Cleaning the room where your programmes are stored: what to

[MeryClean]

I work in professional cleaning, and one thing I see often is that the room where paper collections are kept gets cleaned the wrong way. Dust is the first enemy of programmes stored in a loft, garage or spare room, but wet mopping or spray products close to the boxes add moisture that paper absorbs quickly. It is better to move the boxes out first, vacuum the floor and shelves with a brush attachment, then wipe surfaces with a barely damp cloth and let them dry fully before the boxes go back. Strong-smelling products and bleach-based cleaners are best avoided in the same room, as the fumes can linger for days. Any musty smell or dark spots on walls or skirting boards usually point to damp, which should be treated at the source before it reaches the collection. Keeping boxes off the floor and leaving a little space around them also helps the air circulate. For those of you with big collections, how do you store yours, and have you ever had problems with damp?
