How to use M40 to clean rubber?

[OCDer]

I'm using M40 for the first time. I'm mainly hoping it will clean up the exterior rubber seals around my windows. I wasn't able to get my hands on #39.

How do I use it? I know that I can use an applicator or MF towel to wipe it on the desired surface. But if I want to use it for its cleansing ability, do I use the towel to wipe back and forth on the dirty rubber? Should I use a dirty MF towel or a clean one? Or will a terry towel or brush be even more desirable?

Thanks.

I usually just go over the seals once or twice. M40 cleans them well enough that way.

I use a 'dirty' meaning used towel that's been washed; same one I use for the wheels. Sometimes an old thick T-shirt works well too & I can throw that away if the rubber is real dirty. I always roll down the windows too to save the time of cleaning the liquid off them.

Thanks for the advice. I used a dirty towel to wipe my exterior rubbers, and a lot of dirt and grime were rubbed off, but there are still marks on the rubbers that I can't seem to get rid of, no matter how hard I'm scrubbing. Is M39 or a strong APC (D101 @ 10:1 hasn't helped) needed, or are these stains (or whatever they are) beyond repair? Thanks again!

Try some diluted APC with a brush, like a toothbrush. If that doesn't take them out then I'd let them go & use something like Solution Finish which will restore the black and probably cover them up pretty well. Solution Finish is pricey but a little goes a very long way and it's durability is terrific.
