I used a brush today when using my vinyl cleaner. Iíve never done this. In the past itís always been terry cloth towel + spray + wipe = done.

I can see where using a brush to agitate the cleaner would be effective on a dirty piece.
But how effective is it on interior thatís already clean.

Is using it more psychological the anything?

And a quick question about the foaming when agitating.
I noticed when agitating the cleaner on the piece I was clean sometimes it would suds up. Other times it would not? Iíd use the same amount of product but 1 bolster of the seat would suds up and the other bolster wouldnt?

Does it only suds/foam up when thereís dirt?

*** I did this on my interior vinyl and leather.
