2 weeks ago I emptied my outdoors spa and cleaned it, filled it back, heated it and used it was nice and enjoyable.

Went to use it this Sunday after a sail, sat in it and it was like seating on sand paper, lot of sand? has attached itself to all the submerged surfaces and is hard to brush out.

The spa is covered and I have not put chemical in it as the PH was about 7.2 and it has an Ozone generation sys. I just put a bromine tablet in the floating device.

Has anybody had the same problem?

Prob #2: It looks like a white deposit is forming all around the edges just above the water top, tried to remove it with all sort of cleaning stuff from soap to CLR..... nothing looks like to remotely touch it!

Any ideas?

I'm currently looking at getting a spa and the guy at the spa shop it is usually associated with calcium deposits or chicks that wear make-up that get in.

^yeah prob calcium from tap water, sometimes not possible but rainwater is a good neutral base to start from and easier to balance

Encrusted Jizz deposits?

stop peeing in the spa !

Your spa is host to an alien life form.

Thought that pee been acidic it would remove the calcium deposit??????

The spa guy told me to polish it with some stainless steel cream.............. tested on a small bit looks like it working but hard work
Have hit the surfaces with high pressure cleaner and the sand is getting loose. Still neither myself or the spa guy understand why it glued itself to the spa walls?????

Go to the beach

Do that all the time.......... water in the spa is warmer and very kind to my frozen shoulder!

Get a clay bar from the auto shop or panel beaters. Believe it or not it works, they are usually used to get overspray off and is quick and easy just spray the surface with some detergent and water to lubricate and it should take most off first pass. It might even take the sand off too.

^^^ will try it.... never heard of it.... what is it, some sort of sand paper?

It's literally a piece of clay, it works by sliding over the paint on the lubricant (have even used just water) and anything stuck to the surface grabs the clay and is pulled off (eg;paint overspray, metal filings, oxidised paint)

I bought a kit and it is working.... lot of scrubbing required but it is removing it!
