Sorry lads but getting back to topic here...........i have to agree with matt guys "you wash you rinse" the window is clean
In some rare cases when we have taken over a clean off another window cleaner we have found there to be spotting but we strongly believe that this is down to more attention to detail on the tops of the frames and vents
Hot water guys is no better than Cold water on regular maintainence cleans .........im mean come on lads be it Hot or Cold its pure water at the end of the day, but Hot will out perform Cold when used to clean algee off conny roofs gutters facias cladding etc
we only use hot on really grubby 1st time cleans and in this sort of weather as it allows us to carry on working during the warmer months of the year from april to october we use cold water on regular maintainence cleans as there really is no need to use hot
Hey why burn more diesel if we don't have to
we still have our DIY cold weater system set up in out astra van and from time to time when needed we use this set up if needed, ie when the vivaro has to go in for a service or an MOT or in as in most vivaro cases when it goes i n for a new gearbox
i have a Hot water machine bulit by Ionics systems and also a cold water system built by myself and my father and no machine or temp of water is better than the other they both clean windows to an extreamly high standard
