Best way to clean plate Hex

[bassmonster]

Hi all, as per title. What's the best way to clean plate hex. My mate uses sulphuric acid with hot water. He puts the hex in a bucket, pours the acid into the heating side, let's it soak for a few minutes then pours boiling water in the bucket until hex fully emersed in water, leaves it for about another 5 minutes then repeats once more....

I don't bother. Just replace, I tried it once and it didn't work the same as a new part.

Fernox DS40 granules in the heat-ex then fill with boiling water. Immerse in boiling water and boil up for a while. Rinse through and repeat depending on need.

Makes them like new.

lol bet the customer was impressed

customer was more interested in what came out and after said "that's a clever way of doing it".

personally would not put sulphuric acid any where near water unless you want a couple of days in hospital as it will go up in your face!!

bin it buy a new one and bill customer, how hard is that?

 

[Rabbitman]

I just swop em, it's easier lol......

 

[REDSAW]

rather have £20 extra for supplying new one than £20 worth of burn ointment.lol

Give customer 2 options:

New hex £100 + £85 fitting (or whatever you charge)

Refurbish hex £50 + £85 fitting

Aka I make £50 more and they save £50 and the heat ex is as good as new.

good luck with trading standars with that one!!
your not supplying what you state/exchange. your cleaning it only so if it splits later they can have you.
it also takes longer so your £85 labour is incorrect

sulphuric? goes bang with water,sure its not phopheric acid ? if its the later pointless adding water to the mix as it neutralises it

Definitely sulphuric acid....

dont do it mate,basic science Do You Add Sulfuric Acid to Water or Vice Versa?

 

[Ermintrude]

Acids usually diluted so it's got water in the solution any way?
