How to disinfect foam rubber?
For example, is it safe to use a bleach solution in water, or will that deteriorate the foam rubber quality?
An advantage of a homemade foam doll is that I can replace it low cost, if it is worn down, or damaged.

Thanks, I think you're right. I can experiment with slivers of the same foam rubber in different concentrations of bleach solution, for a fixed period. What period and bleach concentration in water is needed for adequate disinfection?dbenzguy wrote:There are so many different formulas to achieve foam rubber, it would be extremely important to know the composition of the foam before determining what may or may not harm it.
Of course I will rinse off the bleach thoroughly a number of times, after the disinfection treatment of a foam doll.

Test, test and test again

After disinfection the bleach should be rinsed off completely, since chlorine is a very toxic and irritant chemical.dbenzguy wrote:I can only assume based on general cleaning recommendations that say to wipe it on and let it air dry.

Foam rubber from a coach-cushion or bed-matress most times has an open cell-structure. Hence it has to be fully soaked in a disinfecting solution for a certain amount of time, to be disinfected.dbenzguy wrote:I've never used bleach on my dolls so I can only assume based on general cleaning recommendations that say to wipe it on and let it air dry.
I have soaked a sliver of regular yellow-gray couch-cushion foam in bleach, for a 22-hour period, at room temperature, as an experiment.
Directly after that period the bleach was still liquid. Then I rinsed the foam rubber sliver twenty times with clean water, while pressing the water through it. After quick drying in a dry cloth, that sliver was not visibly changed in any way, in shape, structure, color or texture.
The bleach used consisted of 4% sodium hypochlorite in water solution, as in regular bleach products, without further dilution by me.
That concentration and 22 hour time-period are much stronger and longer, than necessary for disinfection.
Yet I have read several warnings on the internet, that foam-rubber would not be resistant to disinfection with bleach. Maybe that advise applies to other types of foam- rubber than I have tested in this experiment, or that advise is unjustified.

Glad to see that your testing is going well!John929295 wrote:...

I didn't find any recommendations on foam rubber, just general cleaning instructions. It sounds like your method should kill practically anything that gets into the foam

Disinfection is only effective after all visible contamination is washed off thoroughly from a material, like after a flooding.dbenzguy wrote:It sounds like your method should kill practically anything that gets into the foam
