How much is down to how and what you are removing - algae doesn’t need much where as black spot needs quite a strong mix - generally we use a 10 ltr pump sprayer mixed at 3 to 1 so a litre of hypo and this is enough to cover a drive 3 x 8 meters

Surfactant- see the other thread splash has a photo of the best 2 - see instructions for mixing

Decking - cheap cedar and pine will come up nice with hypo but not the correct stuff as over years it will break down the wood fibres

Other woods may not even be suitable for p/w as you will damage them

A good cleaner is net-rol

Never even gave that a thought. After a year on the forum I had a better van system than all of them put together. I was running a hot water system in the summer with electric reels. It's all beginning to make sense now. Anyway, I have all the contacts for equipment and don't need any help now so better focusing on my business. I do like to help folk so that's why I liked the forum but it does take up some time so I'm better away from it.

{It’s certainly possible for those that are willing to do whatever it takes, work like a machine for years, reinvest every penny, cope with stress levels that could kill most people, and ignore naysayers and haters.}

I really like the above post because I was on the other forum and worked 6 to 7 days a week and invested every penny back into the cleaning business. Luckily I had the fire service pension and lump sum to begin with and buy the most efficient system to make my work as simple as possible. After 5 years it all began to pay off and I was making £200 a day. Then I slowly creped up to £300 a day and the naysayers didn't like it one bit so they barred me from the other forum. Every time I left, the forum slowly died and they asked me to come back and it picked up again. They have asked me to come back but no point, still the same naysayers that want folk to fail. I can make a great living staying under the Vat level so I have no intention to add a van nor employ anyone. I do PW, Roof Spraying, PVC Spraying, Window Cleaning and painting for folk I know well so I only have 100 odd windy customers.

Fewe questions so i`ll just bundle them here

I am replacing my existing tank and would like to find a home for it.
It is a typical 500 upright tank with a standard tank frame.
I live in King's Lynn,  anyone who's interested in collecting it.
I am taking it out of my van on Sunday 5th.

NOW TAKEN.
