Hi Everyone. I'm not sure if I should post this here, or in the Gucci Care thread. I figured this would be a good place to start.
I just got my first vintage Gucci (a speedy/doctor bag from the mid-1980s) in navy with the ( very flakey) navy lining. Little did I know about this common problem of the flaking/dusty lining until I got the bag and was like "what the ?". There was no way I could use the bag without everything I put in it turning blue. I searched on tPF and found a few threads, but nothing too helpful.
I think I found something that works. I got out my super-suction Dyson vacuum, put the brush attachment on the end of the hose and vacuumed away all of the left-over blue. It took some time, but it sucked all of the old, dried, blue off and it worked beautifully! I am so excited and don't mind at all how the lining looks now. It actually looks like a light blue micro-fiber. Then I stuffed it with dryer sheets to take away that vintage smell. The bag looks great all around and no more blue dust.
This may not be everybody's solution if you want your bag perfect (then definitely send to Gucci for a new lining). I just didn't want to spend the $$ on a new lining but didn't want to deal with the blue.
I hope this helps.
