For example upvc frames have added as an additive during manufacture tio2 titanium dioxide which helps to protect them against damage from sun/weather, because of this some upvc window and door manufacturers will offer a 25 year guarantee on their oem products. these same manufacturers will also recommend that harsh and aggressive cleaning chemicals should not be used when cleaning these type surfaces. upvc when new is bright shiny and has a lovely sheen to it, i damaged a huge amount of these surfaces myself over many years until i realized how corrosive the ingredients were in the cleaning chemicals i was using. my point being its safer all round to ask your supplier for cleaning chemicals which are non-caustic non-corrosive and safe for use on pvc/upvc surfaces and that won't affect their shine. tio2 is a whitening agent used in many cosmetics/toothpastes etc,yes its used in pvcu manufacturing only because we preferer whiter than white in the uk,there are around 47 shades of pvc window extrusions across the european market-for instance the germans and belgians prefer a more creamy white to us brits-hence the more ti02 added to the extrusions produced in the uk,rehau-a german product produced in wales for us brits is more white than say kommerling which is slightly blueish in tint,compare that to spectus which is british and they are shades apart.ti02 is not a protective agent it is a whitening compound added to the product to give the required shade of white to which they require for a given hemisphere, Hi Kevin, Yes tio2 is also used in many products for its whitening properties, manufacturers of upvc windows and doors also add tio2 during production because its known to provide good UV protection by reflecting and/or scattering most of the suns UV-rays through its high refractive index. Again its the use of caustic and corrosive ingredients used to make harsh and aggressive cleaning chemicals cause most damage to upvc surfaces, i am not saying that Vision will cause any damage to upvc surfaces as i have never seen the sds so don't know what it's derived from but from the high dilution rates the lads recommend i could not see it having any detrimental effect on upvc, but i think you probably know the types of caustic and corrosive cleaning chemicals which do cause detrimental damage to upvc frames and doors.

dull I may be at least I don't have my head up my back side its only window cleaning not rocket science.get a life
as I have said before its only window cleaning I cant see the point of faffing a bout .its a domestic job that the custy cant do or wont do themselves I just cant get my head round something that is so simple is made out to require all the fuss .some people are in the wrong job. but that's just the way I see it .keep it simple.imo
this was turning in to a which hunt ;Dsome times that's what happens when you express an opinion.
I honestly thought Dave Willis photo would put this nonsense to bed, Guys its simple take a look at his photo and if your not getting the same or better results then use an additive of your choice or continue on as you are until your customers complain or start going elsewhere its up to you.If you are getting the same results then continue using pure and don't try to fix something that isn't broken.
