So I was doing an interior detail on my friends Volvo s60r and I must say 1z deep plastic cleaner worked amazing on the leather seats. So I was using it on the dash and door panels and I noticed a weird look, looks like some type of coating was peeling off. I had no issues any where else, just the rear door panels. My process was spay on the panel and use a hogs hair brush and agitate it for 30 seconds then wipe off. Anybody have any info one what could be happening ?
Here is how great 1z deep plastic cleaner worked on the leather seats.
