If you have a real auto interior issue these are THE folks to use. We had a used motor oil spill in the back of a small SUV and it smell awful. Oil had run under the carpet and seats and I thought there is no way we are ever going to get this cleaned up. We called Ralph on a Friday and he was out the next Monday to clean the car up. He removed carpet, trim and seats and worked his rear-end off to get the car cleaned up and the smell eliminated. He put everything back together and detailed the interior. When it was all finished the smell was definitely gone but I frankly was still worried that it might come back. I don't know why I was worried but I was. The last thing he did before he left was to treat the car with a chlorine treatment that required us to keep the car closed up for about 24 hours. When we opened the car up and quickly aired the chlorine all smells were gone. And the best new.... the smell has never returned. I can't recommend Ralph enough to remediate tough auto interior issues. He's the man!
