looking to clean up a set of 4 motorcycle carbs by soda blasting - not sure how much media I would need but guessing 10 kg would do (2+ kg per carb should be enough?)

so where can I get 10 kg from? it would be great if MMart sold it but I don't think they do - ebay has it but in larger quantities and post is quite ££

(I am near Watford if anyone know of a local supplier)

Not local but Frost Auto Restorations do it it 5kg Tubs and its nice and dry unlike some of the stuff on fleebay.

linky? can only find 25 kg tubs

hmmmm .... found some on ebay 10 kg for £ 16 - need to search for baking soda (not blasting) and it does state:

Uses:

Bath Bombs – we recommend using 2 parts Sodium Bicarbonate to 1 Part Citric Acid. We also sell Bath Bomb kits with the correct proportions of these ingredients in our eBay shop for your ease of use
Antacid - For over 12 years add 1 teaspoon to water and take every 4-6 hours
Great natural cleaner - just use with a little water and for a fresh smell a few drops of lemon essential oil
Suitable for use in marine aquariaums
Abrasive - for conventional shot blasting equipment

They used to do it in 5kg Tester Tubs. Salt also works.

Postage isn't even too bad - a lot cheaper than the ebay price.

Tried using that stuff, must be doing something drastically wrong 'cos it ain't working Just covers everything in dust!

Try your local Chinese supermarket, I buy it in 3kg bags for £3.50.

I use Miller Soda Blasting. Their stuff comes in 20kg bags, and has a water resistant coating on it so it doesn't clog. I drove over to see them and had a good chat as well. They restore cars there so they know what they're talking about.
