hey everyone, big problem ive quoted for a care home and ive done a tester but everything i used wouldnt shift the dirt, its the grey stains etc, BUT, theyve had someone else in who's supposedly used a water based chemical and ive seen it, it looks brand new, even in the little cracks!!!!!
i really want this job and need to get a chemical which i can just prespray the frames then use my water fed pole to agitate etc.
thanks
