Hi Guys,

I don't do a lot of window cleaning, but have been asked if I can help with the staining on this conservatory roof.

It apparently occured after the loft overflow leaked about a month ago.

I did test a small area with a couple of products with reasonable success, however I thought i'd ask the experts....that's you.....if you've ever dealt with a similar problem and what you used to remove it if succesful. Also I wondered what you would suggest for access to the top of the conservatory roofing as I'm not too happy about using crawling boards.

Any help will be much appreciated.

A couple of photo's which I hope will be of help

looks like limescale to me..

mdr it (some people use toilet limescale remover) .. however its a glass reflective roof you will invalidate the warranty using any non manufacturers recommended products, so read the manufactures recommended cleaning products guide.

Ask the custy how old the conny is, did they purchase it? how long is the warranty for? and advise why (as above)

You may need to have a waiver signed regarding the warranty - if they didn;t buy it, then the warranty usually doesn;t pass over with the house sale.

Use a conny roof access ladder - you can rent these for about £25 a day for a hire shop.

I'm sure you're right about it being limescale. The conservatory was already there when they purchased the house.

The customer showed me the manufacturers 'Cleaning Guide' which only said, "Don't use strong Acids, Scourers, Wire Wool or High Strength Cleaning Agents" ....but didn't make any suggestions what TO USE.....very helpful !

Thanks for the tip about the access ladder which I'll checkout.

I hear people on here saying this'll do it or that'll do it. This stuff WILL do it regardless of how long its been there or how thick it is. I had a similiar job to that what you got there about a year ago from a leaking overflow pipe that had been chugging away for a year. I applied this Kilrock stuff and it was sorted within 60 seconds tops. It IS the bees knees.

i use to be a plumber for 5 years, and i have never seen a leaking over flow do that to a con roof,    have you tried hot water and fairy to break it up,

Thanks ..

You'll be there a long time with a kettle, kettles gather limescale like nothing on this earth, if hot water was to sort them out then that would be the place to do it.

[geefree]

soak it with truck cleaner... let it soak until it breaks it down.

scrub with a normal brush... it will shift..

if it doesnt... say sorry i cant get this clean...bye.

 A reply to Daz1977,

I actually thought it was very strange. I expected to see one long mark on the roof and can't quite understand why  or how it covered such a large area.

The customer assures me that's what caused it so I have to take his word for it. It some seem to be some sort of limescale though.

It drips, you can see where it lands, the bare spot and splashes. In the reflection in the glass you can see the overflow pipe is immediately above that bit of the limescale. And in the second picture the offending item is plain as day.

The splashes cause the wide area covered.

[Les]

One last question from me,

are you saying that this Kilrock product is safe to use on reflective glass as it does state not to use Acidic products ?

[Gleaming windows]

What states not to use acidic products?
