It say's that because one doesn't want to clog those tiny holes in the leather, so you should clean your Perforated leather with what the manufacturer said to use on it using the proper solvent recommend by them. Using the wrong leather cleaner can ruin the finish and cause those tiny perforations in the seats to clog. This will affect their appearance, breatability and comfort to you. I recommend to go the simply why in cleaning them, I have use Woolite and water mixed about 6-8 parts water to 1 part of Woolite to clean the leather. Always wipe it off lightly using a mircofiber dampened towel ( very Lightly ). Then wipe off the surface again with a dry microfiber towel to allow the leather to dry properly. From there you can use Leather Masters Leather cream or Turtle Wax leather conditioner in a spray bottle that works very well for me.
