I'm just starting off with a set of tubulars.
I had to replace one of them recently and found an exceptional amount of rimcement residue and even some old leftover rubber in the rim from the old tubular.
I went at the leftover rimcement with some Xylene- which is a solvent similar to Paint thinner with minimal sucess.
Does anyone have any advice as to what the best solvent is for removing old rimcement?

Sticky Fingers.

Acetone does it. I think you can get thsi at yr local chemists. You don't need to remove every last bit of the old cement - just any big blobs that will make the new tub lumpy if left on there.

xylene should in theory work better than acetone... if you can soak it in the xylene that should help...after that i think that a little elbow grease should do the trick

I got acetone from a LHS and used that along with one of those plastic tire levers to rub off the residue. worked good.

Depends on the adhesive... Xylene should also be used with plenty of ventilation. That's the stuff in glue that people huff. It can also ruin clothes and shoes depending on material.

ya it does depend on the adhesive but most commercial adhesive removers have xylene of some sort of xylene deriative in them.....and xylene is a carcinogen as well

acetone is pretty nasty stuff too. home depot has it. it'll be in the paint section.

So nasty you put it on your fingernails. I don't think it is a recognized carcinogen like the aforementioned xylene.

acetone actually is classified as a carcinogen if you look at the msds for it

hey nothing is bad as the glue he's gonna have to put on those rims later.
tried that soyo glue with Ceya and ELC...dude we were so high

what do u mean we ? not me....lol

S/F,
CEYA!

Way too much chemistry smarts here for a bike forum. MSDS? Come on people...

I have really good luck with Goo Gone or Goof Off....They are citrus based....don't stink and get ya all light headed. If you use acetone I would recommend rubber gloves.

acetone in nail-varnish remover is diluted with water and stuff. in its pure form it's pretty nasty stuff.

if acetone doesn't work you could try sanding it off.

I'll have to try acetone- I'm still pretty lit from that soyo rimcement and xylene cocktail from earlier.- thanks for the tips - Grim

MSDS this!

explosive mixtures with air.

Toxicology

Harmful by inhalation, ingestion or skin absorption. Irritant. Liquid may
cause permanent eye damage (corneal clouding). Contact with skin may cause
defatting, leading to irritation. Long-term exposure may cause liver damage.

i don't use anything. I just leave it the way it is.

ha! be sure to sniff it every 3 minutes 'til you're sure it's setting right!

from personal experience: Forget Acetone and Lacquer thinner or the Citrus stuff, unless you want to spend a lot of time scrubbing. The bomb is any paint or mastic remover in gel form from your local hardware store or the big evil HD or Lwes stores. Just brush on, wait 5-10 min and scrap will metal butter knife, reapply as required. takes it down to the metal in at most 2 applications, do a whole wheel in 45 mins. The fumes are almost non-existant. a $5 can will do more wheels than you possibly need.

pooper,
do you happen to remember any brand names for the gel? My local HD has terrible stocking practices...
Thanks
