Here's a link to the Lonseal Maintenance Page
The cleaning recommendations vary by flooring product used.
I believe Mainship used the Satin Finsh version which I believe is the middle "Topseal" category.
They recommend a neutral Ph cleaner - bleach doesn't fit that category - mild dish soap does.
Ph of common cleaners
The only cleaning we have had to do on our interior PLasTeak flooring is a Swiffer.
A call or email to the 1877FloorGuy.com

I have the exterios PlasDeck material installed on our aft & side decks and clean w/ Starbright Deck Cleaner and a deck brush or mildly abrasive scotch bright pad if excessively dirty. I have used WoodyWax on exterior to help "seal" the texture and make cleaning much easier.
