I bought an aluminium tube a couple of years ago from B&Q and extended the reach on the one I've got, had it for three years, came from Wilkinsons.
Could do with another 25l of tfr. I've had the same barrel of fleetclean for the last three years and have not been that impressed to be honest. Might try a higher foaming one next. Any suggestions?
Some of the Lidl and Aldi stuff is pretty good to be honest. Used to buy cycling kit from there, Mrs has their running kit. Cheap as chips and lasts pretty good, third of the price of anything else.
