Lidl w5 oxi-action safety in a bath

[onesoma]

I've done failed at the googling.

Before I soak some bottles in the bath, is this stuff safe to use on enamel?

[onesoma]

Any advice on concentration appreciated also.

Check out what Walter White asked Jessi Pinkman to do when disposing of some bodies by using Hydrofluoric acid and don't do what Jessi did.

From episode 2 season 1

Jesse does not the find the specific plastic bin Walt instructed him to use, so he decides to dissolve the corpse in his bathtub. But the ceramic and metal bathtub also gets dissolved and soon the ceiling collapses followed by a flood of clumpy red fluid, presumably a mixture of the hydrofluoric acid and Emilio's half broken-down remains.

Walt tells Jesse that hydrofluoric acid will dissolve anything except plastic.

Never heard of OXy dissolving the enamel of a bath  ....... It would say it on the back. Make up a solution and put a few drops in the edged......... It will probably just clean it. 

[onesoma]

Yeah, it should say it. It says 'Do not use on varnished or treated surfaces, such as wood, metal, etc'

A bit more googling seems to imply that the active ingredient, sodium percarbonate, yields hydrogen peroxide: http://en.wikipedia.org/wiki/Sodium_percarbonate

Some other pages imply that it's grand to use hydrogen peroxide on enamel:

As you say Damien, it'll probably just clean it!

I use it in the bath all the time, especially for de-labelling bottles. Had no issues so far anyway. I use maybe 4 or 5 big tablespoons of Oxi for a bath full of bottles. I also clean most of my gear (kettle, MLT, etc) in the bath with Oxi. Ceramic bath, haven't noticed any issues. Just do what you'd do with anything else you use Oxi on and give it a good rinse with hot water.

so the important lesson we learnt is that oxi is not Hydrofluoric acid so we cant easily get rid of bodies.

back to buring them in the garden then

[Qs]

True but we have some damn clean corpses now.

Lidl's W5 Oxyclean contains Sodium perCarbonate.

This a strong alkali.

Glass is an alkaline silicate material and strong alkalis disolve glass!

Any one who has stored strong caustic solutions in lab glass bottles with ground glass stoppers will know what I mean

Anyone who has steeped bottles in strong W5 will notice that say after 2 days they are spottless. However rinse them and let them dry and you may see a powdery film on the glass (its not a powdery film but mild etching). Handling and the like quickly polishes up the bottles.

So I would not recommend the bath! Much better is to use a fermenting bin/boiler as this will come up squeaky clean as well

just found out today not the first time bones have been found under someones shed

@Will
would it not be sound for short term use in the bath given most cleaners are Alki based.

I've had the white oxy grit occasionally on glass and also on stainless steel and plastic.
It comes off with a good scrub or a soak in acid like starsan or citric acid.

Yes they are and are fairly weak and often state "rinse after 10 mins" or so.

W5 can be made up much stronger and left for as long as you like 

So if its fairly dilute and left in for not too long then I am sure its OK but the point of W5 is usually to soak the subject material for a longish time.

Also its best to wear rubber gloves to protect your hands as some have posted pictures of raw red hands from W5

Bow your heads children as we say grace, thank you Lord for providing us Homebrewers with W5
