Having tried loads of expensive snake oils in the past and recently recommended Fairy Power Spray on this forum against current popular TFR I thought I best run a test for my peace of mind........
I bought some TFR concentrate from machine mart.
instructions suggested 600:1
which was a waste of time but 50% in a spray gun and it worked
Used a sponge , lot of rubbing , left 1/2 hour , sponged and rinsed off.
Result clean but rope burns and some black scuffs remained.
I used the fairy power spray on the scuffs and rope burns, trigger spray and is much thicker than TFR, its more of a gel, left it 1/2 hour (note no scrubbing) wiped the rope burn and scuffs off and rinsed.
Snakeoils from the chandler work marginally better than a fresh water hose.
TFR is good but only 60% as effective as Fairy Power spray.
Only one left water beading on the surface and a shine without a buff,
Fair power spray clear outstanding winner, it is more expensive than TFR but lot less effort needed.
Worst snake oil came from Zodiac, bit like a T Cut cream, took all day to do a boat, 2 x bottles of power spray will do a boat in an hour, most of which is drinking beer while waiting for it to work.
After the whole boat was cleaned with TFR , and I gave the isolated rope burns a fairy treatment I decided to do one section with Fairy power spray as I wasnt 100% happy with TFR, navy is Fairy Power spray, grey TFR x 2
