Where to hang pictures
Try to avoid hanging pictures above radiators or fires. Rapid or extreme changes in temperature can cause paper and wood to dry out and adhesives to fail prematurely.
It is always best to avoid hanging framed pictures in humid conditions. Damp can cause pictures to ripple and encourage fungal growth. Certain conservation techniques can mitigate against damp so if in doubt speak to your framer and he will be able to advise on the most suitable framing methods,
Where possible, it is better to avoid hanging in strong direct light (opposite a large window for example). UV light will fade works on paper. Anti UV glass is available but expensive (although probably worth the extra for works of value).
Cleaning
Don’t use cleaning fluids or water on frames – a gentle dust is all that is needed. When using glass cleaner apply it to the cloth rather than spaying it directly onto the glass. This will prevent it from running down the glass and potentially damaging the frame or your artwork.
Regular checks
It is a good idea to check your frames periodically to make sure the fixings are secure and that the brown paper tape sealing the frame is in good order. If you find that sealing tape has come unstuck, return the frame to the framer. Do not attempt to replace the tape with masking tape; it is not up to the job! Oil paintings on stretched canvas may become loose over time but can be restreched by your framer if necessary.
