Good morning ,
I received now an reply from Typhoon regarding cleaning of their drysuits . The answer was quite surprising - but read yourself :
"We use a cleaning solvent in the production of our products to clean the excess adhesive from around the boots / seals we fit. It also removes most types of oil / grease effectively. Please see attached safety data sheet. Due to the nature of the chemical we are unable to ship.
The solvent flashes away from the material extremely quickly and is highly flammable. Because it ‘flashes off’ the solvent does not damage the fabric. A more persistent solvent could cause delamination. When used it must be used sparingly and only dabbed onto the material."
