Hello. I recently ran into the issue of cleaning my mattress at home because I didn't want to pay for dry cleaning. In general, cleaning mattresses is very important, since a lot of dirt and dust remains on them even if you don’t particularly stain it - it’s just that the skin accumulates on it, which dies off and turns into dirt and dust, and parasites and bacteria can start in this dirt. In order to protect myself, I decided to take the issue seriously and used the mattress sanitizing machine according to the instructions from the site https://www.fortador-usa.com/blog/how-to-steam-clean-a-mattress-to-remove-urine-sweat-stains-dust-mites Here the experts shared their cleaning secrets and observations on this subject. I recommend to take a look.
