Wayne are you using the new ionics brush you know the stiffer one or not as
it will get all spider and fly poo off in seconds without the tucker price and bytheway im not tight
but the ionics brush is the best imo BUT its the spider mess we can`t get off
Edd:
I haven't tried the new crinkly Ionics commercial brush yet.
I still use the old commercial heads on maintenance cleans for low work and Tucker's for high work.
I prefer the Tuckers because they aren't as soft as the Ionics but are softer than Vikans yet will still remove the spiders mess and fly poo on glass and better still on the PVC sills & surrounds. They're better for removing seagulls poo by tapping the glass and removing their handy work whilst using warm to hot water.
I share your dislike for the old Ionics domestic brush heads as they are too floppy!
Edd is the new Ionics brush head bristles softer or stiffer than the Tucker?
