How Do You Clean Your Polytunnel?

[MarkPelican]

Warm soapy water and a soft sweeping brush on a rainy day. That way it gets washed straight off.

That was my thinking Mark but thought the vinegar may help break the muck down.

I suppose it depends how thick the muck is. But I've found that soapy water and a soft sweeping brush seems to work The problem is reaching far enough.

Iv'e used this on my patio, fence and drive with good effect- just spray on and leave. I have to be honest, I've not put it on the polytunnel yet but I don't see that it would degrade the plastic:

My tunnel has been up for a few years now and last year was the first year it started to green both on the inside and out- I wiped both sides down without any product, just fresh water and a soft long handled brush, it looked ok but it's gone really green again over the winter so I think it needs more than a water treatment this time round so I'm going to give mine a spray.

Just thought to add...In one the polytunnel books- Polytunnel handbook maybe?- they suggest tying two lengths of string/rope to the diagonal corners of an old sheet and with the help of another see saw it along the length.

Yes, I've seen that but my drawback is that the polythene has debris netting on top of it which cannot be removed..

I guess it's going to be a careful brush job then, that's what I thought was good about the patio product above - spray on and walk away. I was wondering about a mild bleach solution but with the additives you could discolour the shade netting, could that happen with vinegar?
