Who’s got the best clean-up tips??

My Nautiques had a long hard Winter's nap and it's time to spiff her up for the summer!
Chalky hull & Mildewed interior are my worst problems.
Need some cleaning tips - over the counter or a homebrew - Let's hear what has worked best for everyone.
(I've got a great homebrew for cleaning the teak platform. I'll post it once I find the recipe!)

My boat has a white textured interior. Using interior cleaner on the surface always worked nicely, but the recessed texture of the interior always retained dirt and looked dingy.

Last year I discovered by accident that if I use go-joe orange hand cleaner with Pumice (pardon my spelling) in it that the hand cleaner will clean the recessed areas of the interior much like it does on the lines of your hands.

I found the following process to work:

1) Wipe the surface of the seat I am about to clean with warm water on a rag.

2) Squirt a generous ball of the hand cleaner into your palm and rub the cleaner gently onto an area of the interior to be cleaned. (don't rub too fast, too hard, or too long as the pumice is abrasive and will cause an abrasion on the seat).

3) Follow with a warm water rinse using a rag.

4) Apply STP Son Of A Gun cleaner / protectant on the surfaces.

After completing the clean up they looked like new, the results were amazing, this process removed dirt and shoe marks that I have been scrubbing at for a couple of years.

I now keep a small bottle of go-joe and STP in the boat and anytime some one leaves a mark from a shoe that was not removed or due to dirty fingers....this process cleans it up very quickly.

Use caution when rubbing the hand cleaner on to the interior. If your rubbing motion is to long or too hard you could cause an abrasion on the surface of your interior as the pumice is abrasive.

Last weekend I hit the Nautique, interior & exterior, with 50/50 white vinigar & water. Mixed it in a spray bottle, sprayed and scrubbed with the rough side of one of those two-sided sponges. Did a GREAT job!
Most (not all) mildew & dirt came out of upholstery. Took scum line (left over from last summer) off the hull.
This weekend I'm going to go over upholstry one more time & then cover with 303. The hull will get wiped with Penatrol, then NuFinish polish. Clean carpet. Put everything back together and fire her up!
I may even get her wet this summer!

have a cover made that covers the color gelcoat on the sides of your boat and your worries are over, no more fade or oxidation. i wet sanded my royal blue as it was grey 3 years ago. then buffed it out with some professional myguires stuff that took out 1000 swirl marks. i think it was called diamond cut or something like that. then hit it with swirl remoover then waxed it. it never faded back and still looks great 3 years later. the 50$ orbital buffer from sears is a toy and only good for taking wax on and off. to use the stuff i did you need a variable speed buffer in the 250-300$$ range. then some good wool pads and then some common sense as you can take the color clean off as its only so many thousand's thick.

down in houston its just now getting tollerable to even go outside. time to start riding.
for the hull i use hull cleaner by star bright it turns a yellow hull bright white in a hurry.
interior i have no hints, but looking.
