Where to find Rydlyme?
« on: April 01, 2019, 08:04:24 PM »

Hi all, I'm OK paying $31 for a gallon of Rydlyme. But $17 for shipping? Not so much!

Is there a brick and mortar place that sells this near me (Philadelphia area)?

Also, am I correct that Rydlyme can be used for cleaning both the raw water side of a HX (clean in place without having to remove, as Ron Hill does with Lime-a-Way), as well as cleaning/flushing the EG freshwater side (presumably for descaling cylinder liners and the outsides of the HX tubes without disassembling)?

If I can't find an acceptable source for Rydlyme, I see that Lime-a-Way is available at my local Home Depot for $5 for just under a quart. However, I've read the arguments against Lime-a-Way because it is claimed to be strong enough to cause damage to the metals. Has anybody looked over the SDSs from these and come up with a dilution formula? If not, I'll consider doing some calculations myself:

Rydlyme 5-9% HCl, pH "Unreadable, generally < 3":

Lime-a-Way "Toggle" version 5-10% sulfamic/sulphamidic acid CAS 5329-14-6, pH 2 to 2.2:
http://www.rbnainfo.com/MSDS/US/Lime-A-Way%20Cleaner%20-%20Toggle%20EN%20GHS%20US.pdf
Interesting Wikipedia article that mentions Lime-A-Way: https://en.wikipedia.org/wiki/Sulfamic_acid

If nobody had done this, I'll do some molarity and pKa calculations to see what dilution of Lime-a-Way might create a similar activity as Rydlyme.

I'd gladly bypass all this and just buy Rydlyme if I could find a suitable local source. If not, it sure looks like Lime-a-Way could be diluted down to an idiot-proof (or even sailor-proof) level of activity, and the convenience of running down to Home Depot may be tempting.

Give em a call (website) and they’ll give you the local distributor. I know mine but not yours!

Or, get muriatic at a big box and CAREFULLY dilute down to rydlyme.

I have the same challenge. I called them APEX Engineering yesterday and decided to get it from Amazon. That is until I saw the enormous shipping cost. I'm calling them again. The good news is APEX was very responsive and the tech support is very good.

APEX USED to have the distributors listed on the website, which is how I found my local one.

Maybe mention that they should restore that!?!

I've use Lime-Away to clean barnacles off my prop and rudder straight out of the bottle.  Seems to work great.  Did not damage the metal on my bronze prop.  Got it at HD.

I called today and the nearest Rydlyme dealer is on the Jersey shore, 2 hours away. The guy told me that Philadelphia is "too land-locked" for them to have a dealer nearby. He told me to "buy it on Amazon." I'd gladly buy it on Amazon with free Prime shipping, but Amazon does not actually sell Rydlyme. Their company is the one selling it using Amazon Marketplace as their portal, the they are the ones who choose to charge over $17 for shipping. When I pointed this out to him, he acknowledged that Amazon does not actually sell their product.

The last I bought for a project was 5 gal; $103 $/ 18 UPS (fairly local.)  There's probably a chemical special handling surcharge on it.
Would Carrier Enterprise UPS it to you?

I'd mail you some of what I have but I'm 700 mi away!

The local industrial pump service shop uses it for descaling -- maybe call around and find a shop local that will part w/ a gal?

Try ProcessFlo in Wilmington - on the way to the boat.  Maybe the pump service manager will sell you a gal.
