Hi Ricardo.

I use one to two dessert spoons of citric acid in 1 litre of water. I
clear for at least 2 minutes (even if paper becomes pure white even
before that). I wash for around 8 - 10 minutes after clearing (changing
water every 30 - 60 seconds). I use COT320 most frequently (hot press,
320gsm).

Regards,
Loris.

Loris,

Concerning the clearing of your cyanotypes, how much citric acid do you
use in a liter of water and for how long do you live the paper in that
bath? How much washing afterwards? What the kind and weight of paper you
most frequently use? Thank you,

Ric
