I went to my local Dive Club on Saturday and used a small amount of Spray 9 on the tubes, as you can see the results are amazing.
With very little effort the tubes came up like new, in the past when I have used it I certainly was not knackered or up to my elbows in soap suds!!!!!!!
Dan (ex Top Banana fame) introduced me to it, and those people who know Dan and Top Banana will remember how good it looked.
Once cleaned with Spray 9 I used Once Over, I just wiped it on and this gives it UV protection.
