So I got this gt convertible, with a white top and white leather seats. When I was cleaning, ans crubbing the hell out of the top and seats, I noticed a few of those stains just don't want to come out. I tried the normal soap that the self service car wash spits out, preston interior cleaner, with the plastic scrubber, and armoral leather care and cleaner. Nothing happened. So how far should I go with this? Bleach? I know it's corosive, but then again, cheap t-shirts dont desintegrate when washed in bleach. Also, my skin tends to hold up well if bleach get's on it. Leather is cow skin, and the top is vinyl. But there's the waterproofing on the top to consider. I don't know. The stains are black. Probably grease or oil. Nothing too major, but still noticable. I know how expensive it is to replace a top, so I'm not even gonna consider that yet. As far as the seats go, I bet it's even more expensive. Who else has had luck getting stains out WITHOUT burning a whole through the material?
