removing silicon/glue

[obiee]

hi all
i bought a alloy tray off a bloke who had jet ski's and had marine carpet glued over it he used silicon and some sort of glue. i pulled carpet off no probs but there is still a fair bit of silicon left on tray and have been trying to remove it.
i have tryed everything goo off, petrol, thinners, even soaked in wd 40 which worked ok to soften it up a bit. i have tryed to scrape it but the little ribs in tray make it hard. some bits of silicon is 5cm thick.
anyone got any ideas on how to get this off

Sounds like you've had a fair crack at it already.
Usually at work on machine guards or enclosures we have sealed it with we just scrape it off but yeah with being ribbed that would make it hard

What about a pressure washer?? That should lift it.

Cheers

Heat gun, hair dryer or paint burner.?

Hot water?

I usually give it a wipe over with a rag of diesel let it soak for the night then it rubs off in the morning. Maybe gasket remover would work on it if you have any about

Bunnings sell a product called
K9P works really well it but can be hard to get hold of might have to ask for it.

Frig me that must be good silastic

[crintonn]

If it was silicon i thought it would have blown off.
Are you sure its not contact adhesive?
That would make sense why its not lifting, as that's more of a glue.

wire wheel on a grinder

You have a couple of options but most have been touched on.
Im a toyota dealer and have 4 detailers working for me in the used cars department, we have had things like this in the past.

The problem with alloy is it some cleaners like acid, will turn the alloy a milky colour and this is hard to repair. its a massive polish job from their.

Heat is your friend in this case, Leave the tray out on the sun for a day to heat up the silastic.or use a heat gun.
wd40 is a good product and it will penetrate well,(as long as the silicon is a pertor base) I have also used eucalyptus oil , this works very very well.

IMO i would soak with wd40 and eucalyptus oil a couple of times in the morning before lunch, and work it in very well with a paint brush, Then go to carlover or the like mid arvo and use their pressure washer as it may have a bit more pressure, Hold it close to the tray, and hook in.

Failing that, a cheese wheel on a drill is a good option these are used to remove stickers from car doors, it can burn the paint but alloy should be ok. (pick one up from supercheap about 30 bucks)

Steel wool or fine wet and dry sandpapper (this is a hard option) and it may scratch the alloy, but if it does a light posilh by hand should remove the scratches.

or a flat screw driver the size of the groves so to speek. (aslo just thought cut some notches out of a scraper to fit the ridges)

But i just thought if you were to un bolt the sides and floor, I wonder if you could flip the floor over so the top is the underneath and visa versa. (that was a last thought and i bet ill read it back and think to my self D*%khead that wont work)

But ill put it out their anyways.

thanks fellas
lol yeh tryed most of all the options you have given me it is a silicon (grey looking) and its soft to touch not hard i too was thinking of a scraper with notches cut out.
i am not too worried about the tray going dull as its not polished anyway so might just keep hitting it with wd etc and putting pressure cleaner on it.

Did you try my suggestion

I also think they do sell a product that breaks down silicone
Pretty sure it's a sika product.

i will call into bunnings tomorrow and see what they have got. cheers

Most marine shops sell a product called debond, it works on silicon and sika products pretty well.

[Rooboy75]

First answer on google, selleys silicon remover. Bunnings maybe an easier option mate.

[Oxstrom]

There is a product by Red Back called Silicone clean up but not sure what effect it will have on the Aluminium tray.

Go to Bunnings and get a hand full of those rubber door stoppers, the ones with the screw hole. A 3" long screw through the hole with a washer either side and a nut, put assembly in electric drill and it will tear the silicon out,


Your welcome Ashy .
