I wash mine in warm water with a mild detergent. I line dry them or use the dryer with no heat. Hot water or high heat will damage the fibers. For my microfiber mop heads that I use for the shower floors, I occasionally soak them overnight in laundry soap and the put them through a full wash. Once they start losing their effectiveness even with washing, I toss them and buy new.

"Once they start losing their effectiveness even with washing, I toss them and buy new."

Yep, agree -- but the thing is these are relatively new, I think only a year old, they shouldn't be losing their effectiveness already. Unless they're just not the same quality is the ones I had for many years that I finally had to replace.

I washed a very small load (8 pieces) of microfiber cloths yesterday. Water temp slightly warm 100°F-ish. STPP for water softening and a small dose of Ariel powder. Machine dried at lowest temp which is 127°F at most. My electric dryer has two heating elements, 1/3 (1,400 watts) and 2/3 (3,600 watts) of heating capacity. Both elements operate for high temp. Only the 2/3 element operates for low (and medium) so the input airflow is at a reduced temperature for heat-sensitive items.

I wash my cloths with normal towels and jeans, cold water, but I don't put them in the dryer, just lay them over a coat hanger to air dry.

We air dry ours on our laundry rack. We don’t use any kind of fabric softener or dryer sheets. Because this is a microfiber cloth thread, does anyone have a suggestion about microfiber cloths that are as good as the ones that they used to sell it at Solutions? Solutions is no longer in business, and I honestly get anxious when I think about the fact that I can’t order more of their microfiber cloths.

I never wash anything in tap-cold water. 90°F to 95°F is lowest for so-called sensitive items. My normal warm is 112°F to 116°F. 130°F to 140°F for hot whites ... socks, kitchen towels & dishrags, bath towels & washcloths. Keeps the washer clean, I've seen too many smutzed-up, stinking machines caused by cold water.

Do you wash the microfiber cloths with anything cotton?

"Do you wash the microfiber cloths with anything cotton?"

Never. They will pick up every last bit of lint. Always wash them in a separate load.

"Do you use ever fabric softener dryer sheets? If yes, perhaos the residue in the dryer drum has transferred to the microfiber cloths? "

I do use dryer sheets, but not in the microfiber load. I never thought there could be residue, maybe that's what the problem is.

"...but I don't put them in the dryer, just lay them over a coat hanger to air dry"

I guess I could start doing this, I have a drying rack in the basement, but I have about 10 mop heads I do at once and I'm kinda lazy to trudge it all down there. If I buy new ones I might have to resort to that, though.

I wash mine by themselves in the sanitize cycle at 170F with Tide powder and then tumble dry on low.

I wash with regular towels in the washer, and cold water. I put the towels in the dryer on high heat, but, all microfiber cloths, I hang on a drying rack. I did just replace two of the floor pads for my mop, but, old ones actually had holes in them, because, of age.
