I like the old way, but the new way is quicker and produces better cleans, that stay cleaner for longer.
However i may introduce back ladder window cleaning and charge extra than what i charge with wfp, where there is no real safety issues.
Ive not stopped using ladders, its just most properties are ideal for wfp. However i do have some where wfp is impracticable and ladder use is quicker and easier.
