All my clothes and other fabric material were contaminated by formaldehyde used in pressboard. Some clothes can be washed others dry cleaned. Fabric/cloth chairs were also contaminated. This happened as a result of a hole being drilled in the side of a wood frame travel trailer and not sealed as requested. When the hot sun penetrated the walls it released the formaldehyde in the pressboard and the formaldehyde contaminated everything. It is still strong after four years and I have tried everything recommended on the Internet to no avail. Anything placed close to the items that are contaminated also become contaminated.
