Hi all,    does  anyone know the  exact  make up  of Micro Set please?   reason I ask  is  -  I read  its  diluted  White Vinegar?

 

Long story short  I need  to do a minor microwave oven interior  repair  to a  bit  of  seam rusting,  and  I read  you can treat rust  with  White Vinegar,  then paint over the  top of it  with  microwave safe  enamel paints.

No one knows for sure cause microscale refuses to release the formula and the people who do the MSDS on such things refuses to make them...

 

Which means it is not a hazard to anyone's health, or is a toxic chemical... Micro set... the overall internet opinion on it is Acetic Acid.. A completely natural product you can buy it by the gallon without restriction... 

 

So no I do not believe that Micro set is diluted white vinegar, it is acetic acid.... They are two different things although coming from the same source...

 

The sniff test is what most everyone uses and it smells like vinegar... For doing what you want to do? go to your local concrete supply house or big box store and buy a quart of acetic acid, then you will have the proper grade for doing such work as etch cleaning rusty metals...

I think the concentration of acetic acid in Micro Set is too dilute to be of any significant use other than for decals. Most household vinegar is about 5% acetic acid by volume, Micro Set might be somewhere around 2 or 3 percent (I’m no chemist, just my own personal guesstimate).

Thank you kindly brother,     its  such a tiny area  inside  at the  back  along the  seam.

I don't know anything about this application, but if what you want is higher concentrations of acetic acid, try an old time photography supplier.  In the wet lab darkroom days, "Stop Bath" was approx. 2% acetic acid, but the stores stocked 28% acetic acid, and also "Glacial" acetic acid, which was straight anhydrous acetic acid.  You can then dilute it to desired strength for your application.

This  is the  area  I need  to treat  and  hopefully  touch up with a  small tin of  microwave  safe  enamel paint.

 

I assume  its  safe to use  at the moment  not  from a  radiation leak  perspective  as  I dont think it is leaking,   but  the actual  food  should  still  be ok  being  cooked  in covered  containers (like  cling film  pricked covers)  shouldn't it?

 

The rusting is only small in and the rest  of the  inside  is  perfect.

Yep, Glacial is used to etch concrete in prep for painting or staining... you do have to figure out a formula to match the application, stripping/cleaning rust is a high concentration job...

Hmm.... why not just use some fine grit sandpaper and sand it down to bare metal then paint?   From the photos I can't tell if any of the rust has gone through the metal completely.

I don't  think it has  as it  still  feels  solid.

 

The  Urgency  to  fix  it  is  its  our only  cooking device  as  our  electric  cooker  stopped  working  and  we have not been able  to replace it  -  so we  are  fully reliant on the microwave.

Do  you guys  think it is safe to use  till  I can  get the  stuff  to  treat the rust and paint  over  those  areas  if the  food  is covered  inside the micro.

I would think so, OC.  I do a lot of microwaving being single and lazy and I cover everything as part of the lazy is not wanting to clean up the splatter.

Thank you Mark,    was   just looking for  some  reassurance  so I can also   tell the  admiral  as  she has  been  a  bit worried also.

Bit of progress  on this  folks  -  I  got hold  of a  tin of  microwave   safe  enamel  paint from a  microwave  repair shop,  its  supposed to  be the  exact same  type of paint  they  spray  the  inside  of  microwaves.

I turmed it off  found a good  place  to work on it,  then i  made sure  both  areas  to be painted  where  clean and  any loose  fragments  cleaned away,  then  using a small  brush  I started  to  put  some  paint layers  down, drying  them in between with a  hairdryer,   I  put about  Five  layers  down  untill  all  rust  dents  and  marks  where  covered.

I then  turned the  microwave  over  and did the  same to the  other  damaged area.

 

It  was  put in place  and  with the  door left  open  - was  left over night   before  testing it.

 

Hopefully  its  saved our microwave  and  our  health, as I am sure  radiowaves  bouncing off  rust  areas  can not be safe  with  microwaved food.
