I'm trying to modify an existing dress and I have some questions.
1. Can I steam a velveteen dress in the dryer (put it in with a damp towel)?
2. Can you - and if so, how do you - get hot glue off of velveteen? I hot glued pearls to the neckline of the dress before I knew anything about sewing :-X.
#1: Yes. Absolutely, I do it all the time to my peacock blue velveteen Irish gown (I made it without pre-washing the fabric--which I would do now--so it's my best option for keeping it clean).
#2: No idea! But I'd start with picking off all the excess that you can, and then using heat (like an iron) to warm up and peel off the rest. You probably won't be able to get it all off or get everything off without damaging the pile, so you'll probably want to replace the glued-on trim with something else.
If you have the means to invest in a good Professional Styled Steamer, that will help as well as the garment hangs. I have ironed Velveteen carefully at the highest settings, with light pressure on the fabric itself. But prewashing the fabric can be helpful at first before garb is made if puting in the washing machine is going to be the procedure for cleaning.
I hand clean our garb with a clean towel, wetted down with AMWAY's L.O.C(Liquid Organic Cleaner). This amazing product breaks down dirt like no other. I order the hand towelettes to carry in the event of splliage. No damage to the fabric at all. Dirt is gone. I do this because of the trims used, beading, etc.
But each person has their own procedure for Garb Maintenance.
