Cleaning Interior

Tim,
I thought that the clearcoat mention was a slip. I guess I stand corrected. Do they apply a clearcoat to all vinyl or is it only applied to marine vinyl?

Anyway, I see your point, and if I had a new boat with perfect vinyl I would not use anything that was not recommended by the manufacturer.
But, my boat was 15 years old with the original interior and was covered with dirt, stains, and a fair amount of mold. When I started to clean it up, I started out with Murphy's, then went on to dish soap but it was not getting it clean and white. Then I tried the Starbrite mold and mildew remover (which to me seems even more of a strong chemical than the scrubbing bubbles), and although it did work pretty well getting out the mildew stains, it did not get out the deep down dirt and make it look white. So, after reading (I think on CCF) I went ahead and tried the scrubbing bubbles and was very happy with the results.
Now that I have the vinyl looking almost like new, I keep it clean with water and a small amount Murphy's followed with a clean water rinse and a generous application of 303.

I was told by Christine's only use a mild dish soap followed by 303

we always soak the boat when we come back since were in salt water. guess i learned something today don't soak the carpet

Best stuff I've found to clean the interior is Scrubbing Bubbles bathroom cleaner, the foam stuff in the green aerosol can. Spray it on and scrub it with stiff brush. It softens the vinyl and makes it nice and white. follow up with a water rinse and finish with 303 Aerospace Protectant. The Scrubbing Bubbles is the best thing I've found to get the interior really clean and soft

If you have some mildew, Starbrite mildew stain remover works good with the stiff brush.

Is it OK to hose down the interior to give it a good cleaning and then let the bilge pumps do their thing, or even remove the drain plug from under the motor?
