I spray about 85% Sta Flo to 15% water. It did get on my laminate floor which I had to scrub off. It did not sweep or vacuum away. Now, when I spray starch large pieces of fabric, I place a bed sheet under my ironing board. Problem solved! By the way, I've never had a problem with Mary Ellen's Best Press or spray starch in cans; but I don't use them as much as Sta-Flo.

I have wondered this myself! I did notice that when I use a ton of starch my carpet does get a little rough or harder. I do have a steam cleaner though and I usually steam around that whole area about once a month. But that's probably because I May drink and spill coffee and crumbs and things around that whole area too. LOL. Hey! A girls gotta have coffee and snacks when ironing and quilting right?!?! That's part of the fun for me. Great snacks! HA!

I also Best Press over a hard wood floor. I go over the area with a damp paper towel. It's surprising how much of the spray does go beyond the ironing board, but it comes up very easily.

Thank you everyone for you own personal experiences.

Thank you for the question. I spray starch all the time, and my ironing board is on carpet, and have never noticed any change to the carpet. I just vacuum as usual. Now I'll look a little closer!

I have wood floors, use sta-flo, it does get on floor but does mop up. I think if I had carpet, I would use the tablecloth idea, better safe than sorry!

I use a plastic dishpan to spray into. It contains any over spray and when it dries in the dishpan it just flakes off and I put the flakes in the waste basket. I don't like my ironing board and other areas to get wet with the spray.

That's spray adhesive, not spray starch.
