Re: Deck Soap, low cost
Not long ago, related to the Gulf Horizon spill, we tested a large number of cleaners, including Palmolive, Dawn, and Simple Green, and we concluded that claims of low toxicity and biodegradablity mean nothing at all. For the record, the above 3 products did terribly in toxicity testing. If wax is not a concern, simple alkaline cleaners did best; in simple language, as soon as they are diluted to neutral pH they become ineffective and the wastes fall out.
* Toxicity. Products a person can drink can be lethal to fish, the surfactants destroying gill tissue. A very different metabolism.
* Toxicity. A great portion of the toxicity comes from the cleaner making toxic materials more bio-available; cleaners often increase the toxicity by suspending materials that would otherwise settle.
* Biodegradability. Under what conditions? Almost everything degrades under some conditions, and most things don't degrade under others. Are the byproducts of break down dangerous? The phrase is meaningless in advertising.
If wax is a concern, RichH made the most sense. Personally, I would rather sail than wax.
