I tried the handwash bit for a while myself. I couldn't sustain it. I got a long lecture from Bugelli about handwashing, detergents, etc. It was evident that I shouldn't risk sending these shirts to just any commercial laundry.

Over the years I've used Bowring & Arundel (r.i.p.), Dege, Geneva, David's, Ascot Chang, Bugelli, and Lemmi (Perugia). Bugelli did the best. Worth a journey. He doesn't travel, unless you're in Japan.

I thought Acorn 100 was for single use only.

l send my best stuff to Bancrofts. lt is the recognised place in the Southern hemisphere for certifying the cream of the cream of dry cleaners. Only 5 places in Australia are properly qualified in the green methods (none in Sydney). Expensive but they do a great job. No toxic chemicals, in fact you can put the dry cleaning materials in your mouth to no ill effect.

I only trust Mrs Bishop with my H&K's.

my local guy around the corner at least knows how to do a good roll on a lapel

Here are more laundry tips for travellers -branches of the C. Berry franchise of dry cleaning and steam pressing operatives:-

Well if you ever plan to motor west
Just take my way that's the laundry that's the best

Clean your shirts on Route 66

Well it winds from Chicago to L.A.
More than 2000 miles all the way

Clean your shirts on Route 66

Well it goes from St Louis, down to Missouri
Oklahoma city looks oh so pretty
You'll see Amarillo and Gallup, New Mexico
Scottsdale, Arizona(*) don't forget Winona
Kingsman, Barstaw, San Bernadino

(* Scottsdale branch may involve slight detour)

Buying some shirting cloth from his ex wife was unpleasant enough for me.
