You should dry clean your suit everytime your going to use it , or if you rarely use it, dry clean it every six months.
First of all, you need a boat, preferably without any holes! You need to dress appropriately, i.e wet suit or possibly even a dry suit. Over that you'll need overalls to protect both your wet suit and yourself from the wind .Then you'll need to rig your boat... happy sailing.
The best way to clean a suit is to have it professionally dry-cleaned.

If your wearing a suit, sort of. If not, than obviously no.
The best thing to do is have it dry cleaned.
A dry suit provides better insulation by trapping a layer of air between the suit and the skin, which slows down heat loss from the body. In contrast, a wetsuit allows water to flow in and out, which can lead to faster heat loss from the body, making it take longer to feel warm.
If you are asking about a business suit take it to the dry cleaners.
You can practice in colder water. You an also wear a wet suit or dry suit.
Have it dry-cleaned.
They have their place if you are diving in a dry suit for an extended time. If you are diving in a wet suit they would not be needed for obvious reasons. Scuba diving can dehydrate you from breathing the dry air in the scuba cylinders, so hydration is a must.
NO!!!!! Dry clean only if you want to perserve the quality of the suit. I would also hope that whatever color your suit is...you have another suit of that color so you aren't constantly taking it into the cleaners which over time wears on the material.
