Hot Patch 

Hot patches are put on with heat and 
pressure. They are stronger and more durable 
and resist heat better than those set on with 
rubber cement. 

Materials for making a hot patch come in a 
kit with complete instructions for using. The 
"patch," as it comes, is a piece of rubber 
protected by Holland cloth, as is the cold patch. 
This patch is mounted on the bottom of a small 
pan containing a tablet. When lighted, the 
tablet provides heat to vulcanize the patch onto 
the rubber article. 

To put on the hot patch, first clean and 
roughen the place to be repaired. Take off 
the Holland cloth. Press patch against the 
place to be mended with the clamp in the kit. 
Light the fuse on the tablet. Cool for a few 
minutes; then remove clamp and pan. The 
mended article is ready to use immediately. 

Mending Tape 

Friction tape is a cloth tape saturated with a 
rubber-asphalt mixture that makes it stick to 
most surfaces. 

Electrician's tape is a soft strip of semivul- 
canized rubber that will stick to and insulate 
the wires of electric cords. It comes with a 
coating of Holland cloth, which must be taken 
off before the tape is used.

War in the Pacific has cut off the sources of almost every 
bit of our crude rubber. Practically all the rubber we now 
have . . . and the synthetic rubber that we can produce 

. must go into weapons for our fighting forces. 

Dark. If the place where you store the 
rubber is not dark, wrap the articles in heavy- 
paper or put them in a covered box. Do not 
fold or crease the rubber if you can help it. 
If you must fold, dust talcum powder or corn- 
starch between surfaces that touch each other. 

If the article you are storing is part cloth, 
the storage place needs to be dry as well as 
cool and dark. Otherwise, the cloth may 


Take off oil, grease, and tar spots quickly. 
Usually a bath of warm water and soap will 
do the work. 

If the spot stays on after this treatment, 
sponge it with a dry-cleaning fluid. If neces- 
sary, soak the spot in the fluid — but no longer 
than 2 or 3 minutes. Treat rubber extra 
gently while it has fluid on it. 

Because it does - not catch fire, carbon 
tetrachloride is one of the best fluids for clean- 
ing stubborn spots on rubber. Gasoline is all 
right to use if it has no tetraethyl lead in it. 

"stick-ons." You can buy these along with 
directions for putting on. 

Clothing Made 
of Rubber Thread 

Wash clothing, such as foundation garments 
and suspenders, with mild soap and warm 
water. Handle gently and stretch as little as 
possible when wet. Rinse several times. Dry 
in a cool, airy place away from stoves, radiators, 
or sunlight. If any garments must be ironed, 
keep the iron only moderately warm, and use it 
as little as possible. 

To dry a girdle quickly, roll it in a dry cloth, 
fold over lengthwise so the garters will not cut 
the garment. Unroll and hang to dry. 

Repair breaks with a patch or darn as soon 
as possible. Be careful not to cut the rubber 
thread with the needle. Do not use fine 
thread, because that is likely to cut the rubber. 
Allow three-fourths of an inch margin of mend 
around the spot you are mending.

Garden Hose 

Straighten kinks out promptly. Store on a 
reel or coiled on a flat, dry surface. 

Greatest wear comes near the faucet. To 
repair, cut off the worn section of the hose. 
Put a new coupling on the cut end. 

If the hose wears out anywhere else, cut out 
the damaged part. Put couplings on both cut 
ends and join them. Or join cut ends by 
putting a short pipe inside the hose — clamp the 
hose firmly to this pipe from the outside. 

Hot-Water Bottles .

Dry thoroughly, away from heat. To store,

box. Coil rubber tubing loosely in the box. 
Be sure there are no sharp bends in it or 
sharp objects to cut it. 

Most repairs can be made with a cold patch. 

warm water, and a soft brush. Dry with a 
cloth, or hang in a cool, airy place. Dust 
large articles lightly with talcum powder or 
cornstarch before you put them away folded. 
Use the cold-patch method of repair. If 
you have a piece of self material, make the 
patch from that. Then follow directions for 
putting on a cold patch. If you can match up 
material for a raincoat, put the patch on the 
outside. It turns water better than an in- 
side patch. 

Wringer Rolls 

See that pressure on the rolls is even before 
you put clothing through the wringer. Don't 
stall or strain rolls with too much clothing at 
once. Fold buttons and buckles to the inside 
when wringing. 

Release pressure to separate the rolls after 
each washing. Wipe rolls clean and dry be- 
fore you put the wringer away. Take off any 
stains with a cloth dipped in a dry-cleaning

If there's a small break or worn spot in a rubber article — and the rubber is 
in good shape otherwise — see if you can mend it. Look for mending supplies 
at drug, hardware, and department stores ... at the five-and-ten ... in mail- 
order catalogues ... at your garage or service station. 

Cold Patch 

You can "paste" a fairly strong patch on 
rubber with rubber cement. 

Inner-tube patching is suitable material for 
mending most articles. For raincoats, self 
material is suitable if you can get a patch piece 
large enough — from a belt, pocket, or other 
unnecessary style detail. For light rubber 
goods, such as gloves, make patches of thin 
sheet rubber. 

Here ore step-by-step directions for putting on 
the cold patch — 

1. Turn the article inside out and put the 
patch on the wrong side. Hot-water bottles 
with narrow necks and other articles that 
cannot be turned inside out may be patched on 
the outside. Also, if you have matching ma- 
terial, patch a raincoat on the outside. The 
patch will turn water better that way. 

2. Clean the place to be patched with a dry- 
cleaning fluid. Wipe dry. Roughen up the 
surface with sandpaper. 

3. Cut the patch one-half inch larger all 
around than the spot you are mending. If you 
use inner-tube patching, take off the Holland 
cloth that protects it. 

4. Spread on the rubber cement. Put two 
coats on the rubber you are mending — none on 
inner-tube patching — two coats on any other 
patch material. Let each coat of cement dry 
a few minutes. 

5. Press the patch firmly over the spot. Do 
not move it once you have placed it. Hold 
with a weight or clamp until the patch sets.
