Right this might sound like a really stupid question but in sunlight from a certain angle I sometimes see smears. I use fairy and change my rubber reguarly (that sounds rude) and seem to notice in this weather. I do not think their is anything wrong with my technique and change my water regulary.
one of my customers said to me today that I left a few smears on a few of her windows and I ended up paranoid. Is it just one of them things that the customer does not notice?
It sounds as though you`re not breaking down the grease/dirt etc before blading off. The washing of the window with the applicator is as important as squeegee technique.
And this is harder in strong sunlight. Dirt can seem baked on and the glass can get very hot. So when you apply your solution with the T-mop it can dry out quickly.
Keed your applicator wet, soak/ scrub the window and blade off in sections before it dries off.
You could also cool the glass first with a spray bottle or damp cloth.
I do try and keep it as wet as possible. And on patio doors and big windows I try and do it in sections. Going to try GG3 and will just have to accept that I will be a bit slower. I actually prefer working in overcast conditions as It is more comfortable.
What size squeegee do you use? I find a 10" good on houses, especially in hot conditions. And as Stu-Mac says, try to get your squeegee horizontal or it in the T position, you will get less kicks.
GG3 can be difficult to use in hot weather if you`re used to Fairy.
You should be ok if you wet the window enough and scrub well. A light pass with a soaking applicator may not be enough, let it soak the glass, scrub and try circular motions- that`s good for getting suds with low foaming solutions.
Also ensure you get into the corners of the window, they are often the dirtiest part. And you could try holding the T-mop by the sleeve (not the handle), this can give you more accuracy and pressure to scrub.
