I purchased a 1980 Hunter 30 this past fall. Am very excited about it and am anxious to get on board and start some projects. It has been bitter cold up here so I have not been able to do much on her yet as she is in a yard about an hour from me.... One of the first project I need to do is a very thorough cleaning, inside and out. She was on the hard for the past 2+ years due to illness with the PO. During that time there was approximately a 3 month period when she had about 8 inches of rain water just sitting in the cabin. Fortunately she was tilted towards the stern so the water was mainly covering the main part of the cabin floor and did not really get up to the wood under the benches. However, I do need to replace the plywood that the stairs are attached to that serves as the removable front for the engine. The big issue is that the teak and holly floor is very dark where the water was covering it. I am considering replacing it completely, but would like to try to clean it first and see if it will be "liveable" at least for this first season that I will be enjoying the boat. Anyone have any suggestions as to the best method for cleaning a cabin floor? Any specific cleaning substances that anyone has found works best?
