Hi,had a comment today that my pure water had "dulled" or removed the surface off a window painted with Sadolin wood stain,,,,do you think that is possilbe ? The customer has just last week had them repainted,so I am going to blade 2 windows and wfp the rest to make a comparison,,clever eh?

De-ionised water turns light coloured solid oak doors dark and weathered looking

Hot de-ionised water will draw the wood stain out of some natural wooden frames that are not painted.

I used to do some wood-stained doors 'trad'

Even with ordinary mains water and no detergent my wiping cloth still turned brown.

Try it with plain water and if the stain still comes off, show them.

I would imagine most of the modern stains are waterbased now? So probably anything will tend to rub the surface off a little?

To do a proper comparison the windows you blade would need to get approx the same amount of sunlight as the wfp ones as sunlight is damaging to paint/stain.
IMO pure water has a detrimental effect on wooden surfaces generally and is my biggest concern using wfp.

Agree with dd.
We don't take on customers with wood stained windows any more. WFP leaves marks on the stained surface and makes everything deteriorate more rapidly.
My advice is leave well alone, just go for plastic frames or you will be building up future trouble with the customer.

I clean two large houses  both with wood framed windows sadolined -- one very recently re sadolined -- the frames 6 of them are in the shade next to a wood therefore prone to cobwebs and green algae. I give the complete frame and glass a clean every time. the customer is delighted. No problem what so ever with stain or damage to finish on frames. It must be the way I do them. (-:
Keep well John.
