just want to know what is working. I currently use Grease Lightning.

Simple green

then I use a protectant like armor all to keep the sun from hurtin it too much

magic eraser....works like magic

magic eraser for exterior vinyl only. Do Not Use inside cabin on leather.

Becareful using products like Greased Lightning, Castrol Super clean, Ect. They will remove the oils from the vinyl and cause premature aging, if used frequently. Greased Lightning has a marine version of its cleaner that isnt so harsh. What ever you use, put a good protectant over it to put oils back, and protect it from UV rays, that are as harsh as the cleaners.

It's amazing at how well it works with just water.

Use it with a little bit of dawn dish soap and it works even better.

Magic Eraser made my seats look 10 years newer.

thats what we do for both inside and outside. the eraser works great to cleaning the transom

Tuff Stuff to clean then some sort of vinyl conditioner. Works great. I have used Tuff Stuff for over 15 years on my cars and boats and have never had a problem with drying,aging or yellowing the vinyl whatsoever.
