I know how you feel, I had a customer who brought in a 6' cybachrome print from the US, several thousand dollars worth and cybachrome has a very high gloss which will mark if you even look at it.
My advice, don't let liquids any where near it especially water, if you use a spray cleaner make sure the photo is covered and or a long way away, atomised droplets can hang in the air and land on the photo some time after being used especially if there is also someone else working in the workshop. Don't even have any liquids on the same bench including tea and coffee. To remove dust don't touch the surface use a vacuum cleaner held off the surface. If you have to touch the print use cotton gloves.
Oh and hold your breath if you are leaning over the picture and don't cough over it.
Check the mounting to see that it has been done properly, conservation mountboard, adhesives and T hinges.
Good luck, it's only a picture.
David.
