How do you wash your boat?

[pvb]

All fine ... but, done afloat, run off, needs some consideration of toxicity, environmental issues.

The typical dilution means that any harmful effects are minute.

A good thrash unwind in a F5 to 6 does a pretty good job.

I apply Autoglym super resin polish to the GRP twice a year, at haul-out and at launch. In between I wash her down with a hose, a soft brush and car brand wash and wax. I also apply patio magic to the teak deck twice a year. I’m happy to clean while on my hands and knees as it gives me the opportunity to look over her at very close quarters.

That is exactly what i do & I use a wash leather on the smooth areas of GRP
I have found a soft broom with a fairly small head does a better job of the non slip deck than the typical stiff brushes sold in chandlers.
I often do the deck with a squirt of the cheapest washing liquid & a scrub with the soft broom.
Sailing on the east coast in heavy weather sometimes leaves the deck covered in a fine layer of muddy film so that does not work. Although even in rough weather my boat is a very dry one & does not actually take that much over the deck. Unlike my Stella which was more like a submarine.
