I'm cleaning a lot of mattresses with dynamall next week.  one  sprayer with regular dilution and a stronger dilution in another for heavy marks.

I know it contains hydrogen peroxide but was wondering if using hydrogen peroxide as a stand alone spotter (maybe on blood marks) or as a paste would be any use?

Works well on mattress don't it....I don't do many but those I have done have used Dynamall and they came up great.

Did a batch today although a couple had blood spots on.  Any tips on this anyone?

Rust remover. Thorough rinse though. Bring in a spotter with you and dynamal the rest of it.

if it comes to it it with the blood spots  ...  i have a four emulsion paint testers of various shades of off white to grey
dap a bit on with a q-tip and rub it in ... usually blends fine

I would be ... first try cleaning with something like citrus prespray and high heat from an inline heater through my cfr tool
If that don t work ...  hair bleach time ... make up the paste and brush it all over the mattress with a 3" painbrush ....
The hairbleach is so strong most things will start to dissapear instantly ... u can speed up a spot by applying heat with a hair dryer .  carefull though , a close hairdryer can burn a mattress , and then your be painting a burn ( iv done it )
Lately i dont even fully remove the paste , just vac it off and leave the residue to bleach , i turn it on its side and put two airmovers on chairs against it for fast drying , after the hair bleach is dry and released its peroxide it should be inert anyway .
