i have 2 goretex jackets in the van(north face and berghaus) and use one in the morning and one in the afternoon on wet days.today ive got decathlon hiking trousers on(cost me round £40).they are waterproof and warm.caterpillar composite toe waterproof boots and im good to go.i also wear a cap sometimes and put my hood up over it to reduce rain getting in my eyes.
gloves wise i usually wear nitrile glove liners with showa 377s over the top.they are waterproof and because i wear the liners my hands dont stink.....
seriously just go out and work in the all but the worst rain....it very rarely hammers it down all day.sit in the van during the very heavy showers.....
dont kid yourself....if you miss a few days of work due to the weather that money is for lost forever.you never "catch up".it has a knock on effect on your whole workload for the next week and week after that....
if you work (say 5 or 6 hours a day) you might have to work in 2 hours of rain if your unlucky....also most customers will either be out or not even mention the weather.the very rare ones that dont want theirs cleaning in the rain get missed until next time.
you might feel a bit miserable working in the rain but you ll feel worse sat at home not earning(from my own experience)....
ive got plenty of money in the bank and im not struggling financially but id rather be working than sat at home.it would be different if my missus was off and we could do something together but shes self employed as well and works hard most days so i might as well be working too....
