I suggested that they treat their seats with Scotchgard. (After seeing some videos on this & discovering Scotchgard makes a product specifically for autos.) I looked for a video to send them on How to. I was surprised that most of these videos were for using Scotchgard on Auto Carpeted Floor mats! I had never considered doing that. So, I thought why not do that to my carpets one time (& never again) My Macan carpets would vacuum clean (being < 2 yrs. old)
I do always switch to my Porsche all weather mats when going hiking so, don't get mud & large amounts of dirt on the carpet.
Then I thought that my other car is 17 years old & the carpet is dirty so, I should clean it b4 sealing in the dirt/stains with Scotchgard. And why not a quick clean for the Macan mats b4 sealing with Scotchgard? I assumed (apparently incorrectly) that many on the Macan detailing forum would have been doing this type of thing & there were dos & don’ts re which products to use.
My 1st thought was to use car soap & a scrub brush & then let mat dry & then spray with Scotchgard. But, what if others warned against that for some reason? Maybe car soap would damage the carpeted mats?
Hence, my post.
