I cleaned the windows and he came out and said

 "how long does the water stay on the brick work after your gone, if it freezes it will damage the bricks".

Do you think I should dump?

Ask what happenss if it rains and then it's cold later on.

Only had one customer ask this and explained that the DI water doesn't contain some harmful elements that tap water contains.

Never heard or noticed at before. It must not damage the brickwork.

Tell him it doesn't stay on the brick work any longer than rain water would. Bricks are designed to get wet!
