hi
I would very much welcome any suggestion if there is any?
I've been asked to do a builder clean .
the state of the windows is not too bad
The thing is I'm a wfp user and wonder if there is a way to get rid of a few cement  marks on the glass?
many thanks for any suggestions

Best to do builders cleans the old school way up close and personal so can do the job properly instead of trying to wave a stick about.

We do alot of builders cleans and to do them properly it has to be the traditional way, we use Titan products to remove stickers,cement marks etc, they do a chemical called Cement  Off and a solvent cleaner called Oil Flo 141,both very good,
You  can purchase them online from various window cleaning shops.

Thanks all for the reply.
I somehow had that crazy idea about fitting a scraper at the end of  a stick  to get rid of cement marks  but it would probably be too much  hassle.
yes  the only way to do it properly is going up the ladder

would it be worth trying :soaking a cloth with that product  put it on top of the pole, rub the cement mark with it and then brush it and rinse rinse rinse with the wfp?
Any chance of it working?

[Soupy]

No. Go up a ladder and soak it with the spray. Depending on the amount of cement on there, and the length of time since it set, it turns to mush and can (theoretically) be cleaned off with wfp after about 10 - 20 mins.

If there is more than splatter, and if it's been left for too long, you'll still need a scraper.

We promote a product called cement and mortar remover, comes in a 1ltr concentrate  bottle which you dilute 5-1 into a trigger spray bottle from 1ltr concentrate it will make 7 x 750ml ready to use spray bottles working out at £3 per 750ml spray bottle including postage. it contains an organic acid and is far safer than using products containing hydrochloric acid, just spray it on the surface and allow 10 minutes dwell time and you can just rinse off the concrete or mortar stains, for very heavy stains you may need to give it a second application, if you ever use a scraper on glass always get a waiver signed off from the contractor or else it could cost you dearly, if you would like more info send me an email to info@jskcleaning.ie  Tadgh

Scraper or not; get a waiver signed.

Many thanks for your help
I will give builders clean a miss as I'm only using the pole.
I' take note about beeing extra careful  using a scraper while trying to remove cement marks.
I've always done it that way so far and never scratched any windows ( maybe I've just been lucky!)

[Soupy]

It's nothing to do with luck.

Used properly a blade won't scratch glass. Normally the issue is with cheaply manufactured windows.

Agree and is getting very common so if you use a scraper always best to get the building owner to sign a waiver first to cover your own arse. Not too mention have the proper insurance cover too.

On the gleaming insurance site http://www.gleaminginsurance.co.uk/ there is a prime example of a cleaner damaging glass with a scraper. Here is what happened....



Type of claim: Damage to Property Worked On (Window Cleaner)
 Outcome: Claim Paid
 
A window cleaning customer of GLEAMING INSURANCE contacted us to advise that he had recently completed a builders clean of a new commercial development and that his customer had now alleged that 62 of the window were showing evidence of minor scratches. This damage was holding up the opening of the new development and urgent attention was needed.

Our client was worried and didn’t know what to do, he was concerned at the possible cost of rectifying the problem and he was also concerned that his customer would hold back monies due to him for other works carried out.

A normal liability policy from many other insurers would have an endorsement with an exclusion for “damage to property worked upon” meaning that scratching or breaking glass would not be covered, but this is core cover on our policy and something that sets our cover apart, so we were firstly able to reassure him that this kind of damage was covered with GLEAMING INSURANCE.

We then immediately involved our insurers and their liability claims team and we were able to get a specialist repairer and loss adjuster to speak with the customer and his client and arrange prompt repairs to rectify matters. The insurers were able to ascertain that the scratches were not deep enough to warrant replacement, but that they could be repaired and polished out to exactly the same level as a brand new pane of glass – most other insurers would have simply paid for a replacement.

Our client not only kept his customer happy, but received his monies on time and more importantly for the future didn’t have an over-inflated claim on his record for years to come.
