This video shows how to properly clean and dry a 3.8-metre Itiwit 2-3 seater, one of the most popular IKs of 2020 – or at least one which remained available when stock of so many others ran out.
It also shows the inner bladders and how they fit: something that’s rarely described on vendors’ websites.

Like so much Decathlon gear, their shell & bladder (S&B) IKs are a bargain. This orange Itiwit cost just £300, but the cleaning and drying process takes a while and realistically, is something best done over a couple of hours back home, if you have the space.
Quite rightly, after a sea paddle the owner was concerned about sand and other grit getting into the nooks and crannies around the floor, and even inside the sleeves which house the relatively fragile bladder ‘inner tubes’.

As it happens, the sidetube and removable floor sleeves plus their respective bladders (above) were merely wet inside. As on all IKs, the grit mostly settled down in the gutters inside where the floor joins the sides. This is why, with full drop-stitch (FDS), drop-stitch floor (DSF), or S&B IKs like this Itiwit, a removable floor makes proper rinsing, cleaning and drying so much easier.

Tubeless IKs like vinyl ultra-cheapies, most PVC Sea Eagles and IKs made from synthetic rubber, like the old Gumotex Sunny (below) and packrafts, come to that, merely need seats unclipped before a freshwater hosing and a wipe down. A river paddle on a warm day won’t even require a rinse: just wipe the boat dry and roll up till next time.
