Hot Tub Covers and 303 ?
« on: July 28, 2010, 12:48:24 pm »
Not trying to rain on anyone's favorite product or anything, but I'm just trying to get my head around what happened.
I'm a long time tub owner and I'm on my second hot tub as my info identifies. In the 14 years I owned the Vita, I had the original cover and one other.  The second cover at 7 years could have gone probably a couple of more years had I not retired the tub.  My regimen for cover maintenance was simple: hose down as needed, any kind of protectant (Armorall, STP, etc) monthly, and clean 1-2 x/year with Leisure Time cover cleaner (can't remember the exact name of the product.)
When I bought the Sundance new in 2008, I maintained the same regimen except changed to 303 exclusively.  Didn't seem to have any issues until recently when the top of my cover appeared to lose color.  Tried cleaning with the Leisure time product and no change.  Cleaned and applied the 303.  Since I am off on vacation, I decided to see what the issue was.  So I broke out the Lestoil and a scrub brush and had at it.  All the discolorment came off and the original color for the most part is back except for a milky film that will not come off, even with power washing.  Also, the vinyl appears to be brittle in places to the point that I know that this cover isn't going to go the usual 7 years.  I'm frustrated that I wasted the time and money on product for this kind of result.  Therefore, cleaned it up as best I could and put Mr. Clean protectant on it (free w/mail in rebate @ Ace Hardware.)  Doubt that I am going to buy 303 anything any time soon but my question is what caused the milky film?

One thing to keep in mind is that, vinyl in not vinyl. A lot of the vinyl more recently has been coming out of China and South East Asia. It is NOT necessarily the same quality as the domestic vinyl that has been used in the past (though some is...and some of the previous domestic product had problems as well).

There's a chemical process to make the vinyl, and different companies can use different formulas and/or slightly different raw products, to come up with a product that will visually appear the same, but preform differently over the long run.
If you can't sell it on eBay, it may not even qualify as landfill.

Retired (mostly) from the industry after 33 years...but still putzing around with a consumer information website, and trying to sell obsolete owners manuals

Doc's right.  Your issue was the vinyl not the 303.  We've used and recommended 303 for over 20 years.  The 303 didn't change, the vinyl did.

In 2008, Sundance used Ideal Spa Covers primarily for their covers.  Ideal was using a fabric sold by RKB Morbern that was sourced in mainland China (for years LG made SpaHyde for Morbern and it was fine).  They had a problem with quite a bit of that vinyl.  The tan was turning black while the browns and rust colors were fading badly.  Sundance has switched half of its production to another LA-based manufacturer which is even worse because they literally buy the cheapest vinyl they can find.  IMHO you need to source fabric that has a track record.  My guess is you just got a bad batch of vinyl with your OEM cover.

These days with the economy the way it is, many of the supersize cover manufacturers are cutting pennies and fabric is an easy place to do it.  We were speaking with a Mexico mfr earlier this year about their spa line that used to be 28 oz.  When I questioned how light the new sample was they said they had switched to 25 oz to respond to demand for lower prices.  Their largest spa cover customer is a place in Florida that will remain nameless. That facility builds the covers for many of the eBay merchants and a handful of decent size online retailers.  Of course, you don't find any of these guys changing their websites to reflect the lesser weight fabric they are now selling.  In some of their defense, they may not know as I doubt the cover manufacturer in question has volunteered the new information.  That said, they're prices are very low and their clients know what kind of cover they are selling.

A little off track, so I apologize.  The point is costs are going up but the public doesn't want to pay more.  As everyone tightens their belts, fabric is the easy thing to trim from for a lot of these big companies.  If it's not the weight, it's the additives.  All red-based colors are very expensive to produce because it takes more dye to sustain a red-based color over time.  Less dye = early fading.  A way some of these mfrs have cut price is to back off on additives.  Some are color-based, many are resistance-enhancers like UV resistance and chlorine and bromine resistance.

Sorry for the long answer, but the reason your 15 year spa had better covers is because they were made of better fabric.  Hopefully, the manufacturer you choose for a replacement cover uses better fabric than your OEM cover.  But rest assured, the 303 is not your issue.

our cover source for after-market covers let on that they have a troubled batch of covers in circulation that they sold around 3 years ago.  the failure is exactly as you describe.  they acknowledge it as a defective batch of vinyl and are replacing them even after their warranty has expired in a show of good faith.  303 is a good product imo.
