First piece of advice is to always, but always, put the cover on the boat when you leave her. (I know you have a nice fitted cover for Topaz.) It is amazing how quickly tubes can fade/abrade in the sun if left uncovered. Cover also keeps the general crap off.
Fresh water wash down after each outing is a must. If no facility at the launch site a jet wash at a garage on the tow home is pretty good.
As for cleaning products .... Inflatable Boat Supplies do some inflatable boat cleaning solvent which is pretty good. (esp. if your tubes have faded!) although fairy liquid does pretty well for the average clean. I've heard of some people using industrial cleaner for washing curtainside artic trailers but would think thats a bit strong mebbe!
A good old sponge is the best thing for tubes. That an a lot of elbow grease!
I noticed on another thread people use Johnsons Baby oil for antifouling, i was thinking this may keep general dirt of the hull when on a wet motorway?????
I use fairy liquid (softer on the hands), Autoglym motorcycle cleaner is good for wiping off grease around the transom/engine area.
I recommend 'gojo' it is an American hand cleaner smells of orange and cleans things great. I have some in the car at all times so you can have a look at the SOC.
